QFQ Report Keywords

See :ref:`qfq_keywords`.

QFQ content element

The QFQ extension is activated through tt-content records. One or more tt-content records per page are necessary to render forms and reports. Specify column and language per content record as wished.

The title of the QFQ content element will not be rendered. It's only visible in the backend for orientation of the webmaster.

To display a report on any given TYPO3 page, create a content element of type 'QFQ Element' (plugin) on that page.

A simple example

Assume that the database has a table person with columns firstName and lastName. To create a simple list of all persons, we can do the following:

10.sql = SELECT firstName, lastName FROM Person

The '10' indicates a root level of the report (see section :ref:`Structure<Structure>`). The expression '10.sql' defines an SQL query for the specific level. When the query is executed, it will return a result having one single column name containing first and last name separated by a space character.

The HTML output, displayed on the page, resulting from only this definition, could look as follows:

JohnDoeJaneMillerFrankStar

I.e., QFQ will simply output the content of the SQL result row after row for each single level.

Format output: mix style and content

Variant 1: pure SQL

To format the upper example, just create additional columns:

10.sql = SELECT firstName, ", ", lastName, "<br>" FROM Person

HTML output:

Doe, John<br>
Miller, Jane<br>
Star, Frank<br>

Variant 2: SQL plus QFQ helper

QFQ provides several helper functions to wrap rows and columns, or to separate them. E.g. fsep stands for field separate and rend for row end:

10.sql = SELECT firstName, lastName FROM Person
10.fsep = ', '
10.rend = <br>

HTML output:

Doe, John<br>
Miller, Jane<br>
Star, Frank<br>

Check out all QFQ helpers under :ref:`qfq_keywords`.

Due to mixing style and content, this becomes harder to maintain with more complex layout.

Format output: separate style and content

The result of the query can be passed to the Twig template engine in order to fill a template with the data.:

10.sql = SELECT firstName, lastName FROM Person
10.twig = {% for row in result %}
    {{ row.lastName }}, {{ row.firstName }<br />
{% endfor %}

HTML output:

Doe, John<br>
Miller, Jane<br>
Star, Frank<br>

Check out :ref:`using-twig`.

Syntax of report

All root level queries will be fired in the order specified by 'level' (Integer value).

For each row of a query (this means all queries), all subqueries will be fired once.

• E.g. if the outer query selects 5 rows, and a nested query select 3 rows, than the total number of rows are 5 x 3 = 15 rows.

There is a set of variables that will get replaced before ('count' also after) the SQL-Query gets executed:

{{<name>[:<store/s>[:...]]}}

Variables from specific stores.

{{<name>:R}} - use case of the above generic definition. See also :ref:`access-column-values`.

{{<level>.<columnName>}}

Similar to {{<name>:R}} but more specific. There is no sanitize class, escape mode or default value.

See :ref:`qfq_keywords` for a full list.

See :ref:`variables` for a full list of all available variables.

Different types of SQL queries are possible: SELECT, INSERT, UPDATE, DELETE, SHOW, REPLACE

Only SELECT and SHOW queries will fire subqueries.

Processing of the resulting rows and columns:

• In general, all columns of all rows will be printed out sequentially.

• On a per column base, printing of columns can be suppressed by starting the column name with an underscore '_'. E.g. SELECT id AS _id.

  This might be useful to store values, which will be used later on in another query via the {{id:R}} or {{<level>.columnName}} variable. To suppress printing of a column, use a underscore as column name prefix. E.g. SELECT id AS _id

Reserved column names have a special meaning and will be processed in a special way. See :ref:`Processing of columns in the SQL result<Processing of columns in the SQL result>` for details.

There are extensive ways to wrap columns and rows. See :ref:`wrapping-rows-and-columns`

Using Twig

How to write Twig templates is documented by the Twig Project.

QFQ passes the result of a given query to the corresponding Twig template using the Twig variable result. So templates need to use this variable to access the result of a query.

Specifying a Template

By default the string passed to the twig-key is used as template directly, as shown in the simple example above:

10.twig = {% for row in result %}
    {{ row.lastName }}, {{ row.firstName }<br />
{% endfor %}

However, if the string starts with file:, the template is read from the file specified.:

10.twig = file:table_sortable.html.twig

The file is searched relative to <site path> and if the file is not found there, it's searched relative to QFQ's twig_template folder where the included base templates are stored.

The following templates are available:

tables/default.html.twig

A basic table with column headers, sorting and column filters using tablesorter and bootstrap.

tables/single_vertical.html.twig

A template to display the values of a single record in a vertical table.

Links

The link syntax described in :ref:`column-link` is available inside Twig templates using the qfqlink filter:

{{ "u:http://www.example.com" | qfqlink }}

will render a link to http://www.example.com.

Json Decode

A String can be JSON decoded in Twig the following way:

{% set decoded = '["this is one", "this is two"]' | json_decode%}

This can then be used as a normal object in Twig:

{{ decoded[0] }}

will render this is one.

Available Store Variables

QFQ also provides access to the following stores via the template context.

• record
• sip
• typo3
• user
• system
• var

All stores are accessed using their lower case name as attribute of the context variable store. The active Typo3 front-end user is therefore available as:

{{ store.typo3.feUser }}

Example

The following block shows an example of a QFQ report.

10.sql selects all users who have been assigned files in our file tracker.

10.10 then selects all files belonging to this user, prints the username as header and then displays the files in a nice table with links to the files.

10.sql = SELECT assigned_to AS _user FROM FileTracker
            WHERE assigned_to IS NOT NULL
            GROUP BY _user
            ORDER BY _user

10.10.sql = SELECT id, path_scan FROM FileTracker
WHERE assigned_to = '{{user:R}}'
10.10.twig = <h2>{{ store.record.user }}</h2>
<table class="table table-hover tablesorter" id="{{pageAlias:T}}-twig">
  <thead><tr><th>ID</th><th>File</th></tr></thead>
  <tbody>
  {% for row in result %}
    <tr>
      <td>{{ row.id }}</td>
      <td>{{ ("d:|M:pdf|s|t:"~ row.path_scan ~"|F:" ~ row.path_scan ) | qfqlink }}</td>
    </tr>
  {% endfor %}
  </tbody>
</table>

Debug the bodytext

The parsed bodytext could be displayed by activating 'showDebugInfo' (:ref:`debug`) and specifying:

debugShowBodyText = 1

A small symbol with a tooltip will be shown, where the content record will be displayed on the webpage. Note: :ref:`debug` information will only be shown with showDebugInfo: yes in :ref:`configuration`.

Inline Report editing

For quick changes it can be bothersome to go to the TYPO3 backend to update the page content and reload the page. For this reason, QFQ offers an inline report editing feature whenever there is a TYPO3 BE user logged in. A small link symbol will appear on the right-hand side of each report record. Please note that the TYPO3 Frontend cache is also deleted upon each inline report save.

In order for the inline report editing to work, QFQ needs to be able to access the T3 database. This database is assumed to be accessible with the same credentials as specified with indexQfq.

Structure

A report can be divided into several levels. This can make report definitions more readable because it allows for splitting of otherwise excessively long SQL queries. For example, if your SQL query on the root level selects a number of person records from your person table, you can use the SQL query on the second level to look up the city where each person lives.

