取消通知Laravel 5.3（Via）

Question

So, let's say that I want to have my Notification Check logic within Via (as in, should this be sent based on a variable on the User). I notice that, if I do it this way in via:

return $notifiable->comment_email ? ['mail'] : false; 

it will successfully send if comment_email is true on the User. However, if it is false, then I want the notification to be cancelled all together, which I assumed returning False would do - it does not, just throws an error. So how would I cancel it in the via? Is it possible?

Answer 1

instead return false you must return an empty array:

return $notifiable->comment_email ? ['mail'] : [];
