赢得的电影；t排序

大家都帮了点忙。

在我的电影页面上，我可以按4件事对电影进行排序，但一次只有1件

    ABC
Date Added
Imdb Ratings
Year

但我试着同时根据Year和Imdb Ratings两个因素对电影进行排序，但这行不通。

你能检查一下错误的原因吗

这是公共功能代码

 public function getRealMovies($lang=null, $p=null, $l=null, $sortby=null){
    $movies = array();
    if (($p) && ($l)){
        $start = ($p-1)*$l;
        $limit = " LIMIT $start,$l";
    } else {
        $limit = '';
    }
    if (!$sortby || $sortby=='abc'){
        $order = "ORDER BY title ASC";
    } elseif ($sortby=='date'){
        $order = "ORDER BY date_added DESC";
    } elseif ($sortby=='imdb_rating'){
        $order = "ORDER BY imdb_rating DESC";
    } elseif ($sortby=='year'){
        $order = "ORDER BY year DESC";
    } elseif ($sortby=='imdb_rating&year'){
        $order = "ORDER BY imdb_rating, year DESC";        
    }
    $e = mysql_query("SELECT * FROM movies WHERE id IN (SELECT movie_id FROM movie_embeds) $order $limit") or die(mysql_error());
    if (mysql_num_rows($e)>0){
        $ids = array();
        while($s = mysql_fetch_array($e)){
            $movies[$s['id']] = $this->formatMovieData($s, $lang);
            $ids[] = $s['id'];
        }
        if (count($ids)){
            $flags = $this->getFlags($ids);
            if (count($flags)){
                foreach($movies as $movie_id => $val){
                    if (array_key_exists($movie_id,$flags)){
                        $movies[$movie_id]['languages'] = $flags[$movie_id];
                    } else {
                        $movies[$movie_id]['languages'] = array();
                    }    
                }
            }
        }
    }
    return $movies;
}

这是重写角色

RewriteRule ^/?movies/('d+)$ index.php?menu=movies&p=$1&sortby=abc&lang=en [L]
RewriteRule ^/?movies/abc/('d+)$ index.php?menu=movies&p=$1&sortby=abc&lang=en [L]
RewriteRule ^/?movies/date/('d+)$ index.php?menu=movies&p=$1&sortby=date&lang=en [L]

有人能帮忙吗？

谢谢：）