See the example below:

10.sql = SELECT id AS _pId, CONCAT(firstName, " ", lastName, " ") AS name FROM Person
10.rsep = <br>

10.10.sql = SELECT CONCAT(postal_code, " ", city) FROM Address WHERE pId = {{10.pId}}
10.10.rbeg = (
10.10.rend = )

This would result in:

John Doe (3004 Bern)
Jane Miller (8008 Zürich)
Frank Star (3012 Bern)

Text across several lines

To get better human readable SQL queries, it's possible to split a line across several lines. Lines with keywords are on their own (:ref:`QFQ Keywords (Bodytext)<qfq_keywords>` start a new line). If a line is not a 'keyword' line, it will be appended to the last keyword line. 'Keyword' lines are detected on:

• <level>.<keyword> =
• {
• <level>[.<sub level] {

Example:

10.sql = SELECT 'hello world'
           FROM Mastertable
10.tail = End

20.sql = SELECT 'a warm welcome'
           'some additional', 'columns'
           FROM AnotherTable
           WHERE id>100

20.head = <h3>
20.tail = </h3>

Join mode: SQL

This is the default. All lines are joined with a space in between. E.g.:

10.sql = SELECT 'hello world'
           FROM Mastertable

Results to: 10.sql = SELECT 'hello world' FROM Mastertable

Notice the space between "...world'" and "FROM ...".

Join mode: strip whitespace

Ending a line with a \ strips all leading and trailing whitespaces of that line joins the line directly (no extra space in between). E.g.:

10.sql = SELECT 'hello world', 'd:final.pdf \
                                |p:id=export  \
                                |t:Download' AS _pdf \

Results to: 10.sql = SELECT 'hello world', 'd:final.pdf|p:id=export|t:Download' AS _pdf

Note: the \ does not force the joining, it only removes the whitespaces.

To get the same result, the following is also possible:

10.sql = SELECT 'hello world', CONCAT('d:final.pdf'
                                '|p:id=export',
                                '|t:Download') AS _pdf

Nesting of levels

Levels can be nested. E.g.:

10 {
  sql = SELECT ...
  5 {
      sql = SELECT ...
      head = ...
  }
}

This is equal to:

10.sql = SELECT ...
10.5.sql = SELECT ...
10.5.head = ...

Leading / trailing spaces

By default, leading or trailing whitespaces are removed from strings behind '='. E.g. 'rend = test ' becomes 'test' for rend. To prevent any leading or trailing spaces, surround them by using single or double ticks. Example:

10.sql = SELECT name FROM Person
10.rsep = ' '
10.head = "Names: "

Braces character for nesting

By default, curly braces '{}' are used for nesting. Alternatively angle braces '<>', round braces '()' or square braces '[]' are also possible. To define the braces to use, the first line of the bodytext has to be a comment line and the last character of that line must be one of '{[(<'. The corresponding braces are used for that QFQ record. E.g.:

# Specific code. >
10 <
  sql = SELECT
  head = <script>
         data = [
           {
             10, 20
           }
         ]
         </script>
>

Per QFQ tt-content record, only one type of nesting braces can be used.

Be careful to:

• write nothing else than whitespaces/newline behind an open brace

• the closing brace has to be alone on a line:

  10.sql = SELECT 'Yearly Report'
  
  20 {
        sql = SELECT companyName FROM Company LIMIT 1
        head = <h1>
        tail = </h1>
  }
  
  30 {
        sql = SELECT depName FROM Department
        head = <p>
        tail = </p>
        5 {
              sql = SELECT 'detailed information for department'
              1.sql = SELECT name FROM Person LIMIT 7
              1.head = Employees:
        }
  }
  
  30.5.tail = More will follow
  
  50
  
  {
         sql = SELECT 'A query with braces on their own'
  }

Access column values

Columns of the upper / outer level result can be accessed via variables in two ways

• STORE_RECORD: {{pId:R}}
• Level Key: {{10.pId}}

The STORE_RECORD will always be merged with previous content. The Level Keys are unique.

Important

Multiple columns, with the same column name, can't be accessed individually. Only the last column is available.

Important

Retrieving the final value of :ref:`special-column-names` is possible via '{{&<column>:R}} (there is an '&' direct behind '{{')

Example:

10.sql = SELECT 'p:home&form=Person|s|b:success|t:Edit' AS _link
10.20.sql = SELECT '{{link:R}}', '{{&link:R}}'

The first column of row 10.20 returns p:home&form=Person|s|b:success|t:Edit,the second column returns '<span class="btn btn-success"><a href="?home&s=badcaffee1234">Edit</a></span>'.

Example STORE_RECORD:

10.sql= SELECT p.id AS _pId, p.name FROM Person AS p
10.5.sql = SELECT adr.city, 'dummy' AS _pId FROM Address AS adr WHERE adr.pId={{pId:R}}
10.5.20.sql = SELECT '{{pId:R}}'
10.10.sql = SELECT '{{pId:R}}'

The line '10.10' will output 'dummy' in cases where there is at least one corresponding address. If there are no addresses (all persons) it reports the person id. If there is at least one address, it reports 'dummy', cause that's the last stored content.

Example 'level':

10.sql= SELECT p.id AS _pId, p.name FROM Person AS p
10.5.sql = SELECT adr.city, 'dummy' AS _pId FROM Address AS adr WHERE adr.pId={{10.pId}}
10.5.20.sql = SELECT '{{10.pId}}'
10.10.sql = SELECT '{{10.pId}}'

Notes to the level:

Levels	A report is divided into levels. The Example has levels 10, 20, 30, 30.5, 30.5.1, 50
Qualifier	A level is divided into qualifiers 30.5.1 has 3 qualifiers 30, 5, 1
Root levels	Is a level with one qualifier. E.g.: 10
Sub levels	Is a level with more than one qualifier. E.g. levels 30.5 or 30.5.1
Child	The level 30 has one child and child child: 30.5 and 30.5.1
Example	10, 20, 30, 50* are root level and will be completely processed one after each other. 30.5 will be executed as many times as 30 has row numbers. 30.5.1 will be executed as many times as 30.5 has row numbers.

Report Example 1:

# Displays current date
10.sql = SELECT CURDATE()

# Show all students from the person table
20.sql = SELECT p.id AS pId, p.firstName, " - ", p.lastName FROM Person AS p WHERE p.typ LIKE "student"

# Show all the marks from the current student ordered chronological
20.25.sql = SELECT e.mark FROM Exam AS e WHERE e.pId={{20.pId}} ORDER BY e.date

# This query will never be fired, cause there is no direct parent called 20.30.
20.30.10.sql = SELECT 'never fired'

Wrapping rows and columns: Level

Order and nesting of queries, will be defined with a TypoScript-alike syntax:

level.sublevel1.subsublevel2. ...

• Each 'level' directive needs a final key, e.g: 20.30.10. sql.
• A key sql is necessary in order to process a level.

See all :ref:`QFQ Keywords (Bodytext)<qfq_keywords>`.

Processing of columns in the SQL result

• The content of all columns of all rows will be printed sequentially, without separator (except one is defined).
• Rows with :ref:`special-column-names` will be rendered internally by QFQ and the QFQ output of such processing (if there is any) is taken as the content.

