我刚刚开始阅读有关 laravel 中的 events 的内容，现在已经停滞了几个小时。这可能非常简单，但我遗漏了一些东西。

我这样触发事件

// 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，我正在将一个 eloquent 对象传递给该事件。

我创建了事件；

<?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');
        });
    }
}

这就是我遇到的问题，我如何访问传递给事件的 customer 并访问它的属性，如 email、first_name 等 我还需要将其传递到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 $referrer->email 这一行收到错误消息

在类中找不到字段电子邮件

感谢任何帮助

这是我从dd($referrer)

我只想能够访问属性。

最佳答案

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，因此它报告它丢失。

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 也可能有所帮助。

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

    // ...
}
