In Symfony, you can dispatch an event using the EventDispatcher component. The EventDispatcher component allows you to dispatch events and register listeners that will be executed when those events are dispatched.
To dispatch an event in Symfony, you can follow these steps:
1 2 3 4 5 6 |
use SymfonyContractsEventDispatcherEvent; class MyEvent extends Event { // ... } |
1
|
$event = new MyEvent(); |
1
|
$dispatcher = $this->get('event_dispatcher'); |
1
|
$dispatcher->dispatch($event); |
For example, to create a listener for the MyEvent
event, you can define a service that has a method with the following signature:
1 2 3 4 |
public function onMyEvent(MyEvent $event) { // ... } |
Then, you can register this listener with the event dispatcher by calling the addListener()
method:
1
|
$dispatcher->addListener('my_event', [$myService, 'onMyEvent']); |
Note that the first argument of addListener()
is the name of the event, which is a string that identifies the event. The second argument is a callable that represents the listener method. In this case, the callable is an array that contains the instance of the service and the name of the method to call.
