如何在 symfony2 中创建自定义事件 [英] How to create custom event in symfony2

问题描述

我想创建名为 user_logged 的自定义事件，以便我可以将我的侦听器附加到这些事件.

I want to create custom events called user_logged so that i can attach my listeners to those events.

我想在用户登录时执行一些功能.

I want to execute few functions whenever user has logged in.

推荐答案

创建一个扩展 SymfonyComponentEventDispatcherEvent 的类.

Create a class which extends SymfonyComponentEventDispatcherEvent.

然后，使用事件调度器服务来调度事件:

Then, use the event dispatcher service to dispatch the event:

$eventDispatcher = $container->get('event_dispatcher');
$eventDispatcher->dispatch('custom.event.identifier', $event);

您可以像这样注册您的事件侦听器服务:

You can register your event listener service like so:

tags:
    - { name: kernel.event_listener, event: custom.event.identifier, method: onCustomEvent }
