Magento 2 - Adding Template Block To Footer

by ADMIN 44 views

Introduction

When creating a custom theme for a Magento 2 store, it's often necessary to add custom functionality to the footer section. One common requirement is to include inline JavaScript code that needs to be executed after the page has loaded. In this article, we'll explore how to add a template block to the Magento 2 footer, allowing you to include custom JavaScript code and other content.

Understanding Magento 2 Theme Structure

Before we dive into the process of adding a template block to the footer, it's essential to understand the basic structure of a Magento 2 theme. A Magento 2 theme is composed of several directories and files, including:

  • app/design/frontend/ - This directory contains the theme files.
  • app/design/frontend/[Vendor]/[Theme]/ - This directory contains the theme-specific files.
  • Magento_Theme - This directory contains the Magento theme files.

Extending the Magento Blank Theme

In this example, we'll be extending the Magento blank theme. To do this, we need to create a new theme directory and copy the necessary files from the Magento blank theme.

mkdir -p app/design/frontend/[Vendor]/[Theme]
cp -r vendor/magento/theme-frontend-blank/* app/design/frontend/[Vendor]/[Theme]

Creating a Template Block

To add a template block to the footer, we need to create a new PHP file in the app/design/frontend/[Vendor]/[Theme]/Magento_Theme/layout directory. This file will contain the XML code that defines the template block.

touch app/design/frontend/[Vendor]/[Theme]/Magento_Theme/layout/footer_block.xml

footer_block.xml

In this file, we'll define the template block using the following XML code:

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="footer">
            <block class="Magento\Framework\View\Element\Template"
                   name="footer_block"
                   template="Magento_Theme::footer.phtml"
                   after="footer_links"/>
        </referenceBlock>
    </body>
</page>

In this code, we're referencing the footer block and adding a new block called footer_block after the footer_links block.

footer.phtml

Next, we need to create the footer.phtml file in the app/design/frontend/[Vendor]/[Theme]/Magento_Theme/templates directory. This file will contain the HTML code for the template block.

touch app/design/frontend/[Vendor]/[Theme]/Magento_Theme/templates/footer.phtml

footer.phtml

In this file, we'll add the following HTML code:

<?php
/**
 * Footer template block
 *
 * @var \Magento\Framework\View\Element\Template $this
 */
?>
<div class="footer-block">
    <!-- Add custom JavaScript code here -->
    <script>
        // Add custom JavaScript code here
    </script>
</div>

this code, we're adding a div element with a class of footer-block and a script tag that will contain the custom JavaScript code.

Adding Custom JavaScript Code

To add custom JavaScript code to the footer, we can use the footer_block block's getJsLayout method to add a new script tag.

<?php
/**
 * Footer template block
 *
 * @var \Magento\Framework\View\Element\Template $this
 */
?>
<div class="footer-block">
    <?php
    $this->getJsLayout()->addScript('footer_block_script', 'footer_block_script.js');
    ?>
    <script>
        // Add custom JavaScript code here
    </script>
</div>

In this code, we're adding a new script tag with the name footer_block_script and the file footer_block_script.js.

footer_block_script.js

Finally, we need to create the footer_block_script.js file in the app/design/frontend/[Vendor]/[Theme]/web/js directory. This file will contain the custom JavaScript code.

touch app/design/frontend/[Vendor]/[Theme]/web/js/footer_block_script.js

footer_block_script.js

In this file, we'll add the following JavaScript code:

// Add custom JavaScript code here
console.log('Footer block script loaded');

In this code, we're logging a message to the console to verify that the script has loaded.

Conclusion

In this article, we've explored how to add a template block to the Magento 2 footer. We've created a new theme directory, copied the necessary files from the Magento blank theme, and added a new template block to the footer. We've also added custom JavaScript code to the footer block and verified that it has loaded.

By following these steps, you can add custom template blocks to the Magento 2 footer and include custom JavaScript code to enhance the functionality of your theme.

Best Practices

When adding custom template blocks to the Magento 2 footer, it's essential to follow best practices to ensure that your code is maintainable and scalable.

  • Use a consistent naming convention for your template blocks and JavaScript files.
  • Keep your template blocks and JavaScript files organized and separate from the core Magento code.
  • Use the getJsLayout method to add custom JavaScript code to the footer block.
  • Verify that your custom JavaScript code is loaded correctly by logging messages to the console.
