How Can I Customize WooCommerce Templates Using Hooks and Template Overrides?

Using Hooks and Overriding Templates in WooCommerce

While customizing WooCommerce templates, you may have encountered situations where you wanted to modify specific elements within a template. This article will guide you through the correct approaches to achieving this.

Understanding Hooked Templates

WooCommerce templates are composed of multiple smaller templates that are hooked together using action hooks. For example, the woocommerce_single_product_summary hook contains multiple hooked templates, such as woocommerce_template_single_title, woocommerce_template_single_rating, and so on.

Overriding Templates vs. Editing Hooks

To modify a template, it's recommended to use the proper overriding mechanism rather than directly editing the template files in the plugin. Overriding templates allows you to make changes without affecting the core plugin files and simplifies future updates.

Customizing a Hooked Template

To customize a specific hooked template, you need to override the corresponding child template file. For instance, to customize the title of a single product page, you would find the woocommerce_template_single_title template in the single-product subdirectory and make changes to that file.

Using Action Hooks

If you wish to further customize the output of a hook, you can use WordPress action hooks. This involves creating a custom callback function and assigning it to the hook using the add_action() function. For example, you could add a custom string between the product price and description using the following function:

function my_custom_action() { 
    echo '<p>This is my custom action function</p>';
};     
add_action( 'woocommerce_single_product_summary', 'my_custom_action', 15 ); 

Maintaining the Template Structure

When customizing templates, ensure you maintain the existing template structure and only make necessary changes. Overriding specific templates or using custom action hooks allows you to make targeted modifications without disrupting the overall layout and functionality of the page.
