We will achieve this functionality through EventObserver.
Here, I have used the event which is called
“controller_action_catalog_product_save_entity_after”
Step 1: Create event.xml in /etc/adminhtml folder in your module.

<?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="controller_action_catalog_product_save_entity_after"> <observer name="magemonkeys_saveproductlogic" instance="Magemonkeys\Saveproductlogic\Observer\SaveProduct" /> </event> </config> |
Step 2: Create a SaveProduct.php Observer in Observer Folder.

<?php namespace Magemonkeys\Saveproductlogic\Observer; use Magento\Framework\Event\ObserverInterface; class SaveProduct implements ObserverInterface { protected $catalogData; protected $_resource; public function __construct( \Magento\Framework\App\ResourceConnection $resource ) { $this->_resource = $resource; } public function execute(\Magento\Framework\Event\Observer $observer) { $connection = $this->_resource->getConnection(); $table_name = $this->_resource->getTableName('product_oem'); $productController = $observer->getController(); $data = $productController->getRequest()->getPostValue(); $mainProduct = $observer->getProduct(); $productId = $mainProduct->getId(); /* You can use you logic here */ if(isset($data['product']['product_oem']) && $productId){ $connection->query('DELETE FROM ' . $table_name . ' WHERE product_id = ' . (int)$productId . ' '); $productOems = $data['product']['product_oem']; if(!is_array($productOems)){ $productOems = array(); $productOems[] = (int)$data['product']['product_oem']; } foreach ($productOems as $k => $v) { $connection->query('INSERT INTO ' . $table_name . ' VALUES ( ' . $v . ', ' . (int)$productId . ',0)'); } } } } ?> |
After creating the above module, please run the upgrade, compile and static:content:deploy command to implement this module.
