PageContentPreviewRenderingEvent¶
New in version 12.0
This event has been introduced which serves as a drop-in replacement for the removed
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem']
hook.
Use the PSR-14 event
\TYPO3\CMS\Backend\View\Event\PageContentPreviewRenderingEvent
to ship an alternative rendering for a specific content type or
to manipulate the record data of a content element.
Example¶
Registration of the event listener in the extension's Services.yaml
:
services:
# Place here the default dependency injection configuration
MyVendor\MyExtension\Backend\EventListener\MyEventListener:
tags:
- name: event.listener
identifier: 'my-extension/preview-rendering-example-ctype'
Read how to configure dependency injection in extensions.
The corresponding event listener class:
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Backend\EventListener;
use TYPO3\CMS\Backend\View\Event\PageContentPreviewRenderingEvent;
final class MyEventListener
{
public function __invoke(PageContentPreviewRenderingEvent $event): void
{
if ($event->getTable() !== 'tt_content') {
return;
}
if ($event->getRecord()['CType'] === 'example_ctype') {
$event->setPreviewContent('<div>...</div>');
}
}
}
