Eventor

Simplifies dispatching and handling events. No need to keep track of underscored event names.

The main idea is to give your event class a readable name. The method name for handling that event in your event listener must be prefixed with when.

Examples:

Event: UserHasRegistered
Method: whenUserHasRegistered

Event: EmailWasSent
Method: whenEmailWasSent

How to use the module

1. Create your event class and pass any data to it that will be required for handling the event.

<?php

namespace Drupalmy_moduleEvents;

use SymfonyComponentEventDispatcherEvent;

class UserHasRegistered extends Event {

  public $user;

  public function __construct($user) {
    $this->user = $user;
  }

}
?>

2. Create your event listener by extending the EventListener class provided by the module. The method name for handling the event must follow the pattern when{EventClassName}.

<?php

namespace Drupalmy_moduleEventSubscriber;

use DrupaleventorEventListener;
use Drupalmy_moduleEventsUserHasRegistered;

/**
 * Class AdminNotifier.
 */
class AdminNotifier extends EventListener {

  public function whenUserHasRegistered(UserHasRegistered $event) {
    $registeredUser = $event->user; 
    
    // Notify site admin.
  }

}
?>

3. Register your event listener as a service in my_module.services.yml.

services:
  my_module.admin_notifier:
    class: Drupalmy_moduleEventSubscriberAdminNotifier
    arguments: []
    tags:
      - { name: event_subscriber }

4. Dispatch your event.

<?php

$event = new UserHasRegistered($user);
Drupal::service('eventor.event_dispatcher')->dispatch($event);
?>
