我正在尝试使用laravel 5.6中的Notification类发送电子邮件,这是我的新手。
我试图传递用户和预订信息,但是每次获得以下信息:
未定义变量:用户
这是我的successEmail.php:
<?php
namespace BOOK_DONATION\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
class successEmail extends Notification
{
use Queueable;
public $user;
public $book;
/**
* Create a new notification instance.
*
* @return void
*/
public function __construct($user,$book)
{
//
$this->user=$user;
$this->book=$book;
}
/**
* Get the notification's delivery channels.
*
* @param mixed $notifiable
* @return array
*/
public function via($notifiable)
{
return ['mail'];
}
/**
* Get the mail representation of the notification.
*
* @param mixed $notifiable
* @return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
return (new MailMessage)
->greeting('Dear'.$user->name.'thak you for creating donation for '.$book->name);
}
/**
* Get the array representation of the notification.
*
* @param mixed $notifiable
* @return array
*/
public function toArray($notifiable)
{
return [
//
];
}
}
这是调用类successEmail的函数:
public function doBook(Request $request){
$validatedData = $request->validate([
'title' => 'string|required|max:255',
'Author'=> 'string|required|max:255',
'Cover_image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
'Book_description'=>'string|required|max:255',
]);
$path= $request->Cover_image->store('images');
$uid=Auth::user()->id;
$country=Auth::user()->country;
$city=Auth::user()->city;
$book=Book::create(['title'=>$request->input('title'),
'Author'=>$request->input('Author'),
'user_id'=>$uid,
'country'=>$country,
'city' =>$city,
'Book_description'=>$request->input('Book_description'),
'path'=>$path,
]);
$user = Auth::user();
$user->notify(new successEmail($user,$book));
return redirect('/donation/create')->with('status', 'Thank you for your donation');
}
如您所见,我将用户和book变量传递给了构造函数,并将它们声明为公共变量,那么我想念的是什么?

这些变量在函数范围中不存在,但它们确实作为类属性存在,因此应将其视为此类。
return (new MailMessage)
->greeting('Dear '.$this->user->name.' thank you for creating donation for '.$this->book->name);

您需要调用$ this-> user来访问类范围内的变量。
/**
* Get the mail representation of the notification.
*
* @param mixed $notifiable
* @return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
return (new MailMessage)
->greeting('Dear'.$this->user->name.'thak you for creating donation for '.$this->book->name);
}

您应该尝试以下操作:

那件事也发生在我身上。在toMail函数中,您需要重新声明像这样的变量
$ user = $ this-> user;
然后您像这样调用变量
->line('user:'.''.$user,'')
