Adding custom fields to your WooCommerce checkout page gives you more control over the buying process. Instead of relying only on default details, you can collect extra information that makes order handling easier and improves customer satisfaction.
However, do you know how to add custom field in WooCommerce checkout page? If you know, congrats! If you don’t, we recommend you stick to the end of this article.
Here we shared two powerful methods to get this job done. Learn both methods and use the one you find suitable.
What Are Custom Checkout Fields?
Custom checkout fields are additional form fields you can add to your e-commerce checkout page to collect information beyond the standard details like name, address, and payment information. Think of them as custom questions you can ask your customers during the final step of their purchase.
While a standard checkout process gathers the essential data needed to process a payment and ship an order, custom fields allow you to design the checkout experience to meet your specific business needs. This extra information can be crucial for order fulfillment, customer service, or marketing.
Examples of Custom Checkout Fields
The possibilities are vast, but here are some of the most common and practical uses:
- Delivery Instructions: A text box for customers to leave notes for the delivery driver, such as “Leave the package at the back door” or “Beware of the dog.”
- Gift Messages: A textarea where a customer can type a personal message if the item is a gift. You could also add a checkbox asking, “Is this a gift?”
- Company or Tax ID: An input field for B2B (business-to-business) transactions where you need to collect a customer’s VAT number or Tax ID for invoicing.
- Survey Questions: A dropdown or set of radio buttons asking, “How did you hear about us?” to gather valuable marketing data.
- Age Verification: A required checkbox for customers to confirm they are over 18 before purchasing age-restricted products.
- File Uploads: A field that allows customers to upload a file, such as a design specification for a custom t-shirt or a logo for a personalized product.
By adding these fields, you can reduce the need for post-order communication and provide a more personalized and efficient service to your customers.
What Are the Benefits of Adding Custom Fields?
Customizing your WooCommerce checkout page with additional fields is more than just a technical tweak; it’s a strategic business decision that can significantly improve efficiency, customer satisfaction, and data collection.
Here are a few more benefits you’ll get by adding custom fields to your WooCommerce checkout page.
Improve Order Fulfillment
A smooth and accurate fulfillment process is the backbone of any e-commerce business. Custom fields help eliminate guesswork and reduce the back-and-forth communication that often follows an order.
- Gather Essential Delivery Information: Standard address forms don’t account for the nuances of every location.
A simple “Delivery Instructions” field allows customers to provide critical information like gate codes, apartment building access details, or where to leave a package safely.
- Specify Delivery Preferences: For businesses offering specialized delivery services, you can add fields for preferred delivery times or dates. This helps manage logistics more effectively and ensures a successful delivery on the first try.
Enhance Customer Experience
A personalized and frictionless checkout process makes customers feel valued and understood, encouraging them to complete their purchase and return in the future.
- Collect Gift Messages & Special Requests: If you sell products that are often purchased as gifts, adding a “Gift Message” field is essential.
It allows the buyer to add a personal touch directly at the point of sale. Similarly, fields for special requests or personalization details make the customer feel confident that their specific needs will be met.
- Reduce Post-Purchase Anxiety: When customers can provide all necessary information upfront, they feel more assured that their order will be handled correctly.
This clarity minimizes their need to contact customer support with additional instructions or questions, creating a seamless and positive experience.
Gather Valuable Marketing Data
The checkout page is a prime opportunity to learn more about your customers and how they found you. This first-party data is invaluable for refining your marketing strategy and optimizing your budget.
- Identify Effective Channels: A simple dropdown field asking, “How did you hear about us?” can provide direct insight into which marketing channels are driving sales. This helps you allocate your marketing spend more effectively.
- Collect Survey Information: You can use custom fields to ask quick questions about customer preferences or demographics.
You can use this data later for market segmentation, product development, and preparing future marketing campaigns for your audience.
Meet Legal & Business Requirements
For many businesses, collecting specific information at checkout isn’t just helpful. It’s mandatory for legal compliance and proper accounting.
- Fulfill B2B Obligations: If you sell to other businesses, you often need to collect Tax IDs or VAT numbers for invoicing and tax purposes.
Adding these required fields directly to the checkout form ensures you have the necessary information from the start. - Ensure Legal Compliance: For stores selling age-restricted items like alcohol or tobacco products, an age verification checkbox is a crucial legal safeguard.
This simple, required field confirms the customer meets the legal age for purchase, helping you operate responsibly and in accordance with the law.
How to Add Custom Field in WooCommerce Checkout Page: The No-Code Way
This method is highly recommended for beginners and anyone who wants a quick, visual way to manage checkout fields without touching code.
