Hooks

This is used in case you need to influence on a process of wrapping with drop zone of some specific content elements

• Register your hook in ext_localconf.php

  <?php
  
  $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['frontend_editing']['FrontendEditingPanel']['dropzoneModifiers'][] = \Your\NameSpace\YourClass::class;
  

• Create hook class to control drop zone wrapping process

  <?php
  
  use Your\NameSpace;
  
  class YourClass implements \TYPO3\CMS\FrontendEditing\EditingPanel\FrontendEditingDropzoneModifier
  {
      /**
      * @param string $table
      * @param integer $editUid
      * @param array $dataArr
      * @param string $content
      * @return string $content
      */
      public function wrapWithDropzone(
        string $table,
        int $editUid,
        array $dataArr,
        string &$content
      ): bool {
          // TODO: Implement wrapWithDropzone() method.
          // return true if no need for further processing, otherwise false
      }
  }
