AfterPageTreeItemsPreparedEvent

New in version 12.0: This PSR-14 event replaces the following hooks:

• $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['TYPO3\CMS\Workspaces\Service\WorkspaceService']['hasPageRecordVersions']

• $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['TYPO3\CMS\Workspaces\Service\WorkspaceService']['fetchPagesWithVersionsInTable']

The PSR-14 event \TYPO3\CMS\Backend\Controller\Event\AfterPageTreeItemsPreparedEvent allows prepared page tree items to be modified.

It is dispatched in the \TYPO3\CMS\Backend\Controller\Page\TreeController class after the page tree items have been resolved and prepared. The event provides the current PSR-7 request object as well as the page tree items. All items contain the corresponding page record in the special _page key.

Example

Registration of the event listener in the extension's Services.yaml:

EXT:my_extension/Configuration/Services.yaml

services:
  # Place here the default dependency injection configuration

  MyVendor\MyExtension\Backend\EventListener\MyEventListener:
    tags:
      - name: event.listener
        identifier: 'my-extension/backend/modify-page-tree-items'

Read how to configure dependency injection in extensions.

The corresponding event listener class:

<?php

final class MyEventListener
{
    public function __invoke(AfterPageTreeItemsPreparedEvent $event): void
    {
        $items = $event->getItems();
        foreach ($items as $item) {
            // Setting special item for page with id 123
            if ($item['_page']['uid'] === 123) {
                $item['icon'] = 'my-special-icon';
            }
        }
