New in version 12.0: This event was introduced to replace and improve the method getDataStructureIdentifierPostProcess() ot the hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['workspaces']['modifyDifferenceArray'].

This event can be used to control the flex form parsing in an object oriented approach.


class TYPO3\CMS\Core\Configuration\Event\AfterFlexFormDataStructureParsedEvent

Listeners to this event are able to modify or enhance a flex form data structure that corresponds to a given identifier, after it was parsed and before it is used by further components.

Note: Since this event is not stoppable, all registered listeners are called. Therefore, you might want to namespace your identifiers in a way, that there is little chance they overlap (e.g. prefix with extension name).

See the note on FlexFormTools regarding the schema of $dataStructure.

Return type

setDataStructure(array $dataStructure)
