将数据传递给 Laravel 事件

Question

我刚刚开始在 laravel 中阅读有关 events 的信息，现在已经卡了几个小时了。这可能很容易，但我错过了一些东西。

我像这样触发事件

// get the referrer
$referrer = Customer::where('promocode', $user->referral_code)->first();

// fire referral sign up event
Event::fire(new ReferralSignupEvent($referrer));

如您所见，我将 eloquent 对象传递给事件。

我创建事件；

<?php

namespace App\Events;

use App\Models\Customer;

class ReferralSignupEvent extends Event
{

    public $referrer;


    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct(Customer $referrer)
    {
        //
        $this->referrer = $referrer;
    }
}

我创建了监听器

<?php

namespace App\Listeners;

use App\Events\ReferralSignupEvent;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

class EmailReferralSignupConfirmation
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  ReferralSignupEvent  $event
     * @return void
     */
    public function handle(ReferralSignupEvent $event)
    {
        //
        $referrer = $event->referrer;

        $mailer = app()->make('mailer');

        $mailer->queue('emails.restaurant-welcome', ['referrer' => $referrer] , function ($message) use ($referrer) {
            $message->from('support@xxxx.com', 'xxx Restaurant Team');
            $message->subject('Welcome to xxx');
            $message->to($referrer->email)->bcc('support@xxx.com');
        });
    }
}

这是我卡住的地方，我如何访问我传递给事件的customer 并访问它的属性，如email, first_name 等 我还需要将其传递给我的电子邮件模板以访问这些属性以个性化电子邮件。

我在这一行遇到错误$referrer->email

field email not found in class

任何帮助表示赞赏

这是我从dd($referrer)得到的

我只是希望能够访问属性。

这不是代码错误。您的代码应该可以正常工作。这只是您的 IDE 的问题。由于字段属性在 Eloquent 模型上的工作方式，您的 IDE 不知道 email 字段确实存在，因此将其报告为缺失。

barryvdh/laravel-ide-helper 包可能有助于解决这个问题。

除了上述包之外，为您的 public $referrer; 属性提供适当的 PHPDoc 也可能会有所帮助。

class ReferralSignupEvent extends Event
{
    /**
     * The customer referrer.
     *
     * @var \App\Models\Customer
     */
    public $referrer;

    // ...
}
