将数据传递给 Laravel 事件

Question

我刚刚开始阅读eventsLaravel 的内容，现在已经被困了几个小时了。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));

正如您所看到的，我正在将一个eloquent对象传递给该事件。

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');
        });
    }
}

这就是我陷入困境的地方，如何访问我customer传递给事件的属性并访问它的属性email, first_name等我还需要将其传递到我的电子邮件模板才能访问这些属性以个性化电子邮件。

我在这条线上遇到错误$referrer->email

field email not found in class

任何帮助表示赞赏

这就是我从中得到的dd($referrer)

我只想能够访问属性。

Answer 1

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

该barryvdh/laravel-ide-helper软件包可能有助于解决此问题。

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

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

    // ...
}
