在WordPress中为父级和子级自定义类别设置永久链接

Question

如果该帖子重复，对此表示抱歉。我找不到这种情况。 我的主要post_type = post具有默认的永久链接。参见下图。

而且，我有一个自定义帖子类型，我称之为[post_type = fsgallery]。 另外，我创建了一个自定义分类法，名为gallery_category。此类别具有父类别。例如/ movies / drama，/ movies / horror等。

我创建了一些重写规则，但是我不知道如何声明像这样的永久链接http：//：//xxx.com/workbench-gallery/movies/drama（domain / workbench-gallery / parent_category / child_category）

我安装了许多自定义的Manage permalink插件，但没有找到任何对子类别的父类别有用的插件。

这是我的代码，用于重写自定义永久链接。     

    function wpa_show_permalinks($post_link, $post)
    {
        if (is_object($post) && $post->post_type == 'fsgallery') {
            $terms = wp_get_object_terms($post->ID, 'fsgallery_category');
            if ($terms) {
                $primary_cat_id = get_post_meta($post->ID,     '_yoast_wpseo_primary_fsgallery_category', true);
                foreach ($terms as $term_key => $term_object) {
                    if ($term_object->term_id == $primary_cat_id) {
                    // Return this as the primary term
                    return str_replace('%fsgallery_category%', $terms[$term_key]->slug, $post_link);
                    }
                }
            } else {
                return str_replace('%fsgallery_category%', '', $post_link);


        }
    }
    return $post_link;
}
add_filter('post_type_link', 'wpa_show_permalinks', 1, 2);
</pre>


I found my parent and child categories, but how to set both of them to the URL?.
