求你了，我真的需要帮助。下面的代码是在我的网站上将搜索查询保存为标记的代码，但它将标题替换为“-”，请问有什么方法可以使标记标题名称保持搜索状态？。

function addsometags() {

//Don\'t do anything if we\'ve already got 20 tags
$posttags = get_the_tags();
$count=0;
if ($posttags) {
foreach($posttags as $tag) {
$count++;
if ($count==20) break;
}
}


if ($count<20) {
        global $wpdb;

        $engines[\'google.\'] = \'q=\';
        $engines[\'altavista.com\'] = \'q=\';
        $engines[\'search.msn.\'] = \'q=\';
        $engines[\'yahoo.\'] = \'p=\';
        $engines[\'bing.\'] = \'q=\';
        $engines[\'yandex.\'] = \'text=\';

        $referer = $_SERVER[\'HTTP_REFERER\'];
        $blogtarget = $_SERVER["REQUEST_URI"];
        $ref_arr = parse_url("$referer");
        $ref_host = $ref_arr[\'host\'];

        foreach($engines as $host => $skey){
            if (strpos($ref_host, $host) !== false){
                $res_query = urldecode($ref_arr[\'query\']);
                if (preg_match("/{$engines[$host]}(.*?)&/si",$res_query."&",$matches)){
                    $query = trim($matches[1]);
                    $target = str_replace("\'","\'\'",str_replace(";","",sanitize_title_with_dashes($query)));
                    global $post;
                    $thePostID = $post->ID;
                    wp_add_post_tags($thePostID, $target);
            }
        }
    }
 }
}


add_action(\'wp_footer\', \'addsometags\');