Special column names

Note

Twig: respect that the 'special column name'-columns are rendered before Twig becomes active. The recommended way by using Twig is not to use special column names at all. Use the Twig version qfqLink.

QFQ don't care about the content of any SQL-Query - it just copy the content to the output (=Browser).

One exception are columns, whose name starts with '_'. E.g.:

10.sql = SELECT 'All', 'cats' AS red, 'are' AS _green, 'grey in the night' AS _link

• The first and second column are regular columns. No QFQ processing.

• The third column (alias name 'green') is no QFQ special column name, but has an '_' at the beginning: this column content will be hidden.

• The fourth column (alias name 'link') uses a QFQ special column name. Here, only in this example, it has no further meaning.

• All columns in a row, with the same special column name (e.g. ... AS _page) will have the same column name: 'page'. To access individual columns a uniq column title is necessary and can be added ...|column1:

  10.sql = SELECT '..1..' AS '_page|column1', '..2..' AS '_page|column2'

  Those columns can be accessed via {{column1:R}} , {{column2:R}} (recommended) or {{10.column1}} , {{10.column2}}.

• To skip wrapping via fbeg, fsep, fend for dedicated columns, add the keyword |_noWrap to the column alias. Example:

  10.sql = SELECT 'world' AS 'title|_noWrap'

Summary:

Note

• For 'special column names': the column name together with the value controls how QFQ processes the column.
• Special column names always start with '_'.
• Important: to reference a column, the name has to be given without '_'. E.g. SELECT 'cat' AS _pet will be used with {{pet:R}} (notice the missing '_').
• Columns starting with a '_' but not defined as as QFQ special column name are hidden(!) - in other words: they are not printed as output.
• Tip: if a column name starts with '_' the column name becomes '_....' - which will be hidden! To be safe: always define an alias!
• Access to 'hidden' columns via {{<level>.<column>}} or {{<column>:R}} are possible and often used.

Reserved column name	Purpose
_link	:ref:`column-link` - Build links with different features.
_pageX or _PageX	:ref:`column_pageX` - Shortcut version of the link interface for fast creation of internal links. The column name is composed of the string page/Page and a optional character to specify the type of the link.
_download	:ref:`download` - single file (any type) or concatenate multiple files (PDF, ZIP)
_pdf, _file, _zip _Pdf, _File, _Zip	:ref:`column_pdf` - Shortcut version of the link interface for fast creation of :ref:`download` links. Used to offer single file download or to concatenate several PDFs and printout of websites to one PDF file.
_savePdf	:ref:`column-save-pdf` - pre render PDF files
_excel	:ref:`excel-export` - creates Excel exports based on QFQ Report queries, optional with pre uploaded Excel template files
_yank	:ref:`copyToClipboard`. Shortcut version of the link interface
_mailto	:ref:`column_mailto` - Build email links. A click on the link will open the default mailer. The address is encrypted via JS against email bots.
_sendmail	:ref:`column_sendmail` - Send emails.
_exec	:ref:`column_exec` - Run batch files or executables on the webserver.
_script	:ref:`column_script` - Run php function defined in an external script

_mimeType	Show mime type of a given file
_thumbnail	:ref:`thumbnail<thumbnail>` - Create thumbnails on the fly. See :ref:`column-thumbnail`.
_monitor	:ref:`column-monitor` - Constantly display a file. See :ref:`column-monitor`.
_XLS	Used for Excel export. Append a newline character at the end of the string. Token must be part of string. See :ref:`excel-export`.
_XLSs	Used for Excel export. Prepend the token 's=' and append a newline character at the string. See :ref:`excel-export`.
_XLSb	Used for Excel export. Like '_XLSs' but encode the string base64. See :ref:`excel-export`.
_XLSn	Used for Excel export. Prepend 'n=' and append a newline character around the string. See :ref:`excel-export`.
_noWrap	Skip wrapping via fbeg, fsep, fend.
_hide	Hide a column with a special column name (like ... AS _link). Note: regular columns should be hidden by using '_' as the first letter of the column name.
_+<html-tag attributes>	The content will be wrapped with '<html-tag attributes>'. Example: SELECT 'example' AS '_+a href="http://example.com"' creates '<a href="http://example.com">example</a>'
_=<varname>	The content will be saved in store 'user' under 'varname'. Retrieve it later via {{varname:U}}. Example: 'SELECT "Hello world" AS _=text'. See :ref:`STORE_USER`, :ref:`store_user_examples`
_<nonReservedName>	Suppress output. Column names with leading underscore are used to select data from the database and make it available in other parts of the report without generating any output.
_formJson	System internal. Return form with given id as json string. (SELECT 'fid:<formId>[|reduce][|b64]' AS _formJson). Flag reduce filters out 'modified', 'created' as well as keys which hold default values. Flag b64 encodes the json string in base 64.

Column: _link

• Most URLs will be rendered via class link.
• Column names like _pagee`, ``_mailto, ... are wrapper to class link.
• The parameters for link contains a prefix to make them position-independent.
• Parameter have to be separated with '|'. If '|' is part of the value, it needs to be escaped '\|'. This can be done via QFQ SQL function QBAR() - see :ref:`qbar-escape-qfq-delimiter`.

Render mode

The following table might be hard to read - but it's really useful to understand. It solves a lot of different situations. If there are no special condition (like missing value, or suppressed links), render mode 0 is sufficient. But if the URL text is missing, or the URL is missing, OR the link should be rendered in sql row 1-10, but not 5, then render mode might dynamically control the rendered link.

• Column Mode is the render mode and controls how the link is rendered.

Mode	Given: url & text	Given: only url	Given: only text	Description
0 (default)	<a href=url>text</a>	<a href=url>url</a>		text or image will be shown, only if there is a url, page or mailto
1	<a href=url>text</a>	<a href=url>url</a>	text	text or image will be shown, independently of whether there is a url or not
2	<a href=url>text</a>			no link if text is empty
3	text	url	text	no link, only text or image, incl. Optional tooltip. For Bootstrap buttons r:3 will set the button to disable and no link/sip is rendered.
4	url	url	text	no link, show text, if text is empty, show url, incl. optional tooltip
5				nothing at all
6	pure text		pure text	no link, pure text
7	pure url	pure url		no link, pure url
8	pure sip	pure sip		no link, no html, only the 13 digit sip code.

Example:

10.sql = SELECT CONCAT('u:', p.homepage, IF(p.showHomepage='yes', '|r:0', '|r:5') ) AS _link FROM Person AS p

Tip:

An easy way to switch between different options of rendering a link, incl. Bootstrap buttons, is to use the render mode.

• no render mode or 'r:0' - the full functional link/button.
• 'r:3' - the link/button is rendered with text/image/glyph/tooltip ... but without a HTML a-tag! For Bootstrap button, the button get the 'disabled' class.
• 'r:5' - no link/button at all.

Alert: Question

Syntax

q[:<alert text>[:<level>[:<positive button text>[:<negative button text>[:<timeout>[:<flag modal>]]]]]]

• If a user clicks on a link, an alert is shown. If the user answers the alert by clicking on the 'positive button', the browser opens the specified link. If the user click on the negative answer (or waits for timout), the alert is closed and the browser does nothing.
• All parameter are optional.
• Parameter are separated by ':'
• To use ':' inside the text, the colon has to be escaped by \. E.g. 'ok\ : I understand'.

