This event is fired in the :php:`\TYPO3\CMS\Backend\Backend\ToolbarItems\ClearCacheToolbarItem` class and allows extensions to modify the clear cache actions, shown in the TYPO3 Backend top toolbar. The event can be used to change or remove existing clear cache actions, as well as to add new actions. Therefore the event also contains, next to the usual "getter" and "setter", the convenience method :php:`add` for the :php:`cacheActions` and :php:`cacheActionIdentifiers` arrays. Registration of the Event in your extensions' :file:`Services.yaml`: .. code-block:: yaml MyVendor\MyPackage\Toolbar\MyEventListener: tags: - name: event.listener identifier: 'my-package/toolbar/my-event-listener' The corresponding event listener class: .. code-block:: php use TYPO3\CMS\Backend\Backend\Event\ModifyClearCacheActionsEvent; class MyEventListener { public function __invoke(ModifyClearCacheActionsEvent $event): void { // do magic here } } Impact ====== This event can be used to modify the clear cache actions, shown in the TYPO3 Backend top toolbar. .. index:: PHP-API, ext:backend
