<?php

function wooc_extra_register_fields() {

       ?>



       <p class="form-row form-row-first">

       <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>
