# How to Insert Code Under WooCommerce Single Product: A Beginner’s Guide
Adding custom code to your WooCommerce single product pages opens up a world of possibilities. You can enhance the customer experience, display crucial information, or even integrate with other services. This guide will walk you through the process, even if you’re completely Learn more about How To Use Shipping Classes In Woocommerce new to coding.
Understanding the Method: Action Hooks
WooCommerce relies heavily on action hooks. Think of these as strategically placed “hooks” in the code where you can hang your own custom functions. By using the right hook, you can insert your code precisely where you need it – in this case, under the single product description. The key hook we’ll be using is `woocommerce_after_single_product_summary`.
Method 1: Using the `functions.php` File (Recommended for Simple Changes)
This is the simplest method for adding small code snippets. It’s ideal for beginners and straightforward additions.
Reasoning: The `functions.php` file is part of your theme’s core. Adding code here keeps things centralized, making it easier to manage. However, be cautious! Updating your theme can overwrite changes made directly to `functions.php`. Always back up your code before making any modifications.
Steps:
1. Access your `functions.php` file: This typically resides in your theme’s folder (`wp-content/themes/[your-theme-name]/functions.php`). You can access it via your FTP client or your hosting’s file manager.
2. Add the following code: Place this code at the bottom of your `functions.php` file. Replace the placeholder comment with your desired code.
add_action( 'woocommerce_after_single_product_summary', 'my_custom_code_after_summary' );
function my_custom_code_after_summary() {
// Your code here! For example:
echo ‘
This is my custom text below the product description.
‘;
echo ‘
‘;
}
3. Save the file: Make sure to save your changes.
4. View your changes: Visit a product page on your website to see the results. Your custom text and elements should now appear below the product description.

add_action( 'woocommerce_after_single_product_summary', 'my_related_products' );
function my_related_products() {
woocommerce_related_products(); // This WooCommerce function displays related products.
}
This leverages an existing WooCommerce function, making things incredibly simple.
Method 2: Using a Custom Plugin (Recommended for Complex Code or Multiple Changes)
For larger code modifications or if you plan to add multiple custom elements, creating a custom plugin is the better approach.
Reasoning: Plugins are independent of your theme. This means they won’t be overwritten when you update your theme. It also keeps your code organized and makes it easier to manage and maintain.
Steps:
1. Create a plugin file: Create a new PHP file (e.g., `my-custom-woocommerce-code.php`) and place it in your `/wp-content/plugins/` directory.
2. Add the plugin header: At the top of your file, include the plugin header information:
<?php /**
- Plugin Name: My Custom WooCommerce Code
- Plugin URI: (your website)
- Description: This plugin adds custom code to WooCommerce single product pages.
- Version: 1.0.0
- Author: (Your Name)
- Author URI: (your website)
- License: GPL2
- License URI: https://www.gnu.org/licenses/gpl-2.0.html
- Text Domain: my-custom-woocommerce-code */
- No changes appear: Double-check your code for errors, ensure the hook name (`woocommerce_after_single_product_summary`) is correct, and that the plugin Read more about How To Edit Single Product Page In Woocommerce Theme Editor is activated (if using Method 2).
- Conflicting code: If you’re experiencing unexpected behavior, other plugins or themes might have conflicting code. Try deactivating other plugins temporarily to isolate the issue.
// Rest of your code will go here, similar to Method 1.
3. Add your code: Add the same code from Method 1 within this plugin file.
4. Activate the plugin: Go to your WordPress admin dashboard, navigate to Plugins, and activate your newly created plugin.
Troubleshooting
This guide provides a solid foundation for adding custom code under your WooCommerce single product pages. Remember to always back up your website before making any code changes, and choose the method (functions.php or a custom plugin) that best suits your needs and coding experience. Happy coding!
