ModifyInfoModuleContentEvent

New in version 12.0

This event has been introduced as a more powerful and flexible alternative to $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/web_info/class.tx_cms_webinfo.php']['drawFooterHook'] which has now been removed.

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

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

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Info\EventListener;

use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Info\Controller\Event\ModifyInfoModuleContentEvent;

#[AsEventListener(
    identifier: 'my-extension/content-to-info-module',
)]
final readonly 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>');
        }
    }
}

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.
