Preparation

Report & Form
^^^^^^^^^^^^^

In PHP 5.x the QFQ extension needs  the PHP MySQL native driver. The following functions are used and are only available with the
native driver (see also: http://dev.mysql.com/downloads/connector/php-mysqlnd/):

* mysqli::get_result (important),
* mysqli::fetch_all (nice to use)

To normalize UTF8 input, the *php5-intl* resp. *php7.0-intl* package is needed by

* normalizer::normalize()

59
For the `download`_ function, the programs `pdftk` and `file` are necessary to concatenate PDF files.
60

61
62
Preparation for Ubuntu 14.04::

63
64
	sudo apt-get install php5-mysqlnd php5-intl
	sudo apt-get install pdftk file                # for file upload and PDF
65
66
67
	sudo php5enmod mysqlnd
	sudo service apache2 restart

Preparation for Ubuntu 16.04::
69

70
	sudo apt install php7.0-intl
71
	sudo apt install pdftk libxrender1 file pdf2svg       # for file upload, PDF and 'HTML to PDF' (wkhtmltopdf), PDF split
72

73
.. _wkhtml:
74

75
76
wkhtmltopdf
^^^^^^^^^^^
77

78
79
`wkhtmltopdf <http://wkhtmltopdf.org/>`_ will be used by QFQ to offer 'website print' and 'HTML to PDF' conversion.
The program is not included in QFQ and has to be manually installed.
80

81
82
83
84
* The Ubuntu package `wkhtmltopdf` needs a running Xserver - this does not work on a headless webserver.

  * Best is to install the QT version from the named website above.
  * In case of trouble with wkhtmltopdf, also install 'libxrender1'.
85

86
In `config-qfq-ini`_ specify the:
87

88
89
90
91
92
93
94
95
* installed `wkhtmltopdf` binary:

  * `WKHTMLTOPDF = /.../wkhtmltopdf`

* the site base URL:

  * `BASE_URL_PRINT = http://example.com/`

96

97
98
**Important**: To access FE_GROUP protected pages or content, it's necessary to disable the `[FE][lockIP]` check! `wkhtml`
will access the Typo3 page locally (localhost) and that IP address is different from the client (=user) IP.
99
100

Configure via Typo3 Installtool `All configuration > $TYPO3_CONF_VARS['FE']`: ::
101
102
103

   [FE][lockIP] = 0

104
105
106
107
108
**Warning**: this disables an important anti-'session hijacking' protection. The security level of the whole installation
will be *lowered*! Again, this is only needed if `wkhtml` needs access to FE_GROUP protected pages & content. As an
alternative to lower the security level, create a separated page subtree which is only accessible (configured via
Typosript) from specific IPs **or** if a FE-User is logged in.

109
110
If there are problems with converting/downloading FE_GROUP protected pages, check `SHOW_DEBUG_INFO = download` to debug.

HTML to PDF conversion
''''''''''''''''''''''

`wkhtmltopdf` converts a website (local or remote) to a (multi)-page PDF file. It's mainly used in `download`_.

Print
'''''

Different browser prints the same page in different variations. To prevent this, QFQ implements a small PHP wrapper

120
`print.php` with uses `wkhtmltopdf` to convert HTML to PDF.

122
123
124
125
126
127
128
129
130
131
Provide a `print this page`-link (replace {current pageId})::

	<a href="typo3conf/ext/qfq/qfq/api/print.php?id={current pageId}">Print this page</a>

Any parameter specified after `print.php` will be delivered to `wkhtmltopdf` as part of the URL.

Typoscript code to implement a print link on every page::

	10 = TEXT
	10 {
132
		wrap = <a href="typo3conf/ext/qfq/qfq/api/print.php?id=|&type=2"><span class="glyphicon glyphicon-print" aria-hidden="true"></span> Printview</a>

	}

Setup
-----

* Install the extension via the Extensionmanager.

  * If you install the extension by manual download/upload and get an error message
    "can't activate extension": rename the downloaded zip file to `qfq.zip` or `qfq_<version>.zip` (e.g. version: 0.9.1).

  * If the Extensionmanager stops after importing: check your memory limit in php.ini.

