A lightweight domain event pattern implementation for Doctrine2.

Installation

With composer :

$ composer require knplabs/rad-domain-event

If you are using Symfony you can update your app/AppKernel.php file:

public function registerBundles()
{
 $bundles = array(
 // bundles here ...
 new Knp\Rad\DomainEvent\Bundle\DomainEventBundle();
 );
}

Usage

Setup your entity

First, make sure your entity implements the Provider interface and uses the ProviderTrait.

use Knp\Rad\DomainEvent;

class MyEntity implements DomainEvent\Provider
{
 use DomainEvent\ProviderTrait;
}

Raise event

Trigger any event from your entity, through the raise method. It will be turned into a Knp\Rad\DomainEvent\Event object and dispatched once your entity has been flushed.

use Knp\Rad\DomainEvent;

class MyEntity implements DomainEvent\Provider
{
 // ...
 public function myFunction($arg) {
 // your function behavior
 $this->raise('myEventName', ['anyKey' => $anyValue]);
 }
}

Listen to this event

use Knp\Rad\DomainEvent\Event;

class MyListener
{
 public function onMyEventName(Event $event) {
 // your function behavior 
 }
}

Then, of course, register your listener.

app.event_listener.my_event_listener:
 class: App\EventListener\MyEventListener
 tags:
 - { name: kernel.event_listener, event: myEventName, method: 'onMyEventName' }
