In order for your new fields that you have added to Helpful’s feedback form to be recognized by Helpful, you must address them with this filter. Otherwise Helpful will not process your own fields.

How you can add your own fields to the feedback form, you can find in another article.

 * @param array $fields
 * @return array
add_filter('helpful_feedback_fields', function (array $fields) {
    $fields[] = 'custom_field';
    return $fields;
