PHP 万能查询代码

小项目中存在很多省市区加模糊查询：

以下THINKPHP + JS 构成万能查询代码；方便快捷。

前端：

<select id="s_province" name="pro"></select>&nbsp;&nbsp;
<select id="s_city" name="city" ></select>&nbsp;&nbsp;
<select id="s_county" name="area"></select>&nbsp;&nbsp;
<input type="text" style=" 200px" name = "search" id ="search" value ="{$search}" placeholder="地址综合会员名称搜索">
<input type="button" value ="搜索" onclick = "search('/index.php?s=/Shendou/Member/mList')">
<script class="resources library" src="__STATIC__/area.js" type="text/javascript"></script>
<script type="text/javascript">_init_area();</script>

<script>
$pro = "<?php echo $pro ?>";
$city = "<?php echo $city ?>";
$area = "<?php echo $area ?>";
if($pro != ""){
update($pro,$city,$area);
}
</script>

效果：

JS 代码

function search(basePath){
    var pro = $("#s_province").val();
    var city = $("#s_city").val();
    var area = $("#s_county").val();
    //obj 代表当前选哪个select框框
    var parm = "";
    var type = "";
    if(area != '市、县级市'){
        type = "area";
        parm = area;
    }else if(city != '地级市'){
        type = "city";
        parm = city;
    }else if(pro != '省份'){
        type = "pro";
        parm = pro;
    }
    var search =$("#search").val();

    window.location.href = basePath+"/type/"+type+"/parm/"+parm+"/search/"+search+"/pro/"+pro+"/city/"+city+"/area/"+area+".html";

}

bathPath: 主要是构造提交路径；

后端代码：

$wherestr = " AND 1 = 1 ";

$type = $_REQUEST['type'];
$parm = $_REQUEST['parm'];
$search = $_REQUEST['search'];

if($parm){
$wherestr .= "AND `$type` = '$parm'";
}

if($search){
$wherestr .= "AND `shopname` like '%$search%'";
}

$type = $_REQUEST['type'];
$parm = $_REQUEST['parm'];
$search = $_REQUEST['search'];

if($parm){
$wherestr .= "AND `$type` = '$parm'";
}

if($search){
$wherestr .= "AND `shopname` like '%$search%'"; 
}
维护查询后选中

  $pro = $_REQUEST['pro'];
  $city = $_REQUEST['city'];
  $area = $_REQUEST['area'];
  $this->assign('pro',$pro);
  $this->assign('city',$city);
  $this->assign('area',$area);
  $this->assign('search',$search);
