Laravel 9 Event Example Tutorial

Hi Guys,

Today, I will learn you how to create event example in laravel 9. We will show a simple event example in laravel 9. Events provide a simple observer implementation, allowing you to subscribe and listen for events in your application. In these posts, you can learn how to create event for email send in your laravel 9 application. event is very helping to create proper programming way. First, create event using below command.

Step 1: Download Laravel

Let us begin the tutorial by installing a new laravel application. if you have already created the project, then skip following step.

composer create-project laravel/laravel example-app

Step 2: Add Event

php artisan make:event SendMail

Next, you can see file in this path

app/Events/SendMail.php

<?php

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;

class SendMail
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $userId;

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

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new PrivateChannel('channel-name');
    }
}

Step 3: Add Listener

Now, I need to create event listener for "SendMail" event. So create event listener using bellow command.

php artisan make:listener SendMailFired --event="SendMail"

In this event listener we have to handle event code, i mean code of mail sending, Before this file you have to check your mail configration, If you did not set then you can set this way :How to set gmail configration for mail in Laravel 8?.

app/Listeners/SendMailFired.php.

<?php

namespace App\Listeners;

use App\Events\SendMail;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use App\Models\User;
use Mail;

class SendMailFired
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  SendMail  $event
     * @return void
     */
    public function handle(SendMail $event)
    {
        $user = User::find($event->userId)->toArray();

        Mail::send('eventMail', $user, function($message) use ($user) {
            $message->to($user['email']);
            $message->subject('Event Testing');
        });
    }
}

Step 4: Add in Providers

Now we require to register event on EventServiceProvider.php file so, open app/Providers/EventServiceProvider.php and copy this code and put in your file.

<?php

namespace App\Providers;

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

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

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

Step 5: Add Route

Now In This Setp, we are create route.

<?php

use App\Http\Controllers\EventController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/event', [EventController::class, 'index'])->name('event.index');

Step 6: Add Controller

At Last we are ready to use event in our controller file. so use this way:

app/Http/Controllers/EventController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Event;
use App\Events\SendMail;

class EventController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        Event::dispatch(new SendMail(1));
        dd('hi');
    }
}
