Answer 1

After defining your custom field (that you did in your code mentioned above), add the code mentioned below to:

1. Process your field

2. Save it in the database as Order meta data

3. Display it in the 'Order details' in the Woocommerce->Orders section

Process your field:

add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {

if (!$_POST['billing']['billing_gls_name']) {
    wc_add_notice(__('Please tell us the Location Type that we are billing to.'), 'error');
}

}

Save Field in the DB as Order Meta Data:

add_action('woocommerce_checkout_update_order_meta','my_custom_checkout_field_update_order_meta');

function my_custom_checkout_field_update_order_meta($order_id) {

  if (!empty($_POST['billing']['billing_gls_name'])) {
     update_post_meta($order_id, 'Billing Gls Name', esc_attr($_POST['billing']['billing_gls_name_type']));
     }
 }

And finally display it in the Order details screen:

  add_action('woocommerce_admin_order_data_after_billing_address', 'my_custom_billing_fields_display_admin_order_meta', 10, 1);

  function my_custom_billing_fields_display_admin_order_meta($order) {
echo '
' . __('Billing Gls Name') . ':
 ' . get_post_meta($order->id, '_billing_gls_name', true) . '
';
}