Step 1: Choose and Install a Plugin
First, you need to select a WordPress plugin that helps you easily add, edit, and delete custom fields from the WooCommerce checkout page. You can find many such kinds of plugins in the WordPress plugin repository.
However, the problem arises when you need to pick only one. Don’t worry. We have a recommendation. You can choose the ShopBuilder plugin. It’s a complete store builder that allows you to create or redesign your WooCommerce store with ease.
To install it, head over to Plugins >> Add Plugin from your WordPress Admin Interface.
Now, write ShopBuilder in the top right search bar and click Install Now button of the marked plugin in the screenshot below.
Now, press the Activate button to install the plugin.
That’s how you install and activate it.
Step 2: Turn on the Checkout Fields Editor
You now need to switch on the Checkout Fields Editor module of the ShopBuilder plugin. So, head to ShopBuilder >> Settings from your WP Admin Panel.
Click on the Modules tab and hit Checkout Fields Editor module.
You’ll now see a pop-up. Turn on Enable Checkout Fields Editor? switch.
You’ve successfully enabled the Checkout Fields Editor.
Step 3: Add a Custom Checkout Field
Let’s add a custom billing field. To do so, click on the Billing Fields tab and toggle on the Customize Billing Form? switch.
You’ll now notice all the billing fields of the checkout page. Look at the bottom left of the pop-up and hit Add Custom Field button.
Now, you’ll see an alert stating that this is a pro feature. That means you need the pro version of the plugin to utilize this feature.
Thus, get the pro version and follow the plugin installation steps to install and activate the ShopBuilder Pro. You’ll then be able to add a custom field.
Okay, after clicking the Add Custom Field button, turn on Enable Field? switch, write the field label and placeholder text, and finally, click Save Changes button.
That’s it. Now, visit the checkout page and you’ll see your desired field in the billing section of the checkout form.
How to Add Custom Field in WooCommerce Checkout Page Without Plugin: The Developer Way
We’ve seen how you can easily build a custom checkout field with the ShopBuilder plugin. But what if you don’t want to use any plugin? Instead, you prefer using code as a developer.
That’s why we created this section for people like you to make the job easier. Before you proceed with this developer-friendly method, don’t forget to back up your entire website and use only the child theme to apply this method.
Now, we need to insert a code snippet to create a custom checkout field into the functions.php file of the child theme. To do so, go to Appearance >> Theme File Editor from your WordPress Admin Panel if you use a classic theme.
Otherwise, you’ll find it under the Tools menu on your WP Admin Dashboard.
Locate the functions.php file and click on it.
Afterward, copy the code snippet below, paste it inside the theme file editor, and click Update File button.
Here’s the code snippet:
/**
* Add custom checkout field with validation
* Branded by RadiusTheme
*/
// 1. Display the custom field
add_action( 'woocommerce_after_order_notes', 'radiustheme_add_custom_checkout_field' );
function radiustheme_add_custom_checkout_field( $checkout ) {
woocommerce_form_field( 'delivery_instructions', array(
'type' => 'text',
'class' => array( 'form-row-wide' ),
'label' => __( 'Delivery Instructions', 'woocommerce' ),
'placeholder' => __( 'e.g. Leave package at the door', 'woocommerce' ),
'required' => true, // Set to false if optional
), $checkout->get_value( 'delivery_instructions' ) );
}
// 2. Validate the field
add_action( 'woocommerce_checkout_process', 'radiustheme_validate_custom_checkout_field' );
function radiustheme_validate_custom_checkout_field() {
if ( isset( $_POST['delivery_instructions'] ) && empty( $_POST['delivery_instructions'] ) ) {
wc_add_notice( __( 'Please enter your delivery instructions.', 'woocommerce' ), 'error' );
}
}
// 3. Save the field value to the order meta
add_action( 'woocommerce_checkout_update_order_meta', 'radiustheme_save_custom_checkout_field' );
function radiustheme_save_custom_checkout_field( $order_id ) {
if ( ! empty( $_POST['delivery_instructions'] ) ) {
update_post_meta( $order_id, 'delivery_instructions', sanitize_text_field( $_POST['delivery_instructions'] ) );
}
}
// 4. Display field value in the admin order details
add_action( 'woocommerce_admin_order_data_after_billing_address', 'radiustheme_display_custom_checkout_field_in_admin', 10, 1 );
function radiustheme_display_custom_checkout_field_in_admin( $order ) {
$value = get_post_meta( $order->get_id(), 'delivery_instructions', true );
if ( $value ) {
echo '<p><strong>' . __( 'Delivery Instructions', 'woocommerce' ) . ':</strong> ' . esc_html( $value ) . '</p>';
}
}You can now visit the checkout page to view the custom checkout field you’ve just created.
