Form
----

106
* Forms will be created by using the *Form editor* (HTML form). The Formeditor itself consist of two regular QFQ forms: *form* and *formElement*
107
108
109
110
* Every form consist of a) a *Form* record and b) multiple *FormElement* records.
* A form is assigned to a  *table*. Such a table is called the *primary table* for this form.
* There are three types of forms:

111
  * *Simple* form: the form acts on one record, stored in one table.
112

113
    * The form will create necessary SQL commands for insert, update and delete automatically.
114

115
  * *Advanced* form: the form acts on one record, stored in more than one table.
116

117
    * Fields of the primary table acts like a *simple* form, all other fields have to be specified with *addNupdate* records.
118

119
  * *Multi* form: the form acts simultanously on more than one record. All records use the same *FormElements*.
120

121
122
    * The *FormElements* are defined as a regular *simple* / or *advanced* form, plus a SQL Query, which selects and
      iterates over all records. Those records will be loaded at the same time.

* ''constants'' (=strings), this is the standard use case.
* ''variables'' retrieved from the stores (see below),
* ''SQL statements'' (limited set of),
* or any combination of the above.

136
* A variable (or SQL) statement is surrounded by curly braces:

155

157
* There are several stores, from where to retrieve the value. If a value is not found in one store, the next store is searched,
  until a value is found or there are no more stores available.
*   sdkf
158
* If anywhere along the line an empty string is found, this **is** a value: therefore, the search will stop.

* If no value is found, the value is an <empty string>.

URL Parameter
-------------

164
* URL (=GET) Parameter can be used in *forms* and *reports* as variables.
165
* If a value violates a parameter sanitize class, an exception is thrown.

170
171
172
173
174
175
* All values in Store *C* (Client) and store *F* (Form) will be sanitized:
* All :ref:`predefined-variable-names` have a specific default sanitize class. For these variables, it's not necessary
  to specify a sanitize class.
* All other variables (Store: C, F) get by default the sanitize class defined in the corresponding form. If not defined
  the default class is 'digit'.
* A default sanitize class can be overwritten by individual definition: *{{a:C:all}}*

  * **email**: [a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}
  * **min|max**: only usable in forms. Compares the value against an lower and upper limit (numeric or string).
  * **min|max date**:  only usable in forms. Compares the value against an lower and upper date or datetime.
  * **pattern**:  only usable in forms. Compares the value against a regexp.

* Hint: Preferable, parameter should be submitted by SIP, not by Client (=URL).

227
228
229
  * Warning: Data submitted via 'Client' can be easily spoofed and altered.
  * Best: Data submitted via SIP never leaves the server, cannot be spoofed or altered by the user.
  * SIPs can _only_ be defined by using *Report*. Inside of *Report* use columns 'Link' (with attribute 's'), 'page?' or 'Page?'.

SQL

325
* The detection of an SQL command is case *insensitive*.
326
* Leading  whitespace will be skipped.
327
* The following commands are interpreted as SQL commands:

331
332
333
  * SELECT
  * INSERT
  * UPDATE
  * DELETE
  * SHOW
Carsten  Rose's avatar

334

335
* A SQL Statement might contain parameters, including additional SQL statements. Inner SQL queries will be executed first.
Carsten  Rose's avatar
Carsten Rose committed
336
* All variables will be substituted one by one from inner to outer.
337
* Maximum recursion depth: 5 (a recursion depth of 2 is sometimes used for mailing with templates, 3 and more probably confuses too much and is therefore not practicable, but supported until depth of 5)
Carsten  Rose's avatar
Carsten Rose committed
338
* The number of variables inside an input field or a SQL statement is not limited.
339
* 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.
Carsten  Rose's avatar
Carsten Rose committed
340

341
* Example::
Carsten  Rose's avatar
Carsten Rose committed
342

343
  {{SELECT id, name FROM Person}}
344
345
  {{SELECT id, name, IF({{feUser}}=0,'Yes','No')  FROM Vorlesung WHERE sem_id={{keySemId:Y}} }}
  {{SELECT id, city FROM Address AS adr WHERE adr.p_id={{SELECT id FROM Account AS acc WHERE acc.name={{feUser}} }} }}
346
347
348
349
350

* Special case for SELECT input fields. To deliver a result array specify an '!' before the SELECT:

  *{{!SELECT ...}}*

351
  * This is only possible for the outermost SELECT.

