好的，因为您将这些附加值保存为自定义字段（请参见下面的代码）：

function save_points(){
        global $post;
        update_post_meta($post->ID, "category", $_POST["category"]);
        update_post_meta($post->ID, "brand", $_POST["brand"]);
        update_post_meta($post->ID, "features", $_POST["features"]);
        update_post_meta($post->ID, "holds", $_POST["holds"]);
        update_post_meta($post->ID, "extra", $_POST["extra"]);
}
