Laravel | Passing variable in Notify - php

Question

I want to send a mail to Notify, it works but when I try to put the variables, It returns that they are undefined. I don't understand how to pass a variable to Notify, I tried to do ->withResult($result) but it didn't work out.
Here is the controller:
$result = Review::where('user_hash', '=', $data['lname_c'])->where('email', $data['email_c'])->orderBy('created_at', 'desc')->first();
$result->notify(new SendReview());
And my SendReview.php notifications:
public function toMail($notifiable)
{
return $result['invitation_id']; // test to check if variable is passed
return (new MailMessage)
->line('Test.')
->action('Nani', url($url))
->line('Thank you');
}
There is user_hash and invitation_id in my Review table, I want to pass them to the notify. When I do return $result['invitation_id']; it works. Hope I am understandable, I checked for duplicate questions and couldn't find one.

Answer 1

This is how they do it in docs.
$arr = [ 'foo' => "bar" ];
$result->notify(new SendReview($arr));
And in your SendReview.php
...
protected $arr;
public function __construct(array $arr) {
$this->arr = $arr;
}
public function toMail($notifiable) {
// Access your array in here
dd($this->arr);
}

Answer 2

You must use $notifiable variable in your Notification class.
It is an instance of the class to which the notification is being sent. So here your review object is passed as $notifiable variable.
You can try to log it as logger($notifiable) in toMail() method and check its properties.

For people interested in passing an object e.g $msg_recipient and sending an email to a specific user from a controller.
Controller:
Remember to add use Illuminate\Support\Facades\Notification;
Notification::route('mail',$msg_recipient->email)
->notify(new MsgReceived($msg_recipient));
In your notification __construct
public function __construct($msg_recipient)
{
$this->username = $msg_recipient->username;
}
toMail function
public function toMail($notifiable)
{
$username = $this->username;
return (new MailMessage)
->greeting('Hello, '.$username)
->line('You received a brand new msg!')
->action('View msg', url('/'.$username));
}