* Enable the online local-documentation_.
* Copy/rename the file *<Documentroot>/typo3conf/ext/<ext_dir>/config.example.qfq.ini* to
  *<Documentroot>/typo3conf/config.qfq.ini* and configure the necessary values: `config.qfq.ini`_
  The configuration file is outside the extension directory to not loose it during updates.

* When the QFQ Extension is called the first time on the Typo3 Frontend, the file *<ext_dir>/qfq/sql/formEditor.sql* will
151
  played and fills the database with the *Form editor* records. This also happens automatically after each software update of QFQ.

It's also possible to setup custom variables in `config.qfq.ini`.

E.g. to setup a contact address and reuse the information inside your installation do:

 * `config.qfq.in`::

		ADMINISTRATIVE_CONTACT = john@doe.com
		ADMINISTRATIVE_ADDRESS = John Doe, Hollywood Blvd. 1, L.A.
		ADMINISTRATIVE_NAME = John Doe

 * Somewhere in a `Form` or in `Report`::

      {{ADMINISTRATIVE_CONTACT:Y}}, {{ADMINISTRATIVE_ADDRESS:Y}}, {{ADMINISTRATIVE_NAME}}

A specified SELECT statement in `config.qfq.ini`_ in variable `FILL_STORE_SYSTEM_BY_SQL_1` (or `FILL_STORE_SYSTEM_BY_SQL_2`,
or `FILL_STORE_SYSTEM_BY_SQL_3`) will be fired. The query should have 0 (nothing happens) or 1 row. All columns will be
**added** to the existing STORE_SYSTEM. Existing variables will be overwritten. Be careful not to overwrite system values.

This option is useful to make generic custom values, saved in the database, accessible to all QFQ Report and Forms.
Access such variables via `{{<varname>:Y}}`.

In case QFQ should stop working if a given query does not select exact one record (e.g. a missing period), define an
error message: ::

  FILL_STORE_SYSTEM_BY_SQL_1 = "SELECT name FROM Person WHERE name='Doe'"
  FILL_STORE_SYSTEM_BY_SQL_ERROR_MSG_1 = Too many or to few "Doe's" in our database

This is

* a usecase, implemented via `fillStoreSystemBySql`_,
509
* a way to access `Period.id` with respect to the current period (the period itself is custom defined).

After a full QFQ installation, three things are prepared:

* a table `Period` (extend / change it to your needs, fill them with your periods),
* one sample record in table `Period`,
Carsten  Rose's avatar

515
* in `config.qfq.ini`_ the default definition of `FILL_STORE_SYSTEM_BY_SQL_1` will set the variable `periodId` during QFQ load.

a variable 'periodId' will automatically computed and filled in STORE SYSTEM. Access it via `{{periodId:Y0}}`.
To get the name and current period: ::

  SELECT name, ' / ', start FROM Period WHERE id={{periodId:Y0}}

Typically, it's necessary to offer a 'previous' / 'next' link. In this example, the STORE SIP holds the new periodId: ::

  SELECT CONCAT('id={{pageId:T}}&periodId=', {{periodId:SY0}}-1, '|Next') AS _Page, ' ', name, ' ', CONCAT('id={{pageId:T}}&periodId=', {{periodId:SY0}}+1, '|Next') AS _Page FROM Period AS s WHERE s.id={{periodId:SY0}}

Take care for minimum and maximum indexes (do not render the links if out of range).

DB USER privileges
^^^^^^^^^^^^^^^^^^

The specified DB User needs privileges to the database of at least: SELECT / INSERT / UPDATE / DELETE / SHOW.

To apply automatically QFQ-'DB UPDATE' the following rights are mandatory too: CREATE / ALTER

To get access to the Typo3 installation, 'dbuser' should also have acces to the Typo3 Database with at least SELECT / INSERT / UPDATE / DELETE.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If it is necessary to use a GET variable which exceeds SECURITY_GET_MAX_LENGTH limit, name the variable with '_<num>' at
554
the end. E.g. `my_long_variable_130`. Such a variable has an allowed length of 130 chars. Access the variable as
555
556
557
usual with the variable name: `{{my_long_variable_130:C:...}}`.

