ZF2共享模块事件管理器 [英] ZF2 Shared Modules Event Manager

问题描述

在特定事件发生时，我需要在每个模块中实现事件触发。我还需要所有其他模块，当这个事件触发时必须做一些工作，请注意。

I need to implement in each of my modules an event trigger when something specific happens. I also need that all the other modules that must to do some work when that event is trigger, be aware of it.

我正在尝试创建一些常见的端点我可以发送我的触发器，并且所有模块都需要听，但是我有一些麻烦，找出如何实现。

I'm trying to create some common endpoint where I can send my triggers, and where all the modules need to be listening, but I'm having some trouble figuring out how can I achieve that.

任何想法？ / p>

Any ideas?

推荐答案

根据对Andrew的回答，只要您的控制器扩展了 AbstractActionController （它最有可能的）已经是EventManager知道了，所以你可以直接在控制器操作中触发任何您喜欢的事件，只需执行...

Based on the comments to @Andrew's answer, as long as your controller extends the AbstractActionController (which it most likely does) it's already EventManager aware, so you can just go ahead and trigger any event you like in a controller action simply by doing...

<?php
namespace Application/Controller;

// usual use statements omitted for brevity ..

class IndexController extends AbstractActionController
{
    public function indexAction()
    {
        // trigger MyEvent
        $this->getEventManager()->trigger('MyEvent', $this);
    }

}

要听一些其他模块的引导，执行以下

To listen to that event in the bootstrap of some other module, do the following

public function onBootstrap(EventInterface $e)
{
    $app = $e->getApplication();
    // get the shared events manager 
    $sem = $app->getEventManager()->getSharedManager();
    // listen to 'MyEvent' when triggered by the IndexController
    $sem->attach('Application\Controller\IndexController', 'MyEvent', function($e) {
        // do something...
    });
}
