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¶

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;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-extension/backend/after-backend-page-render'
)]
final class MyEventListener
{
    public function __invoke(AfterBackendPageRenderEvent $event): void
    {
        $content = $event->getContent() . ' I was here';
        $event->setContent($content);
    }
}

New in version 13.0: The PHP attribute \TYPO3\CMS\Core\Attribute\AsEventListener has been introduced to tag a PHP class as an event listener. Alternatively, or if you need to be compatible with older TYPO3 versions, you can also register an event listener via the Configuration/Services.yaml file. Switch to an older version of this page for an example or have a look at the section Implementing an event listener in your extension.