Parameter	Description
Text	The text shown by the alert. HTML is allowed to format the text. Any ':' needs to be escaped. Default: 'Please confirm'.
Level	success, info, warning, danger
Positive button text	Default: 'Ok'
Negative button text	Default: 'Cancel'. To hide the second button: '-'
Timeout in seconds	0: no timeout, >0: after the specified time in seconds, the alert will dissapear and behaves like 'negative answer'
Flag modal	0: Alert behaves not modal. 1: (default) Alert behaves modal.

Examples:

SQL-Query	Result
SELECT "p:form_person|q:Edit Person:warn" AS _link	Shows alert with level 'warn'
SELECT "p:form_person|q:Edit Person::I do:No way" AS _link	Instead of 'Ok' and 'Cancel', the button text will be 'I do' and 'No way'
SELECT "p:form_person|q:Edit Person:::10" AS _link	The Alert will be shown 10 seconds
SELECT "p:form_person|q:Edit Person:::10:0" AS _link	The Alert will be shown 10 seconds and is not modal.

Columns: _page[X]

The colum name is composed of the string page and a trailing character to specify the type of the link.

Syntax:

10.sql = SELECT "[options]" AS _page[<link type>]

with: [options] = [p:<page & param>][|t:<text>][|o:<tooltip>][|q:<question parameter>][|c:<class>][|g:<target>][|r:<render mode>]

Column: _paged

These column offers a link, with a confirmation question, to delete one record (mode 'table') or a bunch of records (mode 'form'). After deleting the record(s), the current page will be reloaded in the browser.

Syntax

10.sql = SELECT "U:table=<tablename>&r=<record id>|q:<question>|..." AS _paged
10.sql = SELECT "U:form=<formname>&r=<record id>|q:<question>|..." AS _paged

If the record to delete contains column(s), whose column name match on %pathFileName% and such a column points to a real existing file, such a file will be deleted too. If the table contains records where the specific file is multiple times referenced, than the file is not deleted (it would break the still existing references). Multiple references are not found, if they use different colummnnames or tablenames.

Mode: table

• table=<table name>
• r=<record id>

Deletes the record with id '<record id>' from table '<table name>'.

Mode: form

• form=<form name>
• r=<record id>

Deletes the record with id '<record id>' from the table specified in form '<form name>' as primary table. Additional action FormElement of type beforeDelete or afterDelete will be fired too.

Examples

10.sql = SELECT 'U:table=Person&r=123|q:Do you want delete John Doe?' AS _paged
10.sql = SELECT 'U:form=person-main&r=123|q:Do you want delete John Doe?' AS _paged

Columns: _Page[X]

• Similar to _page[X]
• Parameter are position dependent and therefore without a qualifier!

"[<page id|alias>[&param=value&...]] | [text] | [tooltip] | [question parameter] | [class] | [target] | [render mode]" as _Pagee.

Column: _Paged

• Similar to _paged
• Parameter are position dependent and therefore without a qualifier!

"[table=<table name>&r=<record id>[&param=value&...] | [text] | [tooltip] | [question parameter] | [class] | [render mode]" as _Paged.
"[form=<form name>&r=<record id>[&param=value&...] | [text] | [tooltip] | [question parameter] | [class] | [render mode]" as _Paged.

Column: _vertical

Use instead :ref:`vertical-column-title`

Warning

The '... AS _vertical' is deprecated - do not use it anymore.

Render text vertically. This is useful for tables with limited column width. The vertical rendering is achieved via CSS tranformations (rotation) defined in the style attribute of the wrapping tag. You can optionally specify the rotation angle.

Syntax

10.sql = SELECT "<text>|[<angle>]" AS _vertical

Parameter	Description	Default value
<text>	The string that should be rendered vertically.	none
<angle>	How many degrees should the text be rotated? The angle is measured clockwise from baseline of the text.	270

The text is surrounded by some HTML tags in an effort to make other elements position appropriately around it. This works best for angles close to 270 or 90.

Minimal Example

10.sql = SELECT "Hello" AS _vertical
20.sql = SELECT "Hello|90" AS _vertical
20.sql = SELECT "Hello|-75" AS _vertical

Column: _mailto

Easily create Email links.

Syntax

10.sql = SELECT "<email address>|[<link text>]" AS _mailto

Parameter	Description	Default value
<emailaddress>	The email address where the link should point to.	none
<linktext>	The text that should be displayed on the website and be linked to the email address. This will typically be the name of the recipient. If this parameter is omitted, the email address will be displayed as link text.	none

Minimal Example

10.sql = SELECT "john.doe@example.com" AS _mailto

Advanced Example

10.sql = SELECT "john.doe@example.com|John Doe" AS _mailto

Column: _sendmail

Format:

t:<TO:email[,email]>|f:<FROM:email>|s:<subject>|b:<body>
    [|c:<CC:email[,email]]>[|B:<BCC:email[,email]]>[|r:<REPLY-TO:email>]

E	encode|decode|none	Body: will be htmlspecialchar() encoded, decoded (default) or none (untouched).
mode	html	Body: will be send as a HTML mail.

• e|E: By default, QFQ stores values 'htmlspecialchars()' encoded. If such values have to send by email, the html entities are unwanted. Therefore the default setting for 'subject' und 'body' is to decode the values via 'htmlspecialchars_decode()'. If this is not wished, it can be turned off by e=none and/or E=none.

Minimal Example

10.sql = SELECT "t:john.doe@example.com|f:company@example.com|s:Latest News|b:The new version is now available." AS _sendmail

This will send an email with subject Latest News from company@example.com to john.doe@example.com.

This will send an email with subject Latest News from company@example.com to customer1, customer2 and customer3 by using a realname for customer2 and customer3 and suppress generating of OoO answer if any receiver is on vacation. Additional the CEO as well as backup will receive the mail via CC and BCC.

For debugging, please check :ref:`REDIRECT_ALL_MAIL_TO`.

Column: _script

Run a php function defined in an external script.

• All column parameters are passed as an associative array to the function as the first argument.
• The second argument (here called $qfq) is an object which acts as an interface to QFQ functionality (see below).

• The current working directory inside the function is the current web instance (e.g. location of index.php).

  • Hint: Inside the script dirname(__FILE__) gives the path of the script.

      • string $useStores: are the stores in which variable is searched (in order from left to right). see :ref:`store`.
      • string $sanitizeClass: (see :ref:`sanitize-class`)
      • string $foundInStore: is filled with the name of the store in which the variable was found.

