About This Solution

This guide shows you how you can add a custom text field on the registration form on the My Account page. In this specific example, we ask for the user’s license plate number. If empty, a custom error is shown. If validated properly, the text field is saved to the database as user meta and shown in the user profile editor in the WordPress Dashboard.

// Create the new license plate text field
add_action( 'woocommerce_register_form', 'ecommercehints_register_text_form_field' );
function ecommercehints_register_text_form_field() {
			'type'        => 'text',
			'required'    => true, // If true show an asterisk (*)
			'label'       => 'Vehicle License Plate',
			'description' => 'Personalised plates are permitted',
		( isset($_POST['license_plate']) ? $_POST['license_plate'] : '' )

// Show an error if license plate text field is not filled out when registering
