  • Ok, and where must i save the custom di.xml file? Commented May 8, 2017 at 17:45

You can override the php file in your own custom module. You can create your module and override the php file like this:


You also need to create di.xml file at the following location wherein you will set the preference for your Class in classname.php


di.xml example

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
  <preference for="Magento\ModuleName\Model\Classname" type="Vendor\ModuleName\Model\Classname" />

classname.php example

namespace Vendor\ModuleName\Model;

class Classname extends \Magento\ModuleName\Model\Classname
   //your code goes here.
