Hi!, i am trying about aditional fields on functions.php

add_filter( ‘woocommerce_checkout_fields’ , ‘woocommerce_checkout_field_editor’ );
// Our hooked in function – $fields is passed via the filter!
function woocommerce_checkout_field_editor( $fields ) {
$fields[‘billing’][‘billing_field_invoice_email’] = array(
‘label’ => __(‘Invoice Email’, ‘woocommerce’),
‘placeholder’ => _x(‘Invoice Email’, ‘placeholder’, ‘woocommerce’),
‘required’ => false
);
return $fields;
}
