How to create an custom event and observer for that event at backend in Magento2. For example I want to create an event that whenever an admin deletes a customer profile a separate log file is generated. Please help me with the detailed solution and the directory structure.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • There is no option to delete the order in magento 2.....You can create event as order_cancel_after for cancel the order. – Ranganathan Jul 13 at 11:43

You can achieve this using plugin instead of events

Create di.xml in app/code/Vendor/Module/etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Customer\Model\ResourceModel\CustomerRepository">
        <plugin name="customer_delete_around" type="Vendor\Module\Plugin\aroundCustomerDelete" />

And create a plugin with below code in Vendor\Module\Plugin\aroundCustomerDelete.php


namespace Vendor\Module\Plugin;

class aroundCustomerDelete
    public function aroundDeleteById(
        \Magento\Customer\Model\ResourceModel\CustomerRepository $subject,
        \Closure $proceed,
    ) {
        // This will proceed delete action
        $result = $proceed($customerId);

        $writer = new \Zend\Log\Writer\Stream(BP . '/var/log/test.log');
        $logger = new \Zend\Log\Logger();
        $logger->info('Your text message');

        return $result;

Or you can create a custom log file using This link

Or use customer_delete_before this event to run your script in observer

  • I have already executed it using plugin I want to know if its possible using event and observer – Naiwrita09 Jul 13 at 11:56
  • I have updated my answer....if you need demo let me know – Ranganathan Jul 13 at 11:57
