.. _What-does-it-do:

FORMidable extension (extension key “ameos\_formidable”) 2.0.0 and
higher.

delete typo3cond/temp\_CACHED\*


.. _Usage:

Usage
^^^^^

In the XML configuration of your FORMidable form, provide the name of
the m:n table for all fields that use m:n relations:

::

   <control>
           <datahandler:DBMM>
                   <tablename>tx_seminars_seminars</tablename>
                   <keyname>uid</keyname>
                   <labelname>title</labelname>
                   <mmrelations>
                           <relation field="categories"
   mmtable="tx_seminars_seminars_categories_mm" />
                           <relation field="place" mmtable="tx_seminars_seminars_place_mm" />
                           <relation field="lodgings" mmtable="tx_seminars_seminars_lodgings_mm" />
                           <relation field="foods" mmtable="tx_seminars_seminars_foods_mm" />
                           <relation field="speakers" mmtable="tx_seminars_seminars_speakers_mm" />
                           <relation field="partners"
   mmtable="tx_seminars_seminars_speakers_mm_partners" />
                           <relation field="tutors"
   mmtable="tx_seminars_seminars_speakers_mm_tutors" />
                           <relation field="leaders"
   mmtable="tx_seminars_seminars_speakers_mm_leaders" />
                           <relation field="target_groups"
   mmtable="tx_seminars_seminars_target_groups_mm" />

This will also work if you configure your form using TS Setup instead
of XML.


.. _Known-limitations:

Known limitations
^^^^^^^^^^^^^^^^^

This extension currently does not support bidirectional m:n relations.

This extension does not work (and is not needed) with FORMidable
1.x.x. That version of FORMidable brings its own m:n data handler
(which uses exactly the same format, but uses a separate data handler
name).


.. _Want-to-help-Or-found-a-bug:

Want to help? Or found a bug?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This extension is hosted on `Forge <http://forge.typo3.org/>`_ . If
you have found a bug, want to help or anything else, please use Forge.
