How to Ajaxify Header Cart Items Count in WooCommerce: A Step-by-Step Guide

Ajaxify Header Cart Items Count in WooCommerce

Introduction

Updating the header cart items count without reloading the page enhances user experience. Let's delve into the problem and its solution.

Problem Statement

The goal is to dynamically get the total number of cart items from the server using jQuery. However, the current implementation faces difficulty when multiple items are added simultaneously.

Solution

1. Using the dedicated WooCommerce hook

Instead of manual reload, utilize the woocommerce_add_to_cart_fragments action hook, which is powered by Ajax:

  • Embed the cart count in HTML with a unique ID or class, e.g.
    ...
    .
  • Add the following code to your functions.php:
<code class="php">add_filter('woocommerce_add_to_cart_fragments', 'wc_refresh_mini_cart_count');
function wc_refresh_mini_cart_count($fragments) {
    ob_start();
    $items_count = WC()->cart->get_cart_contents_count();
    ?>
    <div id="mini-cart-count"><?php echo $items_count ? $items_count : ' '; ?></div>
    <?php
    $fragments['#mini-cart-count'] = ob_get_clean();
    return $fragments;
}</code>

2. Using jQuery to force refresh

If necessary, force refresh the count using delegated events:

<code class="javascript">$(document.body).trigger('wc_fragment_refresh');</code>

or

<code class="javascript">$(document.body).trigger('wc_fragments_refreshed');</code>

Benefits

  • Avoid unnecessary reloads.
  • Dynamically update the cart count with each item addition or removal.
  • Enhance user experience by providing real-time feedback.
