AfterBackendPageRenderEvent

New in version 12.0: The PSR-14 event AfterBackendPageRenderEvent has been introduced which serves as a direct replacement for the removed hooks:

• $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/backend.php']['constructPostProcess']

• $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/backend.php']['renderPreProcess']

• $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/backend.php']['renderPostProcess']

The PSR-14 event \TYPO3\CMS\Backend\Controller\Event\AfterBackendPageRenderEvent gets triggered after the page in the backend is rendered and includes the rendered page body. Listeners may overwrite the page string if desired.

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/after-backend-page-render'

Read how to configure dependency injection in extensions.

The corresponding event listener class:

EXT:my_extension/Classes/Backend/EventListener/MyEventListener.php

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Backend\EventListener;

use TYPO3\CMS\Backend\Controller\Event\AfterBackendPageRenderEvent;

final class MyEventListener
{
    public function __invoke(AfterBackendPageRenderEvent $event): void
    {
        $content = $event->getContent() . ' I was here';
        $event->setContent($content);
    }
}
