将数据传递给 Laravel 事件

Question

我刚开始在 laravel 中阅读有关 events 的内容，现在已经被困了几个小时。这可能很简单，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，我将 eloquent 对象传递给事件。

我创建了活动；

<?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。

我在这一行遇到错误 $referrer->email

field email not found in class

感谢任何帮助

这是我从dd($referrer)

那里得到的

我只想访问属性。

Answer 1

这不是代码错误。您的代码应该可以正常工作。这只是您 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 软件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;

    // ...
}
