Enhance Your WooCommerce Store with Dynamic Discount Messages

When running an online store, it's crucial to incentivize customers to add more products to their cart. One effective way to do this is by displaying a message such as "Buy X more products to get a discount." This not only encourages more sales but also engages customers in an interactive manner. However, if you're using WooCommerce and want this message to update dynamically through AJAX when products are added or removed, it can get a bit tricky. In this guide, we will guide you through creating an AJAX-compatible WooCommerce shortcode that displays this dynamic discount message.

The Challenge

Initially, we set up a shortcode in WooCommerce to display a discount message based on the number of items in the cart. The code snippet below showcases the basic implementation of the shortcode:

This code works well for refreshing the message on the WooCommerce cart page, but when we introduce this shortcode using a sidebar widget, the message does not auto-refresh as expected. This happens even though you are utilizing AJAX to update the cart contents.

The Solution

To resolve this issue and ensure that your discount message updates dynamically with AJAX, we will leverage the woocommerce_add_to_cart_fragments filter hook, allowing us to modify the AJAX responses sent back to the browser. Let’s break down the steps to achieve this.

Step 1: Create a Custom Function for Discount Messages

You need to create a custom function that checks the number of items in the cart and generates the appropriate message. Here’s how to do that:

Shortcode Usage

You can now insert this shortcode into any page, product, or widget using:

In PHP: echo do_shortcode("[display_message]");

Step 4: Display the Message Through Hooks (Optional)

If you prefer to display the message through specific hooks instead of a shortcode, you can do so as follows:
