Magento events list: How to use them in Magento 2

Magento events list and observers are one of many different solutions to extending the core functionality of a Magento 2 powered eCommerce store. Thanks to events or observers, you can run your custom codes in response to a specific Magento event or even with a custom event. In this tutorial, we’re going to look at how to use the Magento events list in Magento 2

 

What are Magento events?

Magento 2 events are applied to run custom code in response to any particular Magento 2 event or custom event. Magento enables you to generate your own events that can be dispatched in your code. When an event is dispatched, it can pass data to any observers configured to watch that event.

What are observers in Magento?

Observers are a certain type of Magento class that can influence general behavior, performance, or change business logic. Observers are executed whenever the event they are configured to watch is dispatched by the event manager. Besides, observers are applied for catching the action which was triggered before or after events. In observers, you can set the required features or logic that is to be executed in response.

Example of Using Events in Magento 2:

That’s It. That’s the Magento events list sheet! Now that we understand the events and observers’ terminologies, let’s put them into use!

How to use Events and Observers  in Magento 2

1. Create event.xml file

You can generate event.xml file for different areas:

• Global area: app/code/Mage/HelloWorld/etc/events.xml
• Frontend area: app/code/Mage/HelloWorld/etc/frontend/events.xml
• Admin area: app/code/Mage/HelloWorld/etc/adminhtml/events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="my_module_event_before">
        <observer name="myObserverName" instance="MyCompany\MyModule\Observer\MyObserver" />
    </event>
    <event name="my_module_event_after">
        <observer name="myObserverName" instance="MyCompany\MyModule\Observer\AnotherObserver" />
    </event>
</config>

2. Create Observer class

If you want to create an observer, you must place your class file under your <module-root>/Observer directory. Your observer class should implement Magento\Framework\Event\ObserverInterface and define its execute function.

You can see the below example for the basic observer class structure:

namespace MyCompany\MyModule\Observer;

use Magento\Framework\Event\ObserverInterface;

class MyObserver implements ObserverInterface
{
  public function __construct()
  {
    // Observer initialization code...
    // You can use dependency injection to get any class this observer may need.
  }

  public function execute(\Magento\Framework\Event\Observer $observer)
  {
    // Observer execution code...
  }
}

Subscribing to events

Observers in Magento can be configured to see certain events in the events.xml file.

The observer XML element comes with the following properties:

• name (required) – The name of the observer for the event definition.
• instance (required) – The fully qualified class name of the observer.
• disabled – Determines whether this observer is active or not. The default value is false.
• shared – Determines the lifestyle of the class. Default is true.

You can see the below example to assign observers to watch certain events:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="my_module_event_before">
        <observer name="myObserverName" instance="MyCompany\MyModule\Observer\MyObserver" />
    </event>
    <event name="my_module_event_after">
        <observer name="myObserverName" instance="MyCompany\MyModule\Observer\AnotherObserver" />
    </event>
</config>

Note that observer names must be unique per event definition. You cannot have two observers with the same name in the same event definition to prevent an override.

3. Dispatch event

Now if you want to dispatch a Magento 2 event list which enables another module to change the word displayed. You can see the following example to dispatch an event with and without an array of data.

Events can be dispatched by utilizing the Magento\Framework\Event\Manager class. This class can be achieved through dependency injection by defining the dependency in your constructor.

namespace MyCompany\MyModule;

use Magento\Framework\Event\ManagerInterface as EventManager;

class MyClass
{
  /**
   * @var EventManager
   */
  private $eventManager;

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

  public function something()
  {
    $eventData = null;
    // Code...
    $this->eventManager->dispatch('my_module_event_before');
    // More code that sets $eventData...
    $this->eventManager->dispatch('my_module_event_after', ['myEventData' => $eventData]);
  }
}
