How to Set Up Advanced Product Filtering in WooCommerce – 2024

In an online store, enabling customers to quickly find products that meet their needs is crucial for improving user experience and boosting sales. Advanced product filtering is an essential feature for any WooCommerce store, especially those with a large inventory or varied product ranges. In this blog post, we’ll explore how to set up advanced product filtering in WooCommerce to help customers efficiently navigate through products.

Why Advanced Product Filtering Is Important

Effective product filtering reduces the time customers spend searching for products, which can directly influence their buying decisions and overall satisfaction. By implementing advanced product filtering in WooCommerce, you can offer a more personalized shopping experience, allowing customers to filter products by multiple attributes such as size, color, price, and more.

Step-by-Step Guide to Implement Advanced Product Filtering in WooCommerce

Step 1: Define Relevant Product Attributes

Before adding filters, identify the attributes that are most significant to your customers. Common attributes include size, color, price, material, and brand. In WooCommerce, you can add these attributes under Products > Attributes in the dashboard.

Step 2: Add Attributes to Products

Once you’ve defined your attributes, assign them to your products. This can be done in the product editing page under the “Attributes” section. Make sure to mark the attributes as visible on the product page and usable for filtering.

*/ function wcsuccess_add_attributes_to_products() { // Assuming 'color' is a registered attribute $product_id = 25; // Example product ID $attributes = array( 'color' => array( // Terms of the attribute 'terms' => array('red', 'blue'), 'visible' => true, 'variation' => false, ) ); update_post_meta($product_id, '_product_attributes', $attributes); } add_action('init', 'wcsuccess_add_attributes_to_products');

Step 3: Enable Filtering by Attributes

Go to Appearance > Widgets, and add the “Filter Products by Attribute” widget to your shop sidebar. This allows customers to filter products by one or more attributes you’ve set up.

Step 4: Customize the Filtering Experience

To improve the customer experience, customize the appearance and functionality of your filters. This could involve adding dropdowns, checkboxes, or sliders for attributes like price ranges.

Let’s say you want to make the attribute filtering smoother by implementing dropdowns that automatically update the product grid without needing to hit a ‘submit’ button. You’ll need to handle events where the dropdown selection changes and then trigger the filtering.

Example JavaScript File: custom-filter-ui.js

document.addEventListener('DOMContentLoaded', function() {
    // Listen for changes on each dropdown filter
    document.querySelectorAll('.widget_layered_nav select').forEach(function(select) {
        select.addEventListener('change', function() {
            // Assuming the shop page URL or a specific part of the site needs to be updated
            var selectedOption = select.value;
            var baseUrl = window.location.href.split('?')[0];
            var newUrl = baseUrl + '?filter_' + + '=' + selectedOption;

            // Redirect to the new URL with the selected filter option
            window.location.href = newUrl;


  1. Event Listener: The script starts by waiting for the entire content of the page to load (DOMContentLoaded). This ensures all elements are fully loaded before attaching event listeners.
  2. Selecting Elements: It selects all <select> elements within widgets designed for layered navigation (assuming these are dropdowns generated for attributes).
  3. Handling Changes: It adds an event listener to each dropdown. When a user changes the selection (i.e., chooses a filter option), the script constructs a new URL based on the current base URL and the selected filter value.
  4. Redirecting: Finally, the script redirects the browser to the new URL, which includes the selected filter parameter. This would trigger WooCommerce to display filtered results based on the attribute chosen.

Step 5: Test and Optimize

Finally, test your filters thoroughly to ensure they work correctly across all devices. Collect customer feedback to understand their experience with the filters and make adjustments as needed.
