Magento version: 2.0.0

I copied the Magento_Checkout file to my custom vendor directory and renamed it, but the block and layout are not working for me when i modified some files.

How to overwrite them?

need to change the di.xml?

i just copied it.


In the following explanation I use the {...} notation to indicate placeholders you have to substitute with your own values.

Assuming you have created your own {magedir}/app/code/{Vendor}/{Module} (or {magedir}/vendor/{Vendor}/{Module} if you use composer) - from now on let's call it {yourmoduledir} - containing the {yourmoduledir}/etc/module.xml activation file you have to:

1) Define a preference

Create {yourmoduledir}/etc/di.xml with following content:

<?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\Checkout\Controller\{TheActionClassYouWantToOverride}" type="{Vendor}\{Module}\Controller\{TheActionClassThatContainTheOverride}" />

2) Define your route

Create {yourmoduledir}/etc/frontend/routes.xml with following content:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="standard">
        <route id="{YourRouteId}" frontName="{YourRouteFrontName}">
            <module name="{Vendor}_{Module}" />

3) Create the Action class (a.k.a. Controller) that contains the override

Create {yourmoduledir}/Controller/{TheActionClassThatContainTheOverride}.php

namespace {Vendor}\{Module}\Controller;

class {TheActionClassThatContainTheOverride} extends \Magento\Checkout\Controller\{TheActionClassYouWantToOverride}
    public function execute()
        // your code here

4) Update environment

Once all the above configuration and classes file are created, run the following commands from {magedir}:

# Enable module
bin/magento module:enable {Vendor}_{Module}

# Update config
bin/magento setup:upgrade

# In Production mode you need to generate plugin classes
bin/magento setup:di:compile

# Flush cache
bin/magento cache:flush

Hope it helps.
