第一步:

在include/global.fun.php中加入两个函数

函数一:

function loseSpace($pcon){
$pcon = preg_replace("/ /","",$pcon);
$pcon = preg_replace("/ /","",$pcon);
$pcon = preg_replace("/ /","",$pcon);
$pcon = preg_replace("/\r\n/","",$pcon);
$pcon = str_replace(chr(13),"",$pcon);
$pcon = str_replace(chr(10),"",$pcon);
$pcon = str_replace(chr(9),"",$pcon);
return $pcon;
}

函数二:

function select_search($name,$tb,$fid){
    global $db;
    $title="<select name=".$name."><option value= >所有</option>";
    $r = $db->get_one("SELECT option_value FROM {$db->pre}fields WHERE name='$name' and tb='$tb'");
    $option_value=loseSpace($r["option_value"]);
    $ps = split("\*", $option_value);
    #var_dump($matchs);
    foreach ($ps as $s){
    //以*分割1|可用*=> 1, 可用
     if(!$s){
    continue;
     }
     list($num,$word) = split("\|", $s);
     $result[$num] = $word;
    }     
    foreach($result as $n => $v)
    {
    if ($n==$fid){
     $title .=" <option value=".$n." selected>".$v."</option>";
    }
    else{
     $title .=" <option value=".$n.">".$v."</option>";
    }
    }
    $title .="</select>";
    return $title;
}

第一个函数的意思是过滤空格回车

第二个函数是根据 name(自定义字段) tb(所属模型) $fid(当前所选ID)生成下拉列表。

第二步:

在module/sell/search.inc.php中的$day = isset($day) ? intval($day) : 0;下插入

$chengse = isset($chengse)&#63;intval($chengse):0;

在if($vip) $condition .= " AND vip>0";下加入

if($chengse) $condition .= " AND chengse=$chengse";

然后在模板文件中使用:

{select_search(chengse,sell,$chengse)}
