Add WooCommerce Custom Fields in the Registration Form

To achieve it, you need to follow these steps:

  • Firstly, Enable WooCommerce Registration Form
  • Secondly, Add Custom Field in WooCommerce Registration Form
  • Add Custom Fields to the Frontend
  • Add Validations to Custom Fields
  • Finally, Save the Data of Custom Fields to the Database

Enable WooCommerce Registration Form

Open your WordPress admin panel and navigate to WooCommerce → Settings from the left side of the dashboard:

Now here, first click on Account & Privacy tab and then select the checkbox Allow customers to create an account on the “My Account” page:

Then click on Save Changes from the bottom of this page:

Finally, Go to the account page, and you will see the default WooCommerce registration form:

Add WooCommerce Custom Fields in the Registration Form

Navigate to Appearance → Editor from the left side of your dashboard:

On the right side, you will see the Theme Files section, here click on functions.php to open this file:

Now you will see the editor for your functions.php file:

From here, you will add the custom fields in WooCommerce Register Form.

Add Custom Fields to the Frontend

First, add your custom fields to the front end of your WooCommerce Registration Form. So, to do it, add this code at the end of functions.php:

function woocom_extra_register_fields() {?>

<p class=”form-row form-row-wide”>

<label for=”reg_billing_first_name”><?php _e( ‘First name’, ‘woocommerce’ ); ?><span class=”required”>*</span></label><input type=”text” class=”input-text” name=”billing_first_name” id=”reg_billing_first_name” value=”<?php if ( ! empty( $_POST[‘billing_first_name’] ) ) esc_attr_e( $_POST[‘billing_first_name’] ); ?>” /></p>

<p class=”form-row form-row-wide”>

<label for=”reg_billing_last_name”><?php _e( ‘Last name’, ‘woocommerce’ ); ?><span class=”required”>*</span></label><input type=”text” class=”input-text” name=”billing_last_name” id=”reg_billing_last_name” value=”<?php if ( ! empty( $_POST[‘billing_last_name’] ) ) esc_attr_e( $_POST[‘billing_last_name’] ); ?>” /></p>



add_action( ‘woocommerce_register_form_start’, ‘woocom_extra_register_fields’ );

In the above code, I have created the function woocom_extra_register_fields() in which I have added the fields (First Name and Last Name), which will show in the front end. You can add more fields according to your need.

I have also added the prefix “billing_” before the name of each custom field to relate it with the billing address. So, here is a list of all the valid fields which you can add to your WooCommerce registration form, and they can be up with the billing address:

  • billing_first_name
  • billing_last_name
  • billing_address_1
  • billing_address_2
  • billing_phone
  • billing_company
  • billing_city
  • billing_postcode
  • billing_country
  • billing_state
  • billing_email

Now to verify that the fields are correctly up to your WooCommerce Registration Form, go to your store account page, and here you will see them:

Add Validations to Custom Fields

As your WooCommerce Registration Form fields are up, now to add validation to these fields. So, add this code after the end of the previous function:

function woocom_validate_extra_register_fields( $username, $email, $validation_errors )


if (isset($_POST[‘billing_first_name’]) && empty($_POST[‘billing_first_name’]) ) {

$validation_errors->add(‘billing_first_name_error’, __(‘First Name is required!’, ‘woocommerce’));


if (isset($_POST[‘billing_last_name’]) && empty($_POST[‘billing_last_name’]) ) {

$validation_errors->add(‘billing_last_name_error’, __(‘Last Name is required!’, ‘woocommerce’));


return $validation_errors;


add_action(‘woocommerce_register_post’, ‘woocom_validate_extra_register_fields’, 10, 3);

In the above code. I have created the function woocom_validate_extra_register_fields( $username, $email, $validation_errors ) in which I have set validation that if the created custom fields are empty, then show the message. I have set this message:

  • First name field, First Name is required!
  • Last name field, the Last Name is required!

Save the Data of Custom Fields to the Database

function woocom_save_extra_register_fields($customer_id) {

if (isset($_POST[‘billing_first_name’])) {

update_user_meta($customer_id, ‘billing_first_name’, sanitize_text_field($_POST[‘billing_first_name’]));


if (isset($_POST[‘billing_last_name’])) {

update_user_meta($customer_id, ‘billing_last_name’, sanitize_text_field($_POST[‘billing_last_name’]));



add_action(‘woocommerce_created_customer’, ‘woocom_save_extra_register_fields’);

In the above code. I have created the function woocom_save_extra_register_fields($customer_id)  which will save the data of the custom fields in the database.

All done, click on Update File from the bottom of the Editor:

It’s time to verify whether the data of the custom fields are getting saved in the database. Register the account and then go to your billing address to check it. Here you will see that the first name and last name are added automatically to the billing address:
