ModifyPageLayoutContentEvent¶

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/backend/modify-page-module-content'

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\Controller\Event\ModifyPageLayoutContentEvent;

final class MyEventListener
{
    public function __invoke(ModifyPageLayoutContentEvent $event): void
    {
        // Get the current page ID
        $id = (int)($event->getRequest()->getQueryParams()['id'] ?? 0);

        $event->addHeaderContent('Additional header content');

        $event->setFooterContent('Overwrite footer content');
    }
}
