# Events
# Introduction
Event Listeners in Bagisto are a way to implement the observer pattern, where listeners respond to events that occur in the application. Events can be thought of as announcements made by the application, and listeners are the actions taken in response to those announcements. All event classes in Bagisto are stored in the Providers folder, and the listeners are stored in the Listeners folder.
In Bagisto, events and listeners are organized in a clear and structured manner:
- Events are typically stored in the Events folder.
- Listeners are stored in the Listeners folder.
This organization makes it easy to manage and locate the event-driven components of your application.
To learn in detail about Controllers, you can visit the Laravel documentation here (opens new window).
# Creating an Event Class
# Using Package Generator
If you have the Bagisto Package Generator installed, you can use the following command to create a new event class in the packages/Webkul/Blog/src/Events directory:
php artisan package:make-event BlogEvent Webkul/Blog
If the event class already exists, you can use the --force option to overwrite it:
php artisan package:make-event BlogEvent Webkul/Blog --force
Alternatively, if you don't have the package generator, you can create the file manually by creating a new class in the packages/Webkul/Blog/src/Events directory.
# Manually Registering Events
In Bagisto, you register events manually in the boot method of your EventServiceProvider.php file. Here is an example of how to register events:
/**
* Register any other events for your application.
*
* @return void
*/
public function boot()
{
//...
Event::listen('event.name', 'path-upto-listener@function');
}
In this example, event.name is the name of the event, and path-upto-listener@function is the listener method that will handle the event.
# Manually Registering Listeners
When registering events, you specify the listener function to be executed when an event is triggered. Here is an example of how to register a listener:
class EventServiceProvider extends ServiceProvider
{
/**
* Bootstrap services.
*
* @return void
*/
public function boot()
{
//...
Event::listen('checkout.order.save.after', 'Webkul\Admin\Listeners\Order@sendNewOrderMail');
}
}
In this example, the checkout.order.save.after event will trigger the sendNewOrderMail method of the Order listener in the Webkul\Admin\Listeners namespace.
# Specifying Events
In Bagisto, events are typically fired before and after the execution of CRUD operations. This allows listeners to perform additional actions, such as logging, notifications, or data manipulation, at specific points in the lifecycle of an operation.
For example, you might have events fired during product creation, updating, or deletion. Here’s an example of firing events before and after saving an order:
namespace Webkul\Sales\Repositories;
use Webkul\Sales\Contracts\Order;
class OrderRepository extends Repository
{
public function create(array $data)
{
Event::dispatch('sales.order.create.before', $data);
$order = parent::create($data);
Event::dispatch('sales.order.create.after', $order);
return $order;
}
}
# Events Fired in Bagisto
In Bagisto, there are several events fired throughout its operations, allowing developers to hook into specific points in the application's lifecycle to customize behavior or add functionality. Here's a list of events that are fired in Bagisto, which you can listen to and handle as needed by creating event listeners:

# Events Listen in Bagisto
Event listen in bagisto is given below with their functionality.
Events name functionality bagisto.shop.layout.body.after Listing this event to load css of shop layout. bagisto.admin.layout.head Listing this event to load css of admin layout. checkout.order.save.after Listing this event to send notification of new order. sales.order.update-status.after Listing this event to send notification of when order status is changed. sales.invoice.save.after Listing this event to add paypal smart button. bagisto.shop.customers.login_form_controls.before Listing this event to add social login buttons. bagisto.shop.products.view.compare.after Listing this event to add social share buttons.
# Listening to Existing Events
Bagisto uses events and listeners to implement the observer pattern, allowing you to respond to various actions and events within the application. You can listen to specific events and execute custom code when those events are triggered.
# Registering a Listener
Open the EventServiceProvider.php file located in the Providers directory of your Bagisto application. This file is where you register event listeners.
Inside the boot() method of EventServiceProvider.php, use the Event::listen method to register your listener. This method takes the event name and a callback function or a class method that will handle the event.
Event::listen('checkout.order.save.after', 'Webkul\Notification\Listeners\Order@createOrder');
In the example above, we are listening to the checkout.order.save.after event and specifying the createOrder function from the Order listener class in the Webkul\Notification\Listeners namespace.
Replace 'checkout.order.save.after' with the specific event you want to listen to. In this example, it listens to the event triggered after saving an order during checkout.
By registering the listener, you have associated the createOrder function with the checkout.order.save.after event. Whenever this event is triggered, the specified function will be executed.
You can modify the listener function according to your requirements to perform the desired operation.
