How to Show an Add Warranty Option in WooCommerce Cart Total
Introduction:
Offering product warranties is a great way to build customer trust and increase sales in your WooCommerce store. By Learn more about How To Change Product Thumbnail Size In Woocommerce 2019 providing customers with the option to purchase a warranty, you reassure them about the quality and reliability of your products. Many customers are more likely to buy a product if they know they’re covered in case something goes wrong. While WooCommerce doesn’t natively include a warranty option in the cart total, you can easily implement this feature using custom code or plugins. This article will guide you through the process of adding a warranty option that displays alongside the cart total, enhancing the user experience and potentially boosting your revenue. Let’s delve into how to do it!
Adding a Warranty Option
There are two primary approaches to adding a warranty option to your WooCommerce cart total: using a plugin or implementing custom code. We’ll focus on a custom code solution, providing you with the flexibility to tailor the warranty offering to your specific needs.
Custom Code Implementation
This method involves adding custom PHP code to your theme’s `functions.php` file or a custom plugin. Always back up your website before making any code changes. Incorrect code can break your site.
Step 1: Define the Warranty Option
First, we need to define the warranty option and its associated cost. For this example, let’s offer a one-year warranty for 10% of the cart subtotal.
Step 2: Add the Learn more about How To Reorder Woocommerce Product Attributes Warranty Field to the Cart
We’ll use the `woocommerce_cart_calculate_fees` action to add the warranty option to the cart.
add_action( 'woocommerce_cart_calculate_fees','add_warranty_option' ); function add_warranty_option( $cart ) { if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;
$warranty_cost_percentage = 0.1; // 10% of subtotal
$subtotal = $cart->subtotal;
$warranty_cost = $subtotal * $warranty_cost_percentage;
WC()->cart->add_fee( ‘Warranty (1 Year)’, $warranty_cost, true );
}
- This code snippet hooks into the `woocommerce_cart_calculate_fees` action.
- It calculates the warranty cost as 10% of the cart subtotal.
- `WC()->cart->add_fee()` adds the warranty as a fee in the cart.
- The third argument `true` specifies that the amount is taxable. Change to `false` if it is not.
Step 3: Displaying the Warranty Option
The previous code will automatically add the warranty option and display it alongside the cart total. However, if you want more control or to offer users a choice, you can add a checkbox or radio button to let them select the warranty.
Here’s an example of how you might achieve this by adding a hidden custom field and modifying the code from Step 2:
add_action( 'woocommerce_before_cart', 'add_warranty_checkbox' ); function add_warranty_checkbox() { echo ''; }
add_action( ‘woocommerce_cart_calculate_fees’,’add_warranty_option_conditional’ );
function add_warranty_option_conditional( $cart ) {
if ( is_admin() && ! defined( ‘DOING_AJAX’ ) )
return;
if ( isset($_POST[‘add_warranty’]) && $_POST[‘add_warranty’] == 1 ) {
$warranty_cost_percentage = 0.1; // 10% of subtotal
$subtotal = $cart->subtotal;
$warranty_cost = $subtotal * $warranty_cost_percentage;
WC()->cart->add_fee( ‘Warranty (1 Year)’, $warranty_cost, true );
}
}
// Store warranty option in the session so it persists
add_action( ‘woocommerce_cart_loaded_from_session’, ‘restore_warranty_from_session’ );
function restore_warranty_from_session( $cart ) {
if ( ! WC()->session->has_session() ) return;
if ( WC()->session->get( ‘add_warranty’ ) ) {
$_POST[‘add_warranty’] = WC()->session->get( ‘add_warranty’ );
}
}
// Update the session when cart is updated
add_action( ‘woocommerce_update_cart_action_cart_updated’, ‘update_warranty_session’ );
function update_warranty_session() {
if ( isset( $_POST[‘add_warranty’] ) ) {
WC()->session->set( ‘add_warranty’, $_POST[‘add_warranty’] );
} else {
WC()->session->set( ‘add_warranty’, null );
}
}
- The first function adds a checkbox before the cart.
- The second function conditionally adds the warranty fee only if the checkbox is checked.
- The `restore_warranty_from_session` function makes the warranty selection persistent across cart page reloads.
- The `update_warranty_session` function saves the checkbox state in the session whenever the cart is updated.
Important: This code relies on `$_POST[‘add_warranty’]` being set when the cart is recalculated. WooCommerce cart updates are typically handled via AJAX. This implementation might not work perfectly “out of the box” due to the AJAX nature of cart updates. You will likely need to trigger a cart update when the checkbox is changed using Javascript. Consider using a robust plugin for a more seamless user experience.
Step 4: Adding JavaScript to Handle Cart Updates (Requires more advanced customization)

jQuery(document).ready(function($) {
$(‘input[name=”add_warranty”]’).on(‘change’, function() {
// Trigger an update of the cart
$(‘[name=”update_cart”]’).trigger(‘click’); // This may vary depending on your theme!
});
});
- This JavaScript code adds a change event listener to the warranty checkbox.
- When the checkbox is changed, it triggers the cart update button. This may need adjustment based on your theme’s implementation.
Advantages of Custom Code:
- Flexibility: You have complete control over the warranty option.
- Cost-effective: No need to pay for a premium plugin.
- Learning opportunity: Understand how WooCommerce works under the hood.
Disadvantages of Custom Code:
- Complexity: Requires PHP and potentially JavaScript knowledge.
- Maintenance: You are responsible for maintaining the code.
- Compatibility: May break with theme or WooCommerce updates.
- AJAX cart updates complexity: Getting the checkbox to work seamlessly with AJAX updates requires advanced knowledge.
Using a Plugin
Another option to display an add warranty option in woocommerce cart is using a plugin. There are several plugins available that offer warranty features for WooCommerce. These plugins often provide a user-friendly interface and may include additional functionalities like warranty management and reporting.
Some Popular WooCommerce Warranty Plugins:
- Product Warranty Manager for WooCommerce
- YITH WooCommerce Product Add-ons (can be configured for warranties)
Advantages of Using Plugins:
- Ease of use: Typically, plugins offer a straightforward configuration process.
- Features: Many plugins offer advanced features.
- Support and updates: Plugin developers provide support and updates.
Disadvantages of Using Plugins:
- Cost: Premium plugins can be expensive.
- Bloat: Some plugins add unnecessary code and slow down your site.
- Compatibility: Ensure the plugin is compatible with your theme and other plugins.
Conclusion:
Adding a warranty option to your WooCommerce cart total can significantly enhance the customer experience and increase sales. Whether you choose to implement a custom code solution or use a plugin, carefully consider the pros and cons of each approach. If you’re comfortable with PHP and JavaScript, a custom solution provides greater flexibility. However, for users who prefer a simpler approach with pre-built features, a plugin may be the better option. Remember to always test your implementation thoroughly and back up your website before making any changes. Adding that extra layer of reassurance can be a powerful conversion tool.