      • string $typeMessageViolate: defines what to return if the sanitize class was violated:

        • 'c' : returns '!!<sanitize class>!!'
        • '0' : returns '0'
        • 'e' : returns ''

    • return string|false:

• For column _zip, an optional parameter might define the path and filename inside the ZIP: F:<orig filename>:<inside ZIP path and filename>

• To only render the page content without menus add the parameter type=2. For example: U:id=pageToPrint&type=2&_sip=1&r=', r.id

• Example:

  # ... AS _file
  10.sql = SELECT "F:fileadmin/test.pdf" as _pdf
  20.sql = SELECT "p:id=export&r=1" as _pdf
  30.sql = SELECT "t:Download PDF|F:fileadmin/test.pdf" as _pdf
  40.sql = SELECT "t:Download PDF|p:id=export&r=1" as _pdf
  50.sql = SELECT "d:complete.pdf|t:Download PDF|F:fileadmin/test1.pdf|F:fileadmin/test2.pdf" as _pdf
  60.sql = SELECT "d:complete.pdf|t:Download PDF|F:fileadmin/test.pdf|p:id=export&r=1|u:www.example.com" AS _pdf
  
  # ... AS _file
  100.sql = SELECT "F:fileadmin/test.pdf" as _file
  110.sql = SELECT "p:id=export&r=1" as _file
  120.sql = SELECT "t:Download PDF|F:fileadmin/test.pdf" as _file
  130.sql = SELECT "t:Download PDF|p:id=export&r=1" as _file
  
  # ... AS _zip
  200.sql = SELECT "F:fileadmin/test.pdf" as _zip
  210.sql = SELECT "p:id=export&r=1" as _zip
  220.sql = SELECT "t:Download ZIP|F:fileadmin/test.pdf" as _zip
  230.sql = SELECT "t:Download ZIP|p:id=export&r=1" as _zip
  # Several files
  240.sql = SELECT "d:complete.zip|t:Download ZIP|F:fileadmin/test1.pdf|F:fileadmin/test2.pdf" as _zip
  # Several files with new path/filename
  250.sql = SELECT "d:complete.zip|t:Download ZIP|F:fileadmin/test1.pdf:data/file-1.pdf|F:fileadmin/test2.pdf:data/file-2.pdf" as _zip

Column: _savePdf

Generated PDFs can be stored directly on the server with this functionality. The link query consists of the following parameters:

• One or more element sources (such as F:, U:, p:, see :ref:`download-parameter-files`), including possible wkhtmltopdf parameters
• The export filename and path as d: - for security reasons, this path has to start with fileadmin/ and end with .pdf.

Tips:

• Please note that this option does not render anything in the front end, but is executed each time it is parsed. You may want to add a check to prevent multiple execution.
• It is not advised to generate the filename with user input for security reasons.
• If the target file already exists it will be overwriten. To save individual files, choose a new filename, for example by adding a timestamp.

Example:

SELECT "d:fileadmin/result.pdf|F:fileadmin/_temp_/test.pdf" AS _savePdf
SELECT "d:fileadmin/result.pdf|F:fileadmin/_temp_/test.pdf|U:id=test&--orientation=landscape" AS _savePdf

Column: _thumbnail

For file T:<pathFileName> a thumbnail will be rendered, saved (to be reused) and a HTML <img> tag is returned, With the SIP encoded thumbnail.

The thumbnail:

• Size is specified via W:<dimension>. The file is only rendered once and subsequent access is delivered via a local QFQ cache.
• Will be rendered, if the source file is newer than the thumbnail or if the thumbnail dimension changes.
• The caching is done by building the MD5 of pathFileName and thumbnail dimension.
• Of multi page files like PDFs, the first page is used as the thumbnail.

All file formats, which 'convert' ImageMagick (https://www.imagemagick.org/) supports, can be used. Office file formats are not supported. Due to speed and quality reasons, SVG files will be converted by inkscape. If a file format is not known, QFQ tries to show a corresponding file type image provided by Typo3 - such an image is not scaled.

In :ref:`configuration` the exact location of convert and inkscape can be configured (optional) as well as the directory names for the cached thumbnails.

Token	Example	Comment
T	T:fileadmin/file3.pdf	File render a thumbnail
W	W:200x, W:x100, W:200x100	Dimension of the thumbnail: '<width>x<height>. Both parameter are otional. If non is given the default is W:150x
s	s:1, s:0	Optional. Default: s:1. If SIP is enabled, the rendered URL is a link via api/download.php?... Else a direct pathFileName.
r	r:7	Render Mode. Default 'r:0'. With 'r:7' only the url will be delivered.

The render mode '7' is useful, if the URL of the thumbnail have to be used in another way than the provided html-'<img>' tag. Something like <body style="background-image:url(bgimage.jpg)"> could be solved with SELECT "<body style="background-image:url(", 'T:fileadmin/file3.pdf' AS _thumbnail, ')">'

Example:

# SIP protected, IMG tag, thumbnail width 150px
10.sql = SELECT 'T:fileadmin/file3.pdf' AS _thumbnail

# SIP protected, IMG tag, thumbnail width 50px
20.sql = SELECT 'T:fileadmin/file3.pdf|W:50' AS _thumbnail

# No SIP protection, IMG tag, thumbnail width 150px
30.sql = SELECT 'T:fileadmin/file3.pdf|s:0' AS _thumbnail

# SIP protected, only the URL to the image, thumbnail width 150px
40.sql = SELECT 'T:fileadmin/file3.pdf|s:1|r:7' AS _thumbnail

Dimension

ImageMagick support various settings to force the thumbnail size. See https://www.imagemagick.org/script/command-line-processing.php#geometry or http://www.graphicsmagick.org/GraphicsMagick.html#details-geometry.

Cleaning

By default, the thumbnail directories are never cleaned. It's a good idea to install a cronjob which purges all files older than 1 year:

find /path/to/files -type f -mtime +365 -delete

Render

Public thumbnails are rendered at the time when the T3 QFQ record is executed. Secure thumbnails are rendered when the 'download.php?s=...' is called. The difference is, that the 'public' thumbnails blocks the page load until all thumbnails are rendered, instead the secure thumbnails are loaded asynchonous via the browser - the main page is already delivered to browser, all thumbnails appearing after a time.

A way to pre render thumbnails, is a periodically called (hidden) T3 page, which iterates over all new uploaded files and triggers the rendering via column _thumbnail.

Thumbnail: secure

Mode 'secure' is activated via enabling SIP (s:1, default). The thumbnail is saved under the path thumbnailDirSecure as configured in :ref:`configuration`.

The secure path needs to be protected against direct file access by the webmaster / webserver configuration too.

QFQ returns a HTML 'img'-tag:

<img src="api/download.php?s=badcaffee1234">

Thumbnail: public

Mode 'public' has to be explicit activated by specifying s:0. The thumbnail is saved under the path thumbnailDirPublic as configured in :ref:`configuration`.

QFQ returns a HTML 'img'-tag:

<img src="{{thumbnailDirPublic:Y}}/<md5 hash>.png">

Column: _monitor

Detailed explanation: :ref:`monitor`

Syntax

10.sql = SELECT 'file:<filename>|tail:<number of last lines>|append:<0 or 1>|interval:<time in ms>|htmlId:<id>' AS _monitor

Parameter	Description	Default value/behaviour
<filename>	The path to the file. Relative to T3 installation directory or absolute.	none
<tail>	Number of last lines to show	30
<append>	0: Retrieved content replaces current. 1: Retrieved content will be added to current.	0
<htmlId>	Reference to HTML element to whose content replaced by the retrieve one.	monitor-1

Copy to clipboard

Token	Example	Comment
y[:<content>]	y, y:some content	Initiates 'copy to clipboard' mode. Source might given text or page or url
F:<pathFileName>	F:fileadmin/protected/data.R	pathFileName in DocumentRoot

Example:

10.sql = SELECT 'y:hello world (yank)|t:content direct (yank)' AS _yank
                , 'y:hello world (link)|t:content direct (link)' AS _link
                , CONCAT('F:', p.pathFileName,'|t:File (yank)|o:', p.pathFileName) AS _yank
                , CONCAT('y|F:', p.pathFileName,'|t:File (link)|o:', p.pathFileName) AS _link
            FROM Person AS p

API Call QFQ Report (e.g. AJAX)

Note

QFQ Report functionality protected by SIP offered to simple API calls: typo3conf/ext/qfq/Classes/Api/dataReport.php?s=....

