Event Listeners

In opposite to Entity Listeners, Event listeners are services that listen for all entities in your application.

See https://www.doctrine-project.org/projects/doctrine-orm/en/latest/reference/events.html#implementing-event-listeners for more info on event listeners.

To register a service to act as an event listener you have to tag it with the doctrine.event_listener tag:

Starting with Doctrine bundle 2.8, you can use the AsDoctrineListener attribute to tag the service.

PHP

1 // src/App/EventListener/SearchIndexer.php
namespace App\EventListener;

use Doctrine\Bundle\DoctrineBundle\Attribute\AsDoctrineListener;
use Doctrine\ORM\Event\LifecycleEventArgs;

#[AsDoctrineListener('postPersist'/*, 500, 'default'*/)]
class SearchIndexer
{
    public function postPersist(LifecycleEventArgs $event): void
    {
        // ...
    }
}

YAML

    App\EventListener\SearchIndexer:
        tags:
            -
                name: 'doctrine.event_listener'
                # this is the only required option for the lifecycle listener tag
                event: 'postPersist'

                # listeners can define their priority in case multiple subscribers or listeners are associated
                # to the same event (default priority = 0; higher numbers = listener is run earlier)
                priority: 500

                # you can also restrict listeners to a specific Doctrine connection
                connection: 'default'
