Adding lines conditionally in Laravel's Mail notifications

Amit Merchant · February 23, 2021 ·

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.


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.')

The when() method works the similar way how you would set attributes in Laravel’s resource responses.
