How to add the additional fields on the account creation form — WooCommerce?

To allow customers to create an account, you may need to add additional fields on the WordPress form.  By default, WooCommerce offers the option to activate the “Email address” and “password” fields. However, these fields are frequently not representative of business realities. So, we will see how to add the fields that interest us. This is without having to install an extension.

Follow the steps below to add an extra field to WooCommerce registration form

To add an extra field to the WooCommerce registration form, you can follow these steps:

• Open your WordPress dashboard and navigate to the “Appearance” section.
• Select “Theme Editor” from the drop-down menu.
• In the list of theme files on the right side of the screen, select “functions.php”.
• Scroll to the bottom of the “functions.php” file and add the following code:

<?php 
// Add new field to registration form
add_action( 'woocommerce_register_form', 'add_extra_registration_field' );
function add_extra_registration_field() {
?>
    <p class="form-row form-row-wide">
        <label for="extra_field"><?php _e( 'Extra Field', 'woocommerce' ); ?> <span class="required">*</span></label>
        <input type="text" class="input-text" name="extra_field" id="extra_field" value="<?php if ( ! empty( $_POST['extra_field'] ) ) esc_attr_e( $_POST['extra_field'] ); ?>" />
    </p>
<?php
}

// Validate the new field
add_action( 'woocommerce_register_post', 'validate_extra_registration_field', 10, 3 );
function validate_extra_registration_field( $username, $email, $validation_errors ) {
    if ( isset( $_POST['extra_field'] ) && empty( $_POST['extra_field'] ) ) {
        $validation_errors->add( 'extra_field_error', __( 'Please provide a value for the extra field', 'woocommerce' ) );
    }
}

// Save the new field
add_action( 'woocommerce_created_customer', 'save_extra_registration_field' );
function save_extra_registration_field( $customer_id ) {
    if ( isset( $_POST['extra_field'] ) ) {
        update_user_meta( $customer_id, 'extra_field', sanitize_text_field( $_POST['extra_field'] ) );
    }
}

• Save the changes in the “functions.php” file.

This code will add a new field called “Additional Field” to the WooCommerce registration form. It will also validate the field to ensure it is not left blank and save the field value to the user’s metadata upon signup. You can customize the field label and validation message by modifying the text in the add_extra_registration_field() and validate_extra_registration_field() functions, respectively.

Use a WordPress plugin

If you are not familiar with PHP programming, you can use an extension to perform the same task. For this, below are some extensions we recommend.

However, it should be noted that these extensions may have a price.
