第一步：

在include/global.fun.php中加入兩個函數

函數一：

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

函數二：

function select_search($name,$tb,$fid){global $db;$title="<select><option value= >所有</option>";$r = $db->get_one("SELECT option_value FROM {$db->pre}fields WHERE 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;}

第一個函數的意思是過濾空格回車

第二個函數是根據 name（自定義字段） tb（所屬模型） $fid（當前所選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)?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)}
