$attach_info=wp_upload_bits($_FILES["file"]["name"], null, file_get_contents($_FILES["file"]["tmp_name"]));

$attach_id = wp_insert_attachment($data, $attach_info['file'], 0);


                $addon_id['media_id'] = $attach_id;
                $addon_id['media_url'] = wp_get_attachment_url( esc_attr( $attach_id ) );
                $cart_item_meta['wau_addon_ids'][] = $addon_id;
            }