• General use API call to fire a specific QFQ tt-content record. Useful for e.g. AJAX calls. No Typo3 is involved. No FE-Group access control.
• This defines just a simple API endpoint. For defining a rest API see: :ref:`restApi`.

• Custom response headers can be defined by setting the variable apiResponseHeader in the record store.

  • Multiple headers should be separated by n or rn. e.g.: Content-Type: application/jsonncustom-header: fooBar

• If the api call succeeds the rendered content of the report is returned as is. (no additional formatting, no JSON encoding)

  • You can use MYSQL to create Json. See: MYSQL create Json and MariaDB Json functions

• If a QFQ error occurs then a http-status of 400 is returned together with a JSON encoded response of the form: {"status":"error", "message":"..."}

Example QFQ record JS (with tt_content.uid=12345):

5.sql = SELECT "See console log for output"

# Register SIP with given arguments.
10.sql = SELECT 'U:uid=12345&arg1=Hello&arg2=World|s|r:8' AS '_link|col1|_hide'

# Build JS
10.tail = <script>
    console.log('start api request');
    $.ajax({
    url: 'typo3conf/ext/qfq/Classes/Api/dataReport.php?s={{&col1:RE}}',
    data: {arg3:456, arg4:567},
    method: 'POST',
    dataType: 'TEXT',
    success: function(response, status, jqxhr) {console.log(response); console.log(jqxhr.getAllResponseHeaders());},
    error: function(jqXHR, textStatus, errorThrown) {console.log(jqXHR.responseText, textStatus, errorThrown);}
    });
  </script>

Example QFQ record called by above AJAX:

# Create a dedicated tt-content record (on any T3 page, might be on the same page as the JS code).
# The example above assumes that this record has the tt_content.uid=12345.
render = api
10.sql = SELECT '{{arg1:S}} {{arg2:S}} {{arg3:C}} {{arg4:C}}', NOW()
, 'Content-Type: application/json\ncustom-header: fooBar' AS _apiResponseHeader

Example text returned by the above AJAX call:

Hello World 456 5672020-09-22 18:09:47

REST Client

Note

POST and GET data to external REST interfaces or other API services.

Access to external services via HTTP / HTTPS is triggered via special column name restClient. The received data might be processed in subsequent calls.

Example:

# Retrieve information. Received data is delivered in JSON and decoded / copied on the fly to CLIENT store (CLIENT store is emptied beforehand)
10.sql = SELECT 'n:https://www.dummy.ord/rest/person/id/123' AS _restClient
20.sql = SELECT 'Status: {{http-status:C}}<br>Name: {{name:C:alnumx}}<br>Surname: {{surname:C:alnumx}}'

# Simple POST request via https. Result is printed on the page.
10.sql = SELECT 'n:https://www.dummy.ord/rest/person/id/123|method:POST|content:{"name":"John";"surname":"Doe"}' AS _restClient

Token	Example | Comment
n	n:https://www.dummy.ord/rest/person |
method	method:POST		GET, POST, PUT or DELETE
content	content:{"name":"John";"surname":"Doe"}		Depending on the REST server JSON might be expected
header	see below
timeout	timeout:5		Default: 5 seconds.

Header

• Each header must be separated by \r\n or n.
• An explicit given header will overwrite the named default header.
• Default header:
  • content-type: application/json - if content starts with a {.
  • content-type: text/plain - if content does not start with a {.
  • connection: close - Necessary for HTTP 1.1.

Result received

• After a REST client call is fired, QFQ will wait up to timeout seconds for the answer.
• By default, the whole received answer will be shown. To suppress the output: ... AS '_restClient|_hide'
• The variable {{http-status:C}} shows the `HTTP status code<https://en.wikipedia.org/wiki/List_of_HTTP_status_codes>`_. A value starting with '2..' shows success.
• In case of an error, {{error-message:C:allbut}} shows some details.

• In case the returned answer is a valid JSON string, it is flattened and automatically copied to STORE_CLIENT with corresponding key names.

  • NOTE: The CLIENT store is emptied beforehand!

JSON answer example:

Answer from Server:  { 'name' : 'John', 'address' : {'city' : 'Bern'} }
Retrieve the values via:  {{name:C:alnumx}}, {{city:C:alnumx}}

Special SQL Functions (prepared statements)

QBAR: Escape QFQ Delimiter

The SQL function QBAR(text) replaces "|" with "\|" in text to prevent conflicts with the QFQ special column notation. In general this function should be used when there is a chance that unplanned '|'-characters occur.

Example:

10.sql = SELECT CONCAT('p:notes|t:Information: ', QBAR(Note.title), '|b') AS _link FROM Note

In case 'Note.title' contains a '|' (like 'fruit | numbers'), it will confuse the '... AS _link' class. Therefore it's necessary to 'escape' (adding a '' in front of the problematic character) the bar which is done by using QBAR().

QCC: Escape colon / coma

The SQL function QCC(text) replaces ":" with "\:" and "," with "\," in text to prevent conflicts with the QFQ notation.

QNL2BR: Convert newline to HTML '<br>'

The SQL function QNL2BR(text) replaces LF or CR/LF by <br>. This can be used for data (containing LF) to output on a HTML page with correctly displayed linefeed.

Example:

10.sql = SELECT QNL2BR(Note.title) FROM Note

One possibility how LF comes into the database is with form elements of type textarea if the user presses enter inside.

QMORE: Truncate Long Text - more/less

The SQL function QMORE(text, n) truncates text if it is longer than n characters and adds a "more.." button. If the "more..." button is clicked, the whole text is displayed. The stored procedure QMORE() will inject some HTML/CSS code.

Example:

10.sql = SELECT QMORE("This is a text which is longer than 10 characters", 10)

Output:

This is a `more..`

QIFEMPTY: if empty show token

The SQL function QIFEMPTY(input, token) returns 'token' if 'input' is 'empty string' / '0' / '0000-00-00' / '0000-00-00 00:00:00'.

Example:

10.sql = SELECT QIFEMPTY('hello world','+'), QIFEMPTY('','-')

Output:

hello world-

QDATE_FORMAT: format a timestamp, show '-' if empty

The SQL function QDATE_FORMAT(timestamp) returns 'dd.mm.YYYY hh:mm', if 'timestamp' is 0 returns '-'

Example:

10.sql = SELECT QDATE_FORMAT( '2019-12-31 23:55:41' ), ' / ', QDATE_FORMAT( 0 ), ' / ', QDATE_FORMAT( '' )

Output:

31.12.2019 23:55 / - / -

QSLUGIFY: clean a string

Convert a string to only use alphanumerical characters and '-'. Characters with accent will be replaced without the accent. Non alphanumerical characters are stripped off. Spaces are replaced by '-'. All characters are lowercase.

