I'm trying to send broadcast notification to users when data changes. But every time I try to send a notification, I get this error:
array_key_exists(): The first argument should be either a string or an integer
.
Here is my notification:
class MyNotification extends Notification
{
use Queueable;
public $games;
public $title;
public $summary;
public $url;
public function __construct($games)
{
$this->games = $games;
$this->title = "Your games";
$this->summary = "Games for {$games[0]->team}";
$this->url = "/some/url";
}
public function via($notifiable)
{
return ['mail','broadcast','database'];
}
/**
* Get the mail representation of the notification.
*
* @param mixed $notifiable
* @return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
return (new MailMessage)
->subject($this->title)
->line($this->summary);
}
/**
* Get the voice representation of the notification.
*
* @param mixed $notifiable
* @return PushMessage
*/
public function toPush($notifiable)
{
// ...
}
public function toBroadcast($notifiable)
{
return new BroadcastMessage($this->toArray($notifiable));
}
/**
* Get the array representation of the notification.
*
* @param mixed $notifiable
* @return array
*/
public function toArray($notifiable)
{
return [
'icon' => 'fa fa-calendar',
'text' => $this->summary,
'title' => $this->title,
'url' => $this->url
];
}
}
When I remove 'broadcast' from the via
array, everything works fine. I don't know what I'm doing wrong! Can someone help please? Thanks!

EDIT 2
In my constructor of my notification, I have a model that uses a composite key. As soon as when I delete this line: $this->games = $games;
, and edit $this->summary
to some string - it works! $games
is a collection of the Model Game
.
But I don't know why this happens?!
toArray()
– Mike_NotGuiltyuse Queueable;
and see if that clears things up any. At the very least it should make the trace shorter. If you're copying this from an exception report on your browser, it should also show you parameters that were passed toarray_key_exists
which might help you figure out the problem. – miken32
