How to solve laravel notification with broadcast ? Laravel 5.3 - php

Question

My controller is like this :
public function add($param)
{
...
$message = Message::create([
...
'created_at' => Carbon::now(),
'updated_at' => Carbon::now()
]);
Notification::send($notify_to, new MessageInsert($message));
dd($message);
return $message;
}
My MessageInsert is like this :
<?php
namespace App\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class MessageInsert extends Notification implements ShouldBroadcast, ShouldQueue
{
use Queueable;
private $data;
public function __construct($data)
{
$this->data = $data;
}
public function via($notifiable)
{
return ['broadcast','database','mail'];
}
public function toArray($notifiable)
{
return [
'id' => $this->data->id,
...
];
}
public function toMail($notifiable)
{
return (new MailMessage)
->greeting('Hello!')
->line('...')
->action('...')
->line('Thank you!');
}
}
If like this :
return ['broadcast','database','mail'];
The result of dd($message); is error
But if like this :
return ['database','mail'];
The result of dd($message); is array of $message
Why there is error when I use broadcast?

Answer 1

Did you try adding the toBroadcast function?
public function toBroadcast($notifiable) {
return new BroadcastMessage([ 'invoice_id' => $this->invoice->id, 'amount' => $this->invoice->amount, ]);
}
