ModifyInfoModuleContentEvent

New in version 12.0

The PSR-14 event \TYPO3\CMS\Info\Controller\Event\ModifyInfoModuleContentEvent allows the content above and below the info module to be modified. The content added in the event is displayed in each submodule of Web > Info.

The event also provides the getCurrentModule() method, which returns the current requested submodule. It is therefore possible to limit the added content to a subset of the available submodules.

Next to getRequest() and the getModuleTemplate() methods this event also features getters and setters for the header and footer content.

Access control

The added content is by default always displayed. This event provides the hasAccess() method, returning whether the access checks in the module were passed by the user.

This way, event listeners can decide on their own, whether their content should always be shown, or only if a user also has access to the main module content.

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\Info\EventListener\MyEventListener:
    tags:
      - name: event.listener
        identifier: 'my-extension/content-to-info-module'

The corresponding event listener class:

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Info\EventListener;

use TYPO3\CMS\Info\Controller\Event\ModifyInfoModuleContentEvent;

final class MyEventListener
{
    public function __invoke(ModifyInfoModuleContentEvent $event): void
    {
        // Add header content for the "Localization overview" submodule,
        // if user has access to module content
        if (
            $event->hasAccess() &&
            $event->getCurrentModule()->getIdentifier() === 'web_info_translations'
        ) {
            $event->addHeaderContent('<h3>Additional header content</h3>');
        }
    }