'subrecord' present a list of records (called secondary records), typically to edit, delete or add such records. The list
   is defined as a SQL query. The number of records shown is not limited. These formelement will be rendered inside the
794
795
   form as a HTML table. The list is ordered by 1) formelement.class (action, container, native), 2) formelement.container,
   3) formelement.ord

   # Notice the **exclamation mark** after '{{' - this is necessary to return an array of elements, instead of a single string.

    * Example: *detail=id:personId,&12:xId,&{{a}}:personId*
    * By default, the given value will overwrite values on the target record. In most situations, this is the wished behaviour.
    * Exceptions of the default behaviour have to be defined on the target form in the corresponding formelement in the
      field *value*. E.g. `{{<columnname>:RS0}}` - For existing records, the store `R` will provide a value. For new
      records, store `R` is empty and store S will be searched for a value: the value defined in `detail` will be choosen. At
      last the store '0' is defined as a fallback.
    * *source table column name*: E.g. A person form is opened with person.id=5 (r=5). The definition `detail=id:personId` and `form=address`
      maps person.id to address.personId. On the target record, the column personId becomes '5'.
    * *Constant '&'*: Indicate a 'constant' value. E.g. `&12:xId` or `{{...}}` (all possibilities, incl. further SELECT
      statements) might be used.

An upload element is based on a file browse button and a delete button. Only one of them is shown at a time.
If there is no file already uploaded, the file browse button is displayed.

The user can than select a file from the local filesystem.
After choosing the file, the upload starts immediately, shown by a turning wheel. When the server received the whole file
and accepts the file, the browse button dissappears and the filename is shown, followed by a delete button.
Now, the user can delete the uploaded file (and maybe upload another one) or leave it as it is.
Until this point, the file is cached on the server but not copied to the final destination. The user have to save the
current record either to finalize the upload or to delete a previous uploaded file.

* FormElement. *parameter*:

  * *pathFileName*: Destination where to copy the file. A good practice is to specify a relative pathFileName - such an
    installation (filesystem and database) are moveable. If the final pathFileName should contain the original filename,
    the variable *{{_filename}}* can be used. Example::

      pathFileName={{SELECT 'fileadmin/user/pictures/', p.name, '-{{_filename}}' FROM Person AS p WHERE p.id={{r}} }}

Dynamic Update
--------------

Depending of the form requirements, it's necessary to update FormElements depending on the recent user input. E.g. a user
activates a checkbox and therefore the content of a select list should change.

Make a form dynamic:

* Mark all FormElements with {dynamic update}=enabled, which should send **or** receive a 'do update' signal.
* Define the receiving FormElements in a way, that they will interpret the recent user change. In the example, the FormElement
  'carPriceRange' is the sender and the receiving FormElement might be of type 'radio' or 'selectList'.

  [receiving formElement].parameter: itemList={{ SELECT IF({{carPriceRange}}='expensive','Ferrari,Tesla,Jaguar','General Motors,Honda,Seat,Fiat') }}

Syntax
------

    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 always select 3 rows, than the total number of rows are 5 x 3 = 15 rows.

1034
    There is a set of **variables** that will get replaced before the SQL-Query gets executed:

        See :ref:`variables` for a full list of all available variables.
1049

1050
1051
    Be aware that line.count / line.total have to be known before the query is fired. E.g. `10.sql = SELECT {{10.line.count}}, ... WHERE {{10.line.count}} = ...`
    won't work as expected. `{{10.line.count}}` can't be replaced before the query is fired, but will be replaced during processing the result!

1062
1063
        On a per column base, printing of columns can be suppressed. This might be useful to select values which will be

Structure
---------

1084
1085
1086
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.

Wrapping rows and columns: Level keys
-------------------------------------

1212
1213
Order and nesting of queries, will be defined with a typoscript-like 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.
1214
All `QFQ Keywords (Bodytext)`_.
