删除不适用于子页面的自定义POST类型插件

我希望我的自定义帖子类型products不要使用slug，例如：domain。com/产品名称。下面的代码很好地解决了这一问题，但它无法处理子页面，例如：域。com/产品名称/产品名称功能，it 404s。

我最初尝试将自定义帖子类型的重写段标为“/”，虽然这对自定义帖子类型很好，但它杀死了普通页面（404）。因此，如果解决方案是使用“/”，然后修复普通页面，也可以。

// Post Type

function base_types() {

    $labels = array(
        \'name\'               => \'Products & Features\',
        \'singular_name\'      => \'Product\',
        \'add_new\'            => \'Add New\',
        \'add_new_item\'       => \'Add New Product / Feature\',
        \'edit_item\'          => \'Edit Product\',
        \'new_item\'           => \'New Product\',
        \'all_items\'          => \'All\',
        \'view_item\'          => \'View Product / Feature\',
        \'search_items\'       => \'Search Product / Feature\',
        \'not_found\'          => \'None found\',
        \'not_found_in_trash\' => \'None found in Trash\',
        \'parent_item_colon\'  => \'\',
        \'menu_name\'          => \'Products / Features\'
    );

    $args = array(
        \'labels\'             => $labels,
        \'public\'             => true,
        \'publicly_queryable\' => true,
        \'show_ui\'            => true,
        \'show_in_menu\'       => true,
        \'query_var\'          => true,
        \'rewrite\'            => array( \'slug\' => \'product\', \'with_front\' => false ),
        \'capability_type\'    => \'page\',
        \'has_archive\'        => false,
        \'hierarchical\'       => true,
        \'menu_position\'      => 10,
        \'with_front\'         => false,
        \'menu_icon\'          => \'dashicons-chart-bar\',
        \'supports\'           => array( \'title\', \'editor\', \'author\', \'page-attributes\' )
    );

    register_post_type( \'product\', $args );

}

add_action( \'init\', \'base_types\' );


// Rewrites

function remove_slug( $post_link, $post, $leavename ) {

    if ( \'product\' != $post->post_type || \'publish\' != $post->post_status ) {
        return $post_link;
    }
    if( $post->post_parent ) {

        $parent = get_post($post->post_parent);
        $post_link = str_replace( \'/\' . $post->post_type . \'/\' . $parent->post_name . \'/\', \'/\' . $parent->post_name . \'/\', $post_link );

    }

    else {

        $post_link = str_replace( \'/\' . $post->post_type . \'/\', \'/\', $post_link );
    }
    return $post_link;
}

add_filter( \'post_type_link\', \'remove_slug\', 10, 3 );


function parse_request( $query ) {

    if ( ! $query->is_main_query() || 2 != count( $query->query ) || ! isset( $query->query[\'page\'] ) ) {
        return;
    }

    if ( ! empty( $query->query[\'name\'] ) ) {
        $query->set( \'post_type\', array( \'post\', \'product\', \'page\' ) );
    }
}

add_action( \'pre_get_posts\', \'parse_request\' );

第一级页面按预期工作。子页面获得了正确的永久链接，但它们是404。

有人能帮忙或指出正确的方向吗？非常感谢。
