如何在 OctoberCMS 插件中创建我的事件并在控制器中触发它？

Question

我试图在论坛中对问题进行投票后触发事件，以通知问题作者有关新开发的信息。 CMS 文档对于监听事件非常清楚，但对于自己创建事件却不清楚。所以我以 laravel 的方式创建了事件，如下所示：

author/myplugin/classess/events/QuestionVotedEvent.php

<?php namespace Author\Myplugin\Classes\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class QuestionVotedEvent
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    /**
     * Create a new event instance.
     *
     * @return void
     */

    public $question;
    public $voter;
    public $vote;
    public $url;


    public function __construct($question,$voter,$vote,$url)
    {
        $this->question = $question;
        $this->voter = $voter;
        $this->vote = $vote;
        $this->url = $url;

    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new PrivateChannel('channel-name');
    }
}

然后在boot()方法里面myplugin

Event::listen('author.myplugin.QuestionVoteEvent', function($question,$vote,$voter) {

    $author = Question::where('id',$question)->first();
    if(!$author)
    {
        return false;
    }
    //Check if the is an upvote and award rps to the author of the question
    if($vote==1)
    {
        //Get rps type
        $rpsType = RPSType::where('code','UV')->first();
        $rps = new RPS;
        $rps->from_user_id = $voter;
        $rps->to_user_id = $author->user_id;
        $rps->rps_type_id = $rpsType->id;
        $rps->rps = $rpsType->points;
        $rps->url = $url;
        $rps->save();
        //Next send notfication to the user 
        //mailing logicgoes here...

    }




});

    }

在我的控制器中 Event::fire(new QuestionVotedEvent($question,$vote,$voter,$url));

侦听器未按预期将数据传递到数据库 table。问题是处理程序没有处理事件。我还在侦听器 $event->question 中尝试过将数据从事件容器传递到处理程序，但没有成功。

我的问题似乎出在听众身上。尝试收听我的活动时，我似乎听不懂。如何解决这个问题？这是正确的方法还是您会建议更好的方法，我将不胜感激。

我不确定你没有找到这部分，它很容易触发和监听事件。

实际上你不需要创建事件你只需要 listen for them 和 fire at some point [如果你没有任何复杂的工作流程就可以]

让我把你的代码转换成..那样

Create an event in-short listening for event
you need to write this code inside your plugin's Plugin.php file's boot method

use Event;  // add this to top if needed 

class Plugin extends PluginBase
{
    [...]

    public function boot()
    {
        Event::listen('author.myplugin.QuestionVoteEvent', function ( 
           $question,
           $vote,
           $voter,
           $url
        ) {
            // your code 
            // [$question, $vote, $voter, $url] all 4 variable will be available here.
        }
    }
}

Now inside controller fire it directly

use Event; // add this to top if needed 


// from action fire event
Event::fire('author.myplugin.QuestionVoteEvent', [$question, $vote, $voter, $url]);

// note: this all 4 variables [$question, $vote, $voter, $url] will be passed
// to that event listener function as arguments and you can receive data there
