AfterUserLoggedInEvent¶

New in version 12.3

The event replaces the deprecated hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauthgroup.php']['backendUserLogin'] .

New in version 13.0

The event is also dispatched, when a successful frontend user login is performed.

The purpose of the PSR-14 event \TYPO3\CMS\Core\Authentication\Event\AfterUserLoggedInEvent is to trigger any kind of action when a backend or frontend user has been successfully logged in.

The TYPO3 Core itself uses this event in the TYPO3 backend to send an email to a user, if the user has successfully logged in. See EXT:backend/Classes/Security/EmailLoginNotification.php (GitHub).

Example¶

EXT:my_extension/Authentication/EventListener/MyEventListener.php

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Authentication\EventListener;

use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Core\Authentication\BackendUserAuthentication;
use TYPO3\CMS\Core\Authentication\Event\AfterUserLoggedInEvent;

#[AsEventListener(
    identifier: 'my-extension/after-user-logged-in',
)]
final readonly class MyEventListener
{
    public function __invoke(AfterUserLoggedInEvent $event): void
    {
        if (
            $event->getUser() instanceof BackendUserAuthentication
            && $event->getUser()->isAdmin()
        ) {
            // Do something like: Clear all caches after login
        }
    }
}

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.