If you get a 'Page forbidden / not found' there might be some Webserver restrictions. E.g. the Typo3 example of `.htaccess`
in the Typo3 installation folder will forbid access to any extension documentation (which is a good idea on a productive
567
568
server). For a development server instead, deactivate the forbid rule of 'documentation'. In `.htaccess` (snippet from
Typo3 7.6 _.htaccess): ::

582
SIPs
----

The following is a technical background information. Not needed to just use QFQ.

583
The SIPs (=Server Id Pairs) are uniq timestamps, created/registered on the fly for a specific browser session (=user). Every SIP is
584
585
586
587
588
589
590
591
592
593
594
595
596
597
registered on the server (= stored in a PHP Session) and contains one or more key/value pairs. The key/value pairs never leave
the server. The SIPs will be used:

* to protect values not to be spoofed by anyone,
* to protect values not to be altered by anyone,
* to grant access, e.g.:

  * load and save forms,
  * upload files,
  * download files,
  * PHP AJAX pages.

SIPs becomes invalid, as soon as the current browser session is destroyed. The client (= user) can't manipulate the content
of SIPs - it's only possible to reuse already registered SIPs by the user, who already owns the session.

602

Access privileges
-----------------

The Typo3 FE Groups can be used to implement access privileges. Such groups are assigned to
603

604
605
606
607
608
609
610
* Typo3 FE users,
* Typo3 pages,
* and/or Typo3 content records (e.g. QFQ records).

This will be used for general page structure privileges.

A `record base` privileges controlling (e.g. which user can edit
611
612
which person record) will be implicit configured, by the way that records are viewable / editable (or not) through
SQL in the specific QFQ tt-content statements.

Typo3 QFQ content element
-------------------------

Insert one or more QFQ content elements on a Typo3 page. 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.

Databases
---------

A Typo3 / QFQ Installation needs at least two databases. One for the Typo3 installation and one for QFQ.

QFQ itself can be separated in 'QFQ system' and 'QFQ data' databases, if necessary (than at least three databases are needed).
Furthermore a `Form` can operate on any additional database, specified per `Form`.parameter.dbIndex and configured via `config.qfq.ini`_.

* Option 'A' is the most simple and commonly used.
* Option 'B' separate the T3 and QFQ databases on two database hosts.
* Option 'C' is like 'B' but with a shared 'QFQ data'-database between three 'Typo3 / QFQ' instances.
* Further variants are possible.

+---+----------------+--------------+-------------------------------+------------------------------+----------------------------------+

+---+----------------+--------------+-------------------------------+------------------------------+----------------------------------+

In `config.qfq.ini`_ mutliple database credentials can be prepared. Mandatory is at least one credential setup like
`DB_1_USER`, `DB_1_SERVER`, `DB_1_PASSWORD`, `DB_1_NAME`. The number '1' indicates the `dbIndex`. Increment the number
to specify further database credential setups.

Often the `DB_1_xxx` is identically to the used Typo3 database credentials.

If not explicit specified, 'QFQ system' and 'QFQ database' will use the same database with the same credentials (setup 'A').

To define separate 'QFQ data' and 'QFQ system', in `config.qfq.ini`_ define  `DB_1_USER`, ... (e.g. 'QFQ data') and `DB_2_USER`,
... (e.g. 'QFQ system') and specify the assignment::

	DB_INDEX_DATA = 1
	DB_INDEX_QFQ = 2

To let a form operate (show, load and save) on a different database, use `Form.parameter.dbIndexData` (see `form-parameter`_).

Different QFQ versions, shared database
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When using different QFQ versions and a shared 'QFQ data'-database, there is some risk of conflicting
'QFQ system' tables. Best is to always use the same QFQ version on all instances.

* Zero or more stores might be specified to be searched for the given VarName.
* If no store is specified, the by default searched stores are: **FSRVD** (=FORM > SIP > RECORD > VARS > DEFAULT).

867
868
* If the VarName is not found and a default value is given, the default is returned.
* If no value is found, nothing is replaced - the string '{{<VarName>}}' remains.
869
* If anywhere along the line an empty string is found, this **is** a value: therefore, the search will stop.

* The number of variables inside an input field or a SQL statement is not limited.
* A resultset of a SQL statement will be imploded over all: concat all columns of a row, concat all rows - there is no glue string.

