Fixing the WooCommerce Ajax Add to Cart Quantity Issue

Have you ever faced a situation where your WooCommerce site correctly handles product quantities on the individual product pages, but fails to do so when using a custom product loop? If so, you're not alone. Many developers struggle with making AJAX add to cart functionalities work seamlessly within custom setups. In this guide, we'll dive deep into a common problem: the AJAX add to cart quantity not functioning as expected.

Understanding the Problem

In this scenario, a developer created a custom product loop using WP Bakery blocks to display products on the front page of a WooCommerce store. While the product quantity input worked flawlessly on individual product pages, it malfunctioned in the custom loop—only adding a quantity of 1 to the cart, regardless of what was selected by the user.

Common Symptoms of the Issue

Quantity Input Ignored: Regardless of how many items a customer selects, only one item is added to the cart.

No Error Messages: The functionality seems to load without any visible errors, making it harder to diagnose.

Step-by-Step Solution

Let's break down the solution into clear steps to address the issues and get your AJAX add to cart functioning properly again.

Step 1: Correctly Reference Post IDs

One of the key issues was an improper reference to the post ID within the loop. Instead of using $loop->post->ID, you should utilize the $post->ID variable after calling the_post().

Example Fix:

Replace all instances of:

Step 2: Update Product ID Retrieval

In the latest version of WooCommerce, it’s essential to retrieve the product ID using the method get_ID() instead of directly accessing the property. This ensures you are using the current best practices in WooCommerce.

Example Fix:

Change:

Step 3: Integrate Quantity Change Functionality

To ensure the quantity input works dynamically, you will need to attach a small jQuery script to update the button's data-quantity attribute when the quantity input changes.

Example Code:

Add this jQuery script towards the end of your custom loop:
