Magento 2 Create Event Observer– Observers are great ways to extend the default functionality in Magento. Using Observers we can easily implement the custom changes required related to different-different functionalities. Here in this tutorial we are going to explain how you can create Event Observers in Magento 2.

Magento 2 Create Event Observer Example

Creating observer event in Magento 2 is totally different than the Magento 1. We need to create events.xml configuration file to create events-

Step 1 – Create events.xml

Go to etc folder and create events.xml and define the event obsever simply as below-

Magento 2 Create Event Observer Example:

<?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="sales_order_place_after">
		<observer instance="Tutorialsplane\HelloWorld\Observer\Sales\OrderPlaceAfter" name="tutorialsplane_helloworld_observer_sales_orderplaceafter_sales_order_place_after"></observer>
	</event>
</config>

Step 2 – Create Obsever

Now go to Observer folder and create folder named as Sales. Inside this sales folder create OrderPlaceAfter.php and add the code as below-

Magento 2 sales order place after Event Example:

<?php namespace Tutorialsplane\HelloWorld\Observer\Sales;

class OrderPlaceAfter implements \Magento\Framework\Event\ObserverInterface
{

    /**
     * Execute observer
     *
     * @param \Magento\Framework\Event\Observer $observer
     * @return void
     */
    public function execute(
        \Magento\Framework\Event\Observer $observer
    ) {
        //Your observer code goes here
    }
}
</pre?>

Thus you can create any observer event in magento 2.
