Using Events and Listeners in Laravel 7 with Example
Laravel provides an excellent way to hook into a certain event in your application using Events and Listeners. This feature will allow you to subscribe and listen to various activities that took place in your application.
In simple words, think of event as something that has occurred in your application and listeners as a set of logic to respond with. Therefore, this allows us, developers, to make announcements within the application that something has happened and perform a set of operations based on that specific event.
As a result, Events and Listeners will further help to simplify our codes and refactor complicated tasks.
In this article, we’ll create Events and Listeners using an example of a post. Once a post is created, the users will be notified about the post through emails.
Creating Events and Listeners
First, we’ll start by creating an event PostCreated and a listener NotifyPostCreated. You can use the following artisan command to create one.
php artisan make:event PostCreated
php artisan make:listener NotifyPostCreated --event="PostCreated"
The command above will create events and listeners inside directories the ‘app/Events’ and ‘app/Listeners‘ folders respectively.
After that, you need to register your events and listeners in app/Providers/EventServiceProvider.php file.
The protected $listen property contains an array of all events and their listeners as key-value pairs. Next, we add the event PostCreated and the listener NotifyPostCreated to array $listen as shown below.
use App/Events/PostCreated;
use App/Listeners/NotifyPostCreated;
//...
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
//...
PostCreated::class => [
NotifyPostCreated::class,
],
];
Now that we have setup events and listeners, all that remains is to define some logic inside the event and listener. Then, finally dispatching/raising the event so execute a list of operations contained in each listener.

Laravel real time event broadcasting with socket.io example
In the today’s technogy age real time data has become an essential thing. So here, in this article i will share laravel real time event broadcasting with socket.io. Here in this example we will see how can we broadcast real times events.
Basically, to acheive this thing in our laravel application, we will use predis which is a laravel package, queue, socket.io, laravel-echo-server and event broadcasting.
So, we will need to install the above things which are not provided in the laravel appication by default. I will provide all the step to implement real time broadcasting event in the various steps from a fresh installation of laravel application. If you have already installed laravel application then you can directly jump on the next step. So without wasting our time let’s start the implementation process and follow all the steps as given below.
Step 1: Install Laravel
For installing fresh laravel application, you will just needto run the following command in your terminal or command prompt.
composer create-project --prefer-dist laravel/laravel realtimeapp
I have given a name realtimeapp to this application, you are frre to give the name of your choice.
Now, run the following command to give permission to the storage and cache directories.
sudo chmod -R 777 /var/www/html/realtimeapp/storage
sudo chmod -R 777 /var/www/html/realtimeapp/bootstrap/cache<br><br>
Step 2: Install predis
In this second step, we will need to install predis. So open your terminal and run the following command.
composer require predis/predis
composer require predis/predis
Step 3: Create event for broadcasting
Now we will need to create an event for broadcasting and in the event file we will set channal and write message. So run the following command to create event.
php artisan make:event SendMessage
Above command will create an event file SendMessage.php file under app/Events directory. So open this file and update it like below.
app/Events/SendMessage.php
<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Contracts\Broadcasting\ShouldBroadcastNow;
class SendMessage implements ShouldBroadcastNow
{
use InteractsWithSockets, SerializesModels;
public $data = ['asas'];
/**
* Create a new event instance.
*
* @return void
*/
public function __construct()
{
}
/**
* Get the channels the event should broadcast on.
*
* @return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new Channel('user-channel');
}
/**
* The event's broadcast name.
*
* @return string
*/
public function broadcastAs()
{
return 'UserEvent';
}
/**
* The event's broadcast name.
*
* @return string
*/
public function broadcastWith()
{
return ['title'=>'Notification message will go here'];
}
}

Php how to delete multiple rows through checkbox using ajax in laravel
First thing, we will need a table and i am creating products table for this example. So run the following query to create table.
CREATE TABLE `products` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
`description` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
`updated_at` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
Next, we will need to insert some dummy records in this table that will be deleted.
INSERT INTO `products` (`name`, `description`) VALUES
('Test product 1', 'Product description example1'),
('Test product 2', 'Product description example2'),
('Test product 3', 'Product description example3'),
('Test product 4', 'Product description example4'),
('Test product 5', 'Product description example5');
Now we are redy to create a model corresponding to this products table. Here we will create Product model. So let’s create a model file Product.php file under app directory and put the code below.
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{
protected $fillable = [
'name','description'
];
}
Step 2: Create Route
Now, in this second step we will create some routes to handle the request for this example. So opeen routes/web.php file and copy the routes as given below.
routes/web.php
Route::get('product', 'ProductController@index');
Route::delete('product/{id}', ['as'=>'product.destroy','uses'=>'ProductController@destroy']);
Route::delete('delete-multiple-product', ['as'=>'product.multiple-delete','uses'=>'ProductController@deleteMultiple']);
