destoon设置自定义搜索的方法

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)?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)}
