This Is How to Modify Shipping in WooCommerce Cart With a Custom AJAX Solution
One of the key aspects of an ecommerce website is the shopping cart and checkout process. Allowing customers to easily update their cart contents, including the shipping options, is crucial for providing a smooth user experience and maximizing conversions.
In WooCommerce, the default cart and checkout functionality works well in most cases. However, if your theme doesn't have built-in AJAX support for updating the cart, you may need to create a custom AJAX solution to make changes to the shipping section.
In this article, we'll walk you through the step-by-step process of creating a custom AJAX solution to modify the shipping options in your WooCommerce cart. By the end, you'll have a fully functional system that allows your customers to update the shipping details without a full page refresh.
Why AJAX is Important for Cart Updates
AJAX (Asynchronous JavaScript and XML) is a web development technique that allows parts of a web page to be updated dynamically, without requiring a full page refresh. This is particularly useful for ecommerce sites, where customers need to be able to quickly and easily update their cart contents.
Without AJAX, every time a customer wants to change the shipping option or quantity in their cart, the entire page would need to reload. This can create a frustrating user experience, leading to abandoned carts and lost sales.
By using AJAX, you can update the cart contents and shipping options on the fly, providing a more seamless and responsive shopping experience for your customers. This can have a significant impact on your conversion rates and overall customer satisfaction.
The Problem with WooCommerce and Shipping Modifications
The default WooCommerce cart and checkout functionality works well in many cases, but it doesn't always provide the level of flexibility and customization that some store owners require.
One common issue is the ability to modify the shipping options in the cart. By default, WooCommerce uses the built-in WordPress AJAX functionality to update the cart contents, including the shipping options. However, some WordPress themes may not have this AJAX functionality enabled, or may have their own custom AJAX implementation that conflicts with the default WooCommerce behavior.
In these cases, you'll need to create a custom AJAX solution to ensure that your customers can update the shipping options in the cart without a full page refresh.
Step-by-Step Guide to Creating a Custom AJAX Solution
To create a custom AJAX solution for modifying the shipping options in your WooCommerce cart, follow these steps:
1. Enqueue the AJAX Script
First, you'll need to enqueue your custom AJAX script in your WordPress theme. You can do this by adding the following code to your theme's functions.php
file:
function my_custom_ajax_script() {
wp_enqueue_script( 'my-custom-ajax', get_template_directory_uri() . '/js/my-custom-ajax.js', array( 'jquery' ), '1.0.0', true );
// Pass the AJAX URL to the JavaScript file
wp_localize_script( 'my-custom-ajax', 'myAjax', array(
'url' => admin_url( 'admin-ajax.php' ),
));
}
add_action( 'wp_enqueue_scripts', 'my_custom_ajax_script' );
This code will enqueue your custom AJAX script, my-custom-ajax.js
, and pass the AJAX URL to the script using the wp_localize_script()
function.
2. Create the AJAX Callback Function
Next, you'll need to create the AJAX callback function that will handle the cart updates. This function will be called when the AJAX request is made, and will update the shipping options in the cart.
Add the following code to your theme's functions.php
file:
function my_custom_ajax_callback() {
// Verify the AJAX request
check_ajax_referer( 'my-custom-ajax-nonce', 'security' );
// Get the updated cart contents
WC()->cart->calculate_totals();
// Render the updated cart contents
ob_start();
woocommerce_cart_totals();
$cart_totals = ob_get_clean();
ob_start();
woocommerce_cart_shipping_method_total();
$shipping_total = ob_get_clean();
// Return the updated HTML
wp_send_json_success( array(
'cart_totals' => $cart_totals,
'shipping_total' => $shipping_total,
));
}
add_action( 'wp_ajax_my_custom_ajax_callback', 'my_custom_ajax_callback' );
add_action( 'wp_ajax_nopriv_my_custom_ajax_callback', 'my_custom_ajax_callback' );
This code defines the my_custom_ajax_callback()
function, which is responsible for handling the AJAX request. It first verifies the AJAX request using the check_ajax_referer()
function, then updates the cart totals and renders the updated cart contents and shipping total using the WooCommerce template tags.
Finally, it returns the updated HTML as a JSON response, which will be used by the client-side JavaScript to update the cart display.

3. Create the Client-side JavaScript
Now that you have the server-side AJAX callback function set up, you can create the client-side JavaScript to handle the AJAX request and update the cart display.
Create a new file, my-custom-ajax.js
, in your theme's js
directory, and add the following code:
jQuery(document).ready(function($) {
// Add the AJAX event listener to the shipping form
$('body').on('change', 'select.shipping_method', function() {
// Get the selected shipping method
var shippingMethod = $(this).val();
// Prepare the AJAX data
var data = {
action: 'my_custom_ajax_callback',
security: myAjax.url,
shipping_method: shippingMethod,
};
// Send the AJAX request
$.ajax({
url: myAjax.url,
type: 'POST',
data: data,
success: function(response) {
if (response.success) {
// Update the cart totals and shipping total
$('.cart-totals').html(response.data.cart_totals);
$('.shipping-total').html(response.data.shipping_total);
}
},
error: function(xhr, status, error) {
console.error(error);
}
});
});
});
This JavaScript code adds an event listener to the shipping method dropdown in the cart, and sends an AJAX request to the my_custom_ajax_callback()
function whenever the selected shipping method is changed.
The AJAX request includes the selected shipping method as data, and the server-side function my_custom_ajax_callback()
uses this information to update the cart totals and shipping total. The updated HTML is then returned to the client-side, where it is used to update the cart display.
4. Render the Updated Cart Contents
Finally, you'll need to update your theme's cart template to display the updated cart contents and shipping total. In your theme's cart.php
file, replace the following lines:
<?php woocommerce_cart_totals(); ?>
<?php woocommerce_cart_shipping_method_total(); ?>
with the following code:
<div class="cart-totals">
<?php woocommerce_cart_totals(); ?>
</div>
<div class="shipping-total">
<?php woocommerce_cart_shipping_method_total(); ?>
</div>
This will wrap the cart totals and shipping total in separate div
elements, which can be targeted by the AJAX response to update the cart display.
