Adding lines conditionally in Laravel's Mail notifications
When working with Mail notifications in Laravel, you’ll often be in a situation where you would want to render something based on some condition.
For instance, you may want to render a line in the Mail notification only when a certain attribute is present/true. How would you do that?
Well, there’s a handy method called when() in the Illuminate\Notifications\Messages\MailMessage class which can be used to do just that.
To use the when() method, all you’ll need is to pass the condition or a boolean value as its first parameter and a Closure that will return the line that you would want to render if the condition is met.
Here’s how you can use it.
<?php
namespace App\Notifications;
use Illuminate\Notifications\Notification;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Bus\Queueable;
class WelcomeNotification extends Notification implements ShouldQueue
{
use Queueable, SerializesModels;
public $user;
public function __construct($user)
{
$this->user = $user;
}
public function via($notifiable)
{
return ['mail'];
}
public function toMail($notifiable)
{
return (new MailMessage)
->greeting('Bonjour '.$this->user->name)
->when($this->user->isAdmin, function (MailMessage $mail) {
return $mail->line('You have got all the power!');
)
->line('Welcome to our platform.')
->line('Thanks')
}
}
The when() method works the similar way how you would set attributes in Laravel’s resource responses.
