How to register a theme in Magento 2

Register a theme in Magento 2

Creating a custom theme in Magento 2 involves a process of registering your theme. In this post we will describe how to do it. All the awesome theme customizations are up to you.

Creating a new theme is similar to creating an extension in Magento 2.

First of all, let’s create a registration.php :

<?php
/**
 * 
 * Location app/design/frontend/Atwix/custom/registration.php
 *
 * @author Atwix Team
 * @copyright Copyright (c) 2016 Atwix (https://www.atwix.com/)
 * @package Atwix_Customtheme
 */

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::THEME,
    'frontend/Atwix/custom',
    __DIR__
);

Next, we will need to add an app/design/frontend/Atwix/custom/composer.json :

{
  "name": "atwix/theme-frontend-custom",
  "description": "N/A",
  "require": {
    "php": "~5.6.5|7.0.2|7.0.4|~7.0.6",
    "magento/framework": "100.1.*"
  },
  "type": "magento2-theme",
  "version": "100.1.1",
  "license": [
    "OSL-3.0",
    "AFL-3.0"
  ],
  "autoload": {
    "files": [
      "registration.php"
    ]
  }
}

Instead of the module.xml we will need a theme.xml, which will define the theme name and the dependency from the other theme:

<?xml version="1.0"?>
<!--
/**
 * 
 * Location app/design/frontend/Atwix/custom/theme.xml
 *
 * @author Atwix Team
 * @copyright Copyright (c) 2016 Atwix (https://www.atwix.com/)
 * @package Atwix_Customtheme
 */

-->
<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
    <title>Atwix Custom</title>
    <parent>Magento/blank</parent>
</theme>

Don’t forget to flush cache running the corresponding command from Magento 2 installation root directory:

bin/magento cache:flush

That’s all! Now, we are able to see our theme in the “Content > Themes”.