* Example::
897

898
  {{SELECT id, name FROM Person}}
Carsten  Rose's avatar
Carsten Rose committed
899
900
  {{SELECT id, name, IF({{feUser:T0}}=0,'Yes','No')  FROM Person WHERE id={{r:S}} }}
  {{SELECT id, city FROM Address AS adr WHERE adr.accId={{SELECT id FROM Account AS acc WHERE acc.name={{feUser:T0}} }} }}
901

902
* Special case for `SELECT` input fields and FormElement.type=action `sqlValidate`. To deliver a result array specify an '!' before the SELECT: ::
903

904
   {{!SELECT ...}}

Column variables
^^^^^^^^^^^^^^^^

Syntax:  *{{<level>.<column>}}*

914
Only used in report to access outer columns. See `access-column-values`_ and `syntax-of-report`_.
915

916
917
There might be name conflicts between VarName / SQL keywords and <line identifier>. QFQ checks first for '<level>',
than for 'SQL keywords' and than for 'VarNames' in stores.
918
919
920

All types might be nested with each other. There is no limit of nesting variables.

921
922
Very specific: Also, it's possible that the content of a variable is again (including curly braces) a variable - this
is sometimes used in text templates, where the template is retrieved from a record and
923
924
925
specific locations in the text will be (automatically by QFQ) replaced by values from other sources.

.. _`sanitize-class`:
926
927

Sanitize class
928
929
930
931
932
933
--------------

* If a value violates a parameter sanitize class, the value becomes an empty string.
* Per store there is a default if sanitizing applies and if yes, which class.

  * Store *C* (Client=Browser) and store *F* (Form) will be sanitized with 'digit'.
934

935
* All `predefined-variable-names`_ have a specific default sanitize class. For these variables, it's not necessary
936
  to specify a sanitize class.
937
* All other variables (Store: C, F) get by default the sanitize class defined in the corresponding form. If not defined,
938
939
  the default class is 'digit'.
* A default sanitize class can be overwritten by individual definition: *{{a:C:all}}*
940
941
942
* If there is a sanitized class specified, it applies to all given stores.

.. _`variable-escape`:

Escape
------

Variables used in SQL Statements might cause trouble by using: NUL (ASCII 0), \\n, \\r, \\, ', ", and Control-Z.

To protect the web application the following `escape` types are available:

	* 'm' - `real_escape_string() <http://php.net/manual/en/mysqli.real-escape-string.php>`_ (m = mysql)
	* 'l' - LDAP search filter values will be escaped: `ldap-escape() <http://php.net/manual/en/function.ldap-escape.php>`_ (LDAP_ESCAPE_FILTER).
	* 'L' - LDAP DN values will be escaped. `ldap-escape() <http://php.net/manual/en/function.ldap-escape.php>`_ (LDAP_ESCAPE_DN).
	* 's' - single ticks will be escaped. str_replace() of ' against \\'.
	* 'd' - double ticks will be escaped: str_replace() of " against \\".
985
986
	* 'c' - config - the escape type configured in `config.qfq.ini`_.
	* ''  - the escape type configured in `config.qfq.ini`_.
987
988
989
990
991
992
993
994
	* '-' - no escaping.

* The `escape` type is defined by the fourth parameter of the variable. E.g.: `{{name:FE:alnumx:m}}` (m = mysql).
* It's possible to combine different `escape` types, they will be processed in the order given. E.g. `{{name:FE:alnumx:Ls}}` (L, s).
* Escaping is typically necessary for SQL or LDAP queries.
* Be careful when escaping nested variables. Best is to escape **only** the most outer variable.
* In `config.qfq.ini`_ a global `ESCAPE_TYPE_DEFAULT` can be defined. The configured escape type applies to all substituted
  variables, who *do not* contain a *specific* escape type.
995
* Additionally a `defaultEscapeType` can be defined per `Form` (separate field in the *Form editor*). This overwrites the
996
997
998
  global definition of `config.qfq.ini`. By default, every `Form.defaultEscapeType` = 'c' (=config), which means the setting
  in `config.qfq.ini`_.
* To suppress a default escape type, define the `escape type` = '-' on the specific variable. E.g.: `{{name:FE:alnumx:-}}`.