Example:

10.sql = SELECT QSLUGIFY('abcd ABCD ae.ä.oe.ö.ue.ü z[]{}()<>.,?Z')

Output:

abcd-abcd-ae-a-oe-o-ue-u-z-z

strip_tags: strip html tags

The SQL function strip_tags(input) returns 'input' without any HTML tags.

Example:

10.sql = SELECT strip_tags('<a href="https://example.com"><b>my name</b> <i>is john</i></a> - end of sentence')

Output:

my name is john - end of sentence

QFQ Function

QFQ SQL reports can be reused, similar to a function in a regular programming language, including call parameter and return values.

• Per tt-content record the field 'subheader' (in Typo3 backend) defines the function name. The function can also referenced by using the tt-content number (uid) - but this is less readable.
• The calling report calls the function by defining <level>.function = <function name>(var1, var2, ...) => return1, return2, ...
• STORE_RECORD will be saved before calling the function and will be restored when the function has been finished.
• The function has only access to STORE_RECORD variables which has been explicitly defined in the braces (var1, var2, ...).
• The function return values will be copied to STORE_RECORD after the function finished.
• Inside the QFQ function, all other STORES are fully available.
• If <level>.function and <level>.sql are both given, <level>.function is processed first.
• If <level>.function is given, but <level>.sql not, the values of shead, stail, althead are even processed.
• If a function outputs something, this is not shown.
• The output of a QFQ function is accessible via {{_output:R}}.
• It is possible to call functions inside of a function.
• If render = api is defined in the function, both tt-content records can be saved on the same page and won't interfere.

Example tt-content record for the function:

Subheader: getFirstName
Code:
      #
      # {{pId:R}}
      #
      render = api

      100 {
        sql = SELECT p.firstName AS _firstName
                     , NOW() AS now, CONCAT('p:{{pageAlias:T}}&form=person&r=', p.id ) AS '_pagee|_hide|myLink'
                FROM Person AS p
                WHERE p.id={{pId:R}}
      }

Example tt-content record for the calling report:

#
# Example how to use `<level>.function = ...`
#

10 {
  sql = SELECT p.id AS _pId, p.name FROM Person AS p ORDER BY p.name
  head = <table class="table"><tr><th>Name</th><th>Firstname</th><th>Link (final)</th><th>Link (source)</th><th>NOW() (via Output)</th></tr>
  tail = </table>
  rbeg = <tr>
  renr = </tr>
  fbeg = <td>
  fend = </td>

  20 {
    function = getFirstName(pId) => firstName, myLink
  }

  30 {
    sql = SELECT '{{firstName:R}}', "{{myLink:R}}", "{{&myLink:R}}", '{{_output:R}}'
    fbeg = <td>
    fend = </td>
  }
}

Explanation:

• Level 10 iterates over all person.
• Level 10.20 calls QFQ function getFirstName() by delivering the pId via STORE_RECORD. The function expects the return value firstName and myLink.
• The function selects in level 100 the person given by {{pId:R}}. The firstName is not printed but a hidden column. Column now is printed. Column 'myLink' is a rendered link, but not printed.
• Level 10.30 prints the return values firstName and myLink (as rendered link and as source definition). The last column is the output of the function - the value of NOW()

If there are STORE_RECORD variables which can't be replaced: typically they have been not defined as function parameter or return values.

Download

Mode	Security	Note
Direct File access	Files are public available. No access restriction Pro: Simple, links can be copied. Con: Directory access, guess of filenames, only removing the file will deny access.	Use <a href="..."> Merge multiple sources: no but check :ref:`column-save-pdf` Custom 'save as filename': no

Secure Link	Default. SIP protected link. Pro: Parameter can't be altered, most easy definition in QFQ, access might be logged in user dependent. Cons: Links are assigned to a browser session and can't be copied	Use ..., 'd|F:file.pdf' AS _link Merge multiple sources: yes Custom 'save as filename': yes

The rest of this section applies only to Persistent Link and Secure Link. Download offers:

• Single file - download a single file (any type),
• PDF create - one or concatenate several files (uploaded) and/or web pages (=HTML to PDF) into one PDF output file,
• ZIP archive - filled with several files ('uploaded' or 'HTML to PDF'-converted).
• Excel - created from scratch or fill a template xlsx with database values.

By using the _link column name:

• the option d:... initiate creating the download link and optional specifies
  • in SIP mode: an export filename (),
  • in persistent link mode: path download script (optional) and key(s) to identify the record with the PathFilename information (see below).
• the optional M:... (Mode) specifies the export type (file, pdf, zip, export),
• the alttext a:... specifies a message in the download popup.

By using _pdf, _Pdf, _file, _File, _zip, _Zip, _excel as column name, the options d, M and s will be set.

All files will be read by PHP - therefore the directory might be protected against direct web access. This is the preferred option to offer secure downloads via QFQ. Check `secure-direct-file-access`_.

Parameter and (element) sources

• mode secure link (s:1) - download: d[:<exportFilename>]

  • exportFilename = <filename for save as> - Name, offered in the 'File save as' browser dialog. Default: 'output.<ext>'.

    If there is no exportFilename defined, then the original filename is taken (if there is one, else: output...).

    The user typically expects meaningful and distinct file names for different download links.

• mode persistent link (s:0) - download: d:[<path/name>]<key1>[/<keyN>]

  This setup is divided in part a) and b):

  Part a) - offering the download link.

  • The whole part a) is optional. The download itself will work without it.
  • (Optional) path/name = of the QFQ download.php script. By default``typo3conf/ext/qfq/Classes/Api/download.php``. Three further possibilities: dl.php or dl2.php or dl3.php (see below).
  • key1 = give a uniq identifier to select the wished record.

  Part b) - process the download

  • In the QFQ extension config: File > Query for direct download mode: download.php or dl.php or dl2.php or dl3.php up to 4 different SQL statements can be given with the regular QFQ download link syntax (skip the visual elements like button, text, glyph icon, question,...):

    SELECT CONCAT('d|F:', n.pathFileName) FROM Note AS n WHERE n.id=?

    All ? in the SQL statement will be replaced by the specified parameter. If there are more ? than parameter, the last parameter will be reused for all pending ?.

    E.g. 10.sql = SELECT 'd:1234|t:File.pdf' AS _link creates a link <a href="typo3conf/ext/qfq/Classes/Api/download.php/1234"><span class="btn btn-default">File.pdf</span></span>. If the user clicks on the link, QFQ will extract the 1234 argument and via download.php the query (defined in the Typo QFQ extension config) will be prepared and fires SELECT CONCAT('d|F:', n.pathFileName, '|t:File.pdf') FROM Note AS n WHERE n.id=1234. The download of the file, specified by n.pathFileName, will start.

    If no record ist selected, a custom error will be shown. If the query selectes more than one record, a general error will be shown.

    If one of dl.php or dl2.php or dl3.php should be used, please initially create the symlink(s), e.g. in the application directory (same level as typo3conf) ln -s typo3conf/ext/qfq/Classes/Api/download.php dl.php (or dl2.ph, dl3.php).

