Artikel am 26. Februar 2025 überarbeitet
TYPO3 12 oder neuer
Seit TYPO3 12 kann man ein Event nutzen um das FlexForm in TYPO3 komplett zu überschreiben oder auch nur einzelne Teile zu ergänzen.
Der zu nutzende EventListener muss in der Services.yaml registriert werden:
services:
In2code\In2template\EventListener\ModifyTtAddressFlexForm:
tags:
- name: event.listener
event: TYPO3\CMS\Core\Configuration\Event\AfterFlexFormDataStructureParsedEvent So können dann vorhandene Felder modifiziert (oder das FlexForm komplett überschrieben werden):
<?php
declare(strict_types=1);
namespace In2code\In2template\EventListener;
use TYPO3\CMS\Core\Configuration\Event\AfterFlexFormDataStructureParsedEvent;
use TYPO3\CMS\Core\Utility\ArrayUtility;
use TYPO3\CMS\Core\Utility\GeneralUtility;
final class ModifyTtAddressFlexForm
{
private string $flexFormFile = 'EXT:in2template/Configuration/FlexForm/Extend/TtAddress.xml';
public function __invoke(AfterFlexFormDataStructureParsedEvent $event): void
{
$dataStructure = $event->getDataStructure();
if ($this->isTtAddressPlugin($event->getIdentifier())) {
$configurationNew = file_get_contents(GeneralUtility::getFileAbsFileName($this->flexFormFile));
if ($configurationNew !== false) {
ArrayUtility::mergeRecursiveWithOverrule($dataStructure, GeneralUtility::xml2array($configurationNew));
}
}
$event->setDataStructure($dataStructure);
}
private function isTtAddressPlugin(array $identifier): bool
{
return $identifier['type'] === 'tca'
&& $identifier['tableName'] === 'tt_content'
&& $identifier['dataStructureKey'] === 'ttaddress_listview,list';
}
} Man könnte das Array entweder direkt im EventListener konfigurieren oder alternativ eine FlexForm-Datei angeben, die dann Teile des originalen FlexForm überschreiben (beispielhaft unter EXT:in2template/Configuration/FlexForm/Extend/TtAddress.xml):
