FlexForm field¶
New in version 13.0
When using the flex type, TYPO3 takes care of
generating the according database field.
A developer does not need to define this field in an extension's
ext_tables.sql file.
Renders a FlexForm element. Essentially, this consists in a hierarchically organized set of fields which will have their values saved into a single field in the database, stored as XML.
The general idea is: There is a data structure that defines which and how single fields should be displayed, re-using all the TCA column type possibilities. The actual values of single fields are then stored in an XML representation within this "flex" field.
