您可以很容易地使CPT具有“无栓”永久链接：

register_post_type( \'service\', [
    \'hierarchical\' => true,
    \'public\'       => true,
    // Other args, no need for "rewrite"
]);

// Change service to top-level permalink.
add_permastruct( \'service\', \'%service%\', [
    \'with_front\' => false,
    \'paged\'      => false,
    \'feed\'       => false,
]);

// Remove all default service rewrite rules.
add_filter( \'service_rewrite_rules\', \'__return_empty_array\' );

。。。应该将其包装在函数中并连接到init. 然后要“抓住”这些帖子类型，我们需要一点pre_get_posts 魔术：

add_action( \'pre_get_posts\', function ( $wp_query ) {
    if (
        $wp_query->is_main_query() &&
        $wp_query->is_singular() &&
        $wp_query->get( \'pagename\' )
    ) {
        if ( ! $post_type = $wp_query->get( \'post_type\' ) )
            $post_type = [];
        elseif ( ! is_array( $post_type ) )
            $post_type = [ $post_type ];

        $wp_query->set( \'post_type\', array_merge( $post_type, [
            \'page\',
            \'service\',
        ]));
    }
});

然后确保刷新重写规则（只需在管理中加载设置>永久链接）。
