我有演员和流派分类法。

add_action(\'init\',\'ap_url_redirect_rules\');
add_filter(\'query_vars\', \'ap_register_query_vars\');
function ap_url_redirect_rules(){
    add_rewrite_rule(\'([^/]+)?$\', \'index.php?actor=$matches[1]\', \'top\'); // .com/brad-pitt
    add_rewrite_rule(\'([^/]+)/([^/]+)?$\', \'index.php?actor=$matches[1]&sort=$matches[2]\', \'top\'); // .com/brad-pitt/popular or new, etc.
    add_rewrite_rule(\'genre/([^&]+)?$\', \'index.php?genre=$matches[1]\', \'top\'); // .com/genre/comedy
    add_rewrite_rule(\'genre/([^/]+)/([^/]+)?$\', \'index.php?genre=$matches[1]&sort=$matches[2]\', \'top\'); // .com/genre/popular or new, etc.
    flush_rewrite_rules();
}
function ap_register_query_vars($query_vars){
    $query_vars[]=\'sort\';
    return $query_vars;
}

我有这个密码。演员重写规则有效，但体裁和单个帖子（帖子链接）无效(404 Page Not Found). 我怎么了？
