In this article, I will guide you on how to use a plugin to block Override in Magento 2.
Add di.xml file in app/code/Magemonkeys/HelloWorld/etc/ and copy the following code in it:
|
1 2 3 4 5 6 7 |
<?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\Catalog\Block\Product\View"> <plugin name="magemonkeys-helloworld-product-block" type="Magemonkeys\HelloWorld\Plugin\ProductPlugin" sortOrder="5" /> </type> </config> |
Here enable all the methods containing before, after, and around methods.
beforeGetProduct method will be active.aroundGetPrduct will be active.afterGetProduct method will be active. You can look into the var/log/debug.log and confirm the method execution sequence.Add ProductPlugin.php file in app/code/Magemonkeys/HelloWorld/Plugin/ and copy the following code in it:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 |
<?php namespace Magemonkeys\HelloWorld\Plugin; class ProductPlugin { public function beforeGetProduct(\Magento\Catalog\Block\Product\View $subject) { // logging to test override $logger = \Magento\Framework\App\ObjectManager::getInstance()->get('\Psr\Log\LoggerInterface'); $logger->debug(__METHOD__ . ' - ' . __LINE__); } public function afterGetProduct(\Magento\Catalog\Block\Product\View $subject, $result) { // logging to test override $logger = \Magento\Framework\App\ObjectManager::getInstance()->get('\Psr\Log\LoggerInterface'); $logger->debug(__METHOD__ . ' - ' . __LINE__); return $result; } public function aroundGetProduct(\Magento\Catalog\Block\Product\View $subject, \Closure $proceed) { // logging to test override $logger = \Magento\Framework\App\ObjectManager::getInstance()->get('\Psr\Log\LoggerInterface'); $logger->debug(__METHOD__ . ' - ' . __LINE__); // call the core observed function $returnValue = $proceed(); // logging to test override $logger->debug(__METHOD__ . ' - ' . __LINE__); return $returnValue; } } ?> |
