Introduction:
WooCommerce provides a fantastic suite of e-commerce functionality right out of the box. One of its visual enhancements is PrettyPhoto, a lightbox script used for displaying product images in a more engaging way. While WooCommerce handles PrettyPhoto for its core elements, you might need to extend its use to custom elements within your theme or plugins. This article will guide you through how to integrate and utilize WooCommerce PrettyPhoto in your custom theme’s `functions.php` file, ensuring seamless integration and improved user experience.

Integrating PrettyPhoto with Your Custom Theme
The following steps outline how to incorporate PrettyPhoto functionality into your custom theme via `functions.php`.
Step 1: Check for WooCommerce Existence
Before you start fiddling with WooCommerce-related functions, it’s crucial to ensure WooCommerce is actually installed and active. This prevents errors and ensures your code runs only when WooCommerce is present.
<?php
if ( class_exists( ‘WooCommerce’ ) ) {
// WooCommerce is active! Proceed with PrettyPhoto integration.
add_action( ‘wp_enqueue_scripts’, ‘enqueue_custom_prettyphoto’ );
}
Step 2: Enqueue the Necessary Scripts
WooCommerce typically enqueues PrettyPhoto by default. However, if it’s not working as expected or you’re targeting specific elements, you might need to enqueue it manually. You should also enqueue custom script to use prettyphoto.
Create a new file `your-theme/assets/js/custom-prettyphoto.js` with next code:
jQuery(document).ready(function($){
$(“a[rel^=’prettyPhoto’]”).prettyPhoto();
});
Then, include your custom script with prettyPhoto script:
<?php
/
* Enqueue PrettyPhoto and custom script.
*/
function enqueue_custom_prettyphoto() {
wp_enqueue_script( ‘prettyphoto’, get_template_directory_uri() . ‘/woocommerce/assets/js/prettyPhoto/jquery.prettyPhoto.min.js’, array( ‘jquery’ ), ‘3.1.6’, true );
wp_enqueue_style( ‘prettyphoto’, get_template_directory_uri() . ‘/woocommerce/assets/js/prettyPhoto/css/prettyPhoto.css’ );
// Enqueue custom script that uses prettyphoto
wp_enqueue_script( ‘custom-prettyphoto’, get_stylesheet_directory_uri() . ‘/assets/js/custom-prettyphoto.js’, array(‘jquery’, ‘prettyphoto’), ‘1.0’, true );
}
Explanation:
- `wp_enqueue_script()`: This function registers and enqueues the PrettyPhoto JavaScript file. We set `’jquery’` as a dependency, ensuring jQuery is loaded first. The `true` argument places the script in the footer for better performance.
- `wp_enqueue_style()`: This function registers and enqueues the PrettyPhoto CSS stylesheet.
- `custom-prettyphoto.js` file contains jQuery code to apply prettyPhoto
- Path: Replace `get_template_directory_uri()` and `get_stylesheet_directory_uri()` with the correct paths to the PrettyPhoto files within your theme or child theme. It’s recommended to place the PrettyPhoto files (both CSS and JS) in a dedicated folder, such as `/woocommerce/assets/js/prettyPhoto/` within your theme.
- Version: Check the version of PrettyPhoto used by your WooCommerce installation (usually found in the WooCommerce plugin folder or in the enqueued scripts). Update the version number in `wp_enqueue_script()` accordingly.
- `href`: This attribute specifies the path to the large version of the image that you want to display in the lightbox.
- `rel=”prettyPhoto”`: This is the key attribute that tells PrettyPhoto to handle the link.
- For a gallery, use `rel=”prettyPhoto[gallery_name]”`. All images with the same `gallery_name` will be grouped into a gallery.
- Conflicting JavaScript: Other JavaScript libraries or scripts on your site might conflict with PrettyPhoto. Use the browser’s developer console to identify any JavaScript errors. Potential solutions include using `jQuery.noConflict()`, namespacing your custom code, or ensuring that PrettyPhoto is loaded before any conflicting scripts.
- CSS Conflicts: Your theme’s CSS might override the PrettyPhoto styles, causing visual issues. Use your browser’s developer tools to inspect the elements and identify conflicting styles. Adjust your theme’s CSS to ensure PrettyPhoto is displayed correctly.
- PrettyPhoto Version: If PrettyPhoto is updated, you will need to update the version number in your `functions.php` file and potentially adjust your code to be compatible with the newer version.
- Performance: Loading too many images or large images in the lightbox can affect performance. Optimize your images for the web to reduce file sizes and loading times.
Important:
Step 3: Implement PrettyPhoto in Your Custom Elements
Now that PrettyPhoto is enqueued, you can apply it to your custom elements. This usually involves adding the `rel=”prettyPhoto”` attribute to your anchor tags.
Explanation:
Step 4: Customize PrettyPhoto Options (Optional)
PrettyPhoto offers various customization options. You can pass these options through the JavaScript initialization. For example, to change the animation speed and theme, you would modify your `custom-prettyphoto.js` file to this:
jQuery(document).ready(function($){
$(“a[rel^=’prettyPhoto’]”).prettyPhoto({
animationSpeed:’fast’, /* fast/slow/normal */
theme:’light_square’, /* light_square / dark_square / light_rounded / dark_rounded / default */
});
});

Example Scenario: Integrating PrettyPhoto with Custom Product Tabs
Let’s say you’ve added a custom product tab that displays additional images. You’d want those images to open in a lightbox.
1. Add the images with the `rel` attribute: Within the code that generates your custom tab content, ensure that your image links have the `rel=”prettyPhoto”` attribute. For a gallery in the custom tab, use `rel=”prettyPhoto[custom_tab_gallery]”`.
2. Verify Script Enqueueing: Double-check that your `enqueue_custom_prettyphoto()` function is correctly enqueueing the PrettyPhoto scripts. If not, you’ll need to debug why the script isn’t being loaded.
Potential Issues and Considerations
Conclusion:
Integrating WooCommerce PrettyPhoto into your custom theme’s `functions.php` allows you to seamlessly extend its lightbox functionality to custom elements, improving user experience and showcasing your products in a visually appealing way. By carefully following the steps outlined in this guide, you can successfully enqueue the necessary scripts, implement the `rel` attribute, and customize the PrettyPhoto options to match your theme’s design. Remember to address potential issues like JavaScript or CSS conflicts to ensure a smooth and functional integration. By leveraging PrettyPhoto, you can significantly enhance the visual presentation of your WooCommerce store.
