Laravel Send Email When New User Registers

In this tutorial we're going to learn how we can send an email to the application admin user when a new user registers to your Laravel application.

In this example we're going to use events and listeners to know when a user has registered and the listener will then send an email to the admin of the application.

Register Controller

To create this boilerplate you simply use the following command.

php artisan make:auth

You will now have a new folder in your App/Http/Controllers folder called Auth. This will have controllers for logging in, register, forgotten password and resetting your password.

The register controller uses a trait of RegistersUsers.php this will give you the boilerplate methods for signing up new users.

As you can see from \Illuminate\Foundation\Auth\RegistersUsers::register it will dispatch a new Registered event, which we can listen for in our app.

Event Service Provider

Add the following to your application event provider.

<?php

namespace App\Providers;

use App\Listeners\NewUser;
use Illuminate\Support\Facades\Event;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
use Illuminate\Auth\Events\Registered;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        Registered::class => [
            SendEmailVerificationNotification::class,
            NewUser::class
        ],
    ];

    /**
     * Register any events for your application.
     *
     * @return void
     */
    public function boot()
    {
        parent::boot();

        //
    }
}

To generate new events you can add this to the $listen property. You list out an array using the event class as the key of the array and listeners are the node vales of the array. This means that a single event can perform multiple actions by adding more listeners to the event array.

New User Listener

The listener will need to take the user from the event class and send an email to the global mail.from.address. In the config folder you have a default mail.php file this has all the default settings for the email of your app. One of these settings is the global from and name email address for your application. As this is normally the admin user so we will be using this global email address in this example.

<?php

namespace App\Listeners;

use Illuminate\Auth\Events\Registered;
use App\Mail\AdminNewUser;
use Illuminate\Support\Facades\Mail;

class AdminNewUserListener
{
    /**
     * Handle the event.
     *
     * @param  Registered  $event
     * @return void
     */
    public function handle(Registered $event)
    {
        Mail::to(config('mail.from.address'))->send(new AdminNewUser($event->user));
    }
}

New User Mailable

The mailable class uses the markdown component functionality of Laravel and pass in the new user into the blade component. We can then post this information to the admin user so they know who has just signed up to the application.

<?php

namespace App\Mail;

use App\Models\User;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class AdminNewUser extends Mailable
{
    use Queueable, SerializesModels;

    /**
     * @var User
     */
    private $user;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct(User $user)
    {
        $this->user = $user;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->subject('New User')
            ->markdown('mail.new-user', [
                'user' => $this->user
            ]);
    }
}

New User Email Markdown

@component('mail::message')
# New User

A new user with email {{ $user->email }} has registered to your site.
@endcomponent

That's it, that's all the code you need to send the admin an alert when a new user registers to your application.
