WooCommerce Single Product Page Hooks: The Ultimate Guide

If you’re customizing WooCommerce for your WordPress site , understanding single product page hooks is essential. This comprehensive guide will walk you through every important hook available on the WooCommerce single product page, complete with examples and implementation tips.

Introduction to WooCommerce Hooks

WooCommerce uses WordPress’s action and filter hook system extensively to allow developers to modify functionality without editing core files. For single product pages, these hooks provide precise control over every element’s placement and appearance.

Why Use WooCommerce Single Product Hooks?

1. Customize product page layout without modifying template files
2. Add/remove content at specific locations
3. Modify default WooCommerce behavior
4. Integrate third-party plugins seamlessly
5. Optimize for conversions by rearranging elements

Complete List of Single Product Page Hooks

These fire before the main product content begins.

/**
 * Fires before the single product content
 */
do_action( 'woocommerce_before_single_product' );

/**
 * Fires before the single product summary container
 */
do_action( 'woocommerce_before_single_product_summary' );

Usage Example:

add_action( 'woocommerce_before_single_product', function() {
    echo '<div class="product-notice">Limited time offer!</div>';
});

2. Product Image Hooks

Control the product image gallery display.

/**
 * Fires before the product image
 */
do_action( 'woocommerce_product_thumbnails' );

Usage Example:

function add_video_to_gallery() {
    // Add product video after thumbnails
    echo '<div class="product-video">...</div>';
}

3. Product Summary Hooks

These control the main product details area.
