Adding PHP to the Top of WooCommerce Category Pages: A Beginner’s Guide
Want to add custom functionality to your WooCommerce category pages? Perhaps you need a special message, a custom form, or extra styling? Adding PHP code to the top of these pages is the way to go. This guide will walk you through the process, explaining everything in a simple, step-by-step manner, perfect for beginners.
Why would you need to add PHP to your WooCommerce category pages?
Let’s say you’re running a clothing store. You might want to display a special offer banner at the top of your “Sale” category page. Or, imagine you want a unique filter specifically for your “Shoes” category. These are perfect scenarios for adding custom PHP.
Understanding the Method: Using a Child Theme
The most important thing to remember when modifying WooCommerce (or WordPress in general) is to use a child theme. This ensures your changes aren’t overwritten when you update your main theme. If you haven’t already created a child theme, do that first! There are plenty of tutorials online to guide you through this crucial step.
The Code: Adding a Simple Message
Let’s start with a simple example: adding a message to the top of our category pages. We’ll use the `woocommerce_archive_description` hook.
This hook lets us add content *before* the standard category description.
<?php /**
- Add a message to the top of WooCommerce category pages. */ add_action( 'woocommerce_archive_description', 'my_custom_category_message', 10, 1 );
- No Changes Appearing: Double-check that you’ve saved the `functions.php` file and that it’s in the correct location (your child theme’s directory). Clear your browser cache and try again.
- Incorrect Placement: The `woocommerce_archive_description` hook places the content *before* the existing category description. Use a different hook if you Check out this post: How To Find My Store On Woocommerce need to place content elsewhere.
- Conflicting Plugins: A plugin might be interfering with your code. Try deactivating plugins one by one to identify the culprit.
function my_custom_category_message( $description ) {
echo ‘
‘;
return $description; //Important to return the original description
}
?>
1. `add_action()`: This line adds our custom function (`my_custom_category_message`) to the `woocommerce_archive_description` hook. The `10` is the priority (lower numbers run first), and `1` indicates the number of parameters the function accepts.
2. `my_custom_category_message()`: This function echoes our custom message inside a `
3. Where to put this code: Create a new file (e.g., `functions.php`) in your child theme’s folder and paste this code into it.
Adding More Complex Functionality
The above example is simple, but you can add much more complex functionality. Let’s say you want to display the number of products in the category:
found_posts; echo 'This category contains ' . $product_count . ' products!'; return $description; } ?>
This updated code uses `$wp_query->found_posts` to get the number of products and dynamically inserts it into the message.