  Speaking URL)

  Instead of using a numeric value reference key, also a text can be used. Always take care that exactly one record is selected. The key is transferred by URL therefore untrusted: The sanitize class :ref:`alnumx<sanitize-class>` is applied. Example:

  Query: SELECT CONCAT('d|F:', n.pathFileName) FROM Person AS p WHERE p.name=? AND p.firstName=? AND p.publish='yes'
  Link:  https://example.com/dl.php/doe/john

• popupMessage: a:<text> - will be displayed in the popup window during download. If the creating/download is fast, the window might disappear quickly.

• mode: M:<mode>

  • mode = <file | pdf | zip | excel>
    • If M:file, the mime type is derived dynamically from the specified file. In this mode, only one element source is allowed per download link (no concatenation).
    • In case of multiple element sources, only pdf, zip and excel (template mode) is supported.
    • If M:zip is used together with p:..., U:... or u:.., those HTML pages will be converted to PDF. Those files get generic filenames inside the archive.
    • If not specified, the default 'Mode' depends on the number of specified element sources (=file or web page):
      • If only one file is specified, the default is file.
      • If there is a) a page defined or b) multiple elements, the default is pdf.

• element sources - for M:pdf or M:zip, all of the following element sources may be specified multiple times. Any combination and order of these options are allowed.

  • file: F:<pathFileName> - relative or absolute pathFileName offered for a) download (single), or to be concatenated in a PDF or ZIP.

  • page: p:id=<t3 page>&<key 1>=<value 1>&<key 2>=<value 2>&...&<key n>=<value n>.

    • By default, the options given to wkhtml will not be encoded by a SIP!

    • To encode the parameter via SIP: Add '_sip=1' to the URL GET parameter.

      E.g. p:id=form&_sip=1&form=Person&r=1.

      In that way, specific sources for the download might be SIP encrypted.

    • Any current HTML cookies will be forwarded to/via wkhtml. This includes the current FE Login as well as any QFQ session. Also the current User-Agent are faked via the wkhtml page request.

    • If there are trouble with accessing FE_GROUP protected content, please check :ref:`wkhtmltopdf<wkhtml>`.

  • url: u:<url> - any URL, pointing to an internal or external destination.

  • uid: uid:<function name> - the output is treated as HTML (will be converted to PDF) or EXCEL data.

    • The called tt-content record is identified by function name, specified in the subheader field. Optional the numeric id of the tt-content record (=uid) can be given.
    • Only the specified QFQ content record will be rendered, without any Typo3 layout elements (Menu, Body,...)
    • QFQ will retrieve the tt-content's bodytext from the Typo3 database, parse it, and render it as a PDF or Execl data.
    • Parameters can be passed: uid:<tt-content record id>[&arg1=value1][&arg2=value2][...] and will be available via STORE_SIP in the QFQ PageContent, or passed as wkhtmltopdf arguments, if applicable.
    • For more obviously structuring, put the additional tt-content record on the same Typo3 page (where the QFQ tt-content record is located which produces the link) and specify render = api (`report-render`_).

  • source: source:<function name>[&arg1=value1][&arg2=value2][&...] - (similar to a uid) the output is treated as further sources. Example result reported by function name might be: F:file.pdf1|uid:myData&arg=2|...

    • Use this functionality to define a central managed download function, which can be reused anywhere by just specify the function name and required arguments.
    • The called tt-content record is identified by function name, specified in the subheader field. Optional the numeric id of the tt-content record (=uid) can be given.
    • The output of the tt-content record will be treated as further source arguments. Nothing else than valid source references should be printed. Separate the references as usual by '|'.
    • The supplied arguments are available via STORE_SIP (this is different from qfq_function).
    • Tip: For more obviously structuring, put the additional tt-content record on the same Typo3 page (where the QFQ tt-content record is located which produces the link) and specify render = api (`report-render`_).

  • WKHTML Options for page, urlParam or url:

    • The 'HTML to PDF' will be done via wkhtmltopdf.
    • All possible options, suitable for wkhtmltopdf, can be submitted in the p:..., u:... or U:... element source. Check wkhtmltopdf.txt for possible options. Be aware that key/value tuple in the documentation is separated by a space, but to respect the QFQ key/value notation of URLs, the key/value tuple in p:..., u:... or U:... has to be separated by '='. Please see last example below.
    • If an option contains an '&' it must be escaped with double \ . See example.

  Most of the other Link-Class attributes can be used to customize the link as well.

Example _link:

# single `file`. Specifying a popup message window text is not necessary, cause a file directly accessed is fast.
SELECT "d:file.pdf|s|t:Download|F:fileadmin/pdf/test.pdf" AS _link

# single `file`, with mode
SELECT "d:file.pdf|M:pdf|s|t:Download|F:fileadmin/pdf/test.pdf" AS _link

# three sources: two pages and one file
SELECT "d:complete.pdf|s|t:Complete PDF|p:id=detail&r=1|p:id=detail2&r=1|F:fileadmin/pdf/test.pdf" AS _link

# three sources: two pages and one file
SELECT "d:complete.pdf|s|t:Complete PDF|p:id=detail&r=1|p:id=detail2&r=1|F:fileadmin/pdf/test.pdf" AS _link

# three sources: two pages and one file, parameter to wkhtml will be SIP encoded
SELECT "d:complete.pdf|s|t:Complete PDF|p:id=detail&r=1&_sip=1|p:id=detail2&r=1&_sip=1|F:fileadmin/pdf/test.pdf" AS _link

# three sources: two pages and one file, the second page will be in landscape and pagesize A3
SELECT "d:complete.pdf|s|t:Complete PDF|p:id=detail&r=1|p:id=detail2&r=1&--orientation=Landscape&--page-size=A3|F:fileadmin/pdf/test.pdf" AS _link

# One source and a header file. Note: the parameter to the header URL is escaped with double backslash.
SELECT "d:complete.pdf|s|t:Complete PDF|p:id=detail2&r=1&--orientation=Landscape&--header={{URL:R}}?indexp.php?id=head\\&L=1|F:fileadmin/pdf/test.pdf" AS _link

# One indirect source reference
SELECT "d:complete.pdf|s|t:Complete PDF|source:centralPdf&pId=1234" AS _link

  An additional tt-content record is defined with `sub header: centralPdf`. One or multiple attachments might be concatenated.
  10.sql = SELECT '|F:', a.pathFileName FROM Attachments AS a WHERE a.pId={{pId:S}}

Example _pdf, _zip:

# File 1: p:id=1&--orientation=Landscape&--page-size=A3
# File 2: p:id=form
# File 3: F:fileadmin/file.pdf
SELECT 't:PDF|a:Creating a new PDF|p:id=1&--orientation=Landscape&--page-size=A3|p:id=form|F:fileadmin/file.pdf' AS _pdf

# File 1: p:id=1
# File 2: u:http://www.example.com
# File 3: F:fileadmin/file.pdf
SELECT 't:PDF - 3 Files|a:Please be patient|p:id=1|u:http://www.example.com|F:fileadmin/file.pdf' AS _pdf

# File 1: p:id=1
# File 2: p:id=form
# File 3: F:fileadmin/file.pdf
SELECT CONCAT('t:ZIP - 3 Pages|a:Please be patient|p:id=1|p:id=form|F:', p.pathFileName) AS _zip
