**How to create custom event in Magento 2**

Magento 2, Using events and observers, you can run your custom code in response to a specific Magento event or even a custom event. Events are dispatched by modules when certain actions are triggered. In addition to its own events, Magento allows you to create 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.

- **Event:** events are generally dispatched from the Magento\\Framework\\Event\\Manager class. There are many core events already available to use, but you can also create custom events you want that can be dispatched in your actions’ code.
- **Observer:** the observer is basically a class that implements Magento\\Framework\\Event\\ObserverInterface interface. You can also set your own custom code or required functionality

You can define **events.xml** based on area. Below the type of location, you can define events.xml file.

- **Global : \[dt\_highlight color=”” text\_color=”” bg\_color=””\]etc/ folder\[/dt\_highlight\]** for admin and frontend.
- **Frontend : \[dt\_highlight color=”” text\_color=”” bg\_color=””\]etc/frontend\[/dt\_highlight\]** folder for frontend scope.
- **Back End(adminhtml) : \[dt\_highlight color=”” text\_color=”” bg\_color=””\]etc/adminhtml\[/dt\_highlight\]** folder for admin scope.
- **REST API : \[dt\_highlight color=”” text\_color=”” bg\_color=””\]etc/webapi\_rest\[/dt\_highlight\]** folder for REST API scope.
- **SOAP API : \[dt\_highlight color=”” text\_color=”” bg\_color=””\]etc/webapi\_soap\[/dt\_highlight\]** folder for SOAP API scope.

Introduce several ways to create custom event in Magento 2, Taken **Dolphin** as Package name and **CustomEvent** as Modulename for simplicity. code snippets are under a module named **Dolphin\_CustomEvent**.

Before creating the custom event, we need to create a new module We already have a blog on “[how to create a basic module in Magento 2](https://dolphinwebsolution.com/how-to-create-module-in-magento-2)“. We need to create **module.xml** and **registration.php** file. You can create **module.xml** and **registration.php** from this tutorial.

#### Step:1 Create Controller (Dispatching events)
Create a **“Index.php”** file in the **app/code/Dolphin/CustomEvent/Controller/Index** folder with the following code.

```
<?php

namespace Dolphin\CustomEvent\Controller\Index;

use Magento\Framework\DataObject;
use Magento\Framework\App\Action\Action;

class Index extends Action
{
    public function execute()
    {
        $blogData = new DataObject(['blog_id' => '1', 'blog_title' => 'Blog Title']);
        $this->_eventManager->dispatch('dolphin_custom_event_blog',
            [
                'blog' => $blogData
            ]
        );
        echo "Dolphin Custom Event";exit;
    }
}
```

- **\_eventManager->dispatch :** is To dispatch an event, call the dispatch function of the event manager class and provide it with the name of the event you want to dispatch along with an array of data you wish to provide to observers.
- **Event Name:** dolphin\_custom\_event\_blog

Read this: [Event Web API Rest and Web API Soap in Magento 2](https://dolphinwebsolution.com/how-to-use-event-only-in-web-api-rest-and-web-api-soap)

#### Step:2 Create Event File
Create an **“events.xml”** file in the **app/code/Dolphin/CustomEvent/etc** folder with the following code.

```
<?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="dolphin_custom_event_blog">
        <observer name="dolphin_blog_custom"
                  instance="Dolphin\CustomEvent\Observer\GetBlog"/>
    </event>
</config>
```

This event file for admin and frontend both areas.

A name attribute is a custom event.

An instance is a class name, we have to manage events.

#### Step:3 Create Observer Class
Create a **“GetBlog.php”** file in the **app/code/Dolphin/CustomEvent/Observer** folder with the following code.

```
?php

namespace Dolphin\CustomEvent\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class GetBlog implements ObserverInterface
{
    public function execute(Observer $observer)
    {
        $blogData = $observer->getEvent()->getBlog();
        $blogId = $blogData->getBlogId();
        $blogTitle = $blogData->getBlogTitle();

        $writer = new \Zend_Log_Writer_Stream(BP . '/var/log/blog.log'); //custom log file
        $logger = new \Zend_Log();
        $logger->addWriter($writer);
        $logger->info('blog id: '.$blogId);
        $logger->info('blog title: '.$blogTitle);

        return $this;
    }
}
```

you can fetch data in $observer argument.

Run Command \[dt\_highlight color=”” text\_color=”” bg\_color=””\]**php bin/magento c:c**\[/dt\_highlight\]

### Result:
Goto to the magento root/var/log you see outr [custom log file](https://magento.stackexchange.com/questions/75935/how-to-create-custom-log-file-in-magento-2) blog.log

\[dt\_code\]2021-10-05T12:04:30+00:00 INFO (6): blog id: 1
2021-10-05T12:04:30+00:00 INFO (6): blog title: Blog Title\[/dt\_code\]
