开发简述：使用phpcms V9系统，修改源文件5个，创建模型：楼盘、出售、出租、中介、小区，增加联动菜单：楼盘，增加用户组：房产中介。

实现功能：

游客发布信息、会员申请中介、楼盘全方位展示、报名团购、看房功能，发布信息时可根据登陆后的会员资料自动填好联系信息，中介有自己的店铺，可给中介留言，联动筛选搜索、排序，房源对比功能。

联动筛选搜索功能的实现方法及代码：

要修改的文件就是list.html模板

核心代码：

<?php

$theurl = APP_PATH."index.php?m=content&c=index&a=lists&catid=$catid";

$where = "status=99";

$orderby = "";

foreach ($_GET as $field => $r) {

if($r) {

if(!in_array($field,array('m','c','a','page'))){

if(strrpos($field,'_')){

$arr=explode("-",$r);

$field = str_replace('_','',$field);

$where .= " AND $field >= '$arr[0]' AND $field <= '$arr[1]'";

}else if($field == 'title'){

$where .= " AND $field LIKE "."'%".$r."%'";

}else if($field == 'orderby'){

$orderby = str_replace('_',' ',$r);

}else{

$where .= " AND $field='$r'";

}

}

}

}

//if($where)$where = substr($where,5);

if(!$orderby)$orderby = "id desc";

?>

用这段代码来构造查询条件和排序方式，有了这段代码之后，要把list.htm获得列表的pc语句改造成这样

原来的

{pc:content action="lists" catid="$catid" num="25" order="id DESC" page="$page"}

改造后的

{pc:content action="lists" where="$where" catid="$catid" num="25" order="$orderby" page="$page"}

使用的时候就比较麻烦了

<p><span>状态：</span><span><a href='{url_par("price_=$_GET[price_]&hstatus=& typeid=$_GET[typeid]&address=$_GET[address]",$theurl)}'>全部</a& amp; gt;</span>

<span {if $_GET[hstatus] == 1}class='shaixuan'{/if}><a href='{url_par("price_=$_GET[price_]&hstatus=1& typeid=$_GET[typeid]&address=$_GET[address]",$theurl)}'>新盘</a& amp; gt;</span>

</p>

<p><span>类型：</span><span><a href="{url_par("price_=$_GET[price_]&hstatus=$_GET[hstatus]& typeid=&address=$_GET[address]",$theurl)}">全部</a></span& amp; gt;

{/loop}

{/pc}</p>

<p><span>地区：</span>

没办法，要想联动，就得每次都传递出所有需要联动的参数，所以url的参数部分就很多，容易晕掉～

获取搜索结果的代码是

共返回 {php echo count($data);} 个结果

放在

{pc:content action="lists" where="$where" catid="$catid" num="25" order="$orderby" page="$page"}

下面

loop

的上面

共返回 {php echo count($data);} 个结果

排序的参数也很麻烦

<a href='{url_par("price_=$_GET[price_]&area_=$_GET[area_]& shi=$_GET[shi]&typeid=$_GET[typeid]&address=$_GET[address]& orderby=area_desc",$theurl)}'>面积</a>

基本就这样了，希望有人能看懂

搜索表单也可以直接用在这里

给个例子

<form name="myform1" method="get" action="">

<input type="hidden" name="m" value="content">

<input type="hidden" name="c" value="index">

<input type="hidden" name="a" value="lists">

<span><select name="catid">

<option value="6">出售</option>

<option value="12">求购</option>

</select></span>

<span><select name="area_">

<option value="">面积不限</option>

<option value="0-50">小于50</option>

<option value="50-80">50到80</option>

<option value="80-120">80到120</option>

<option value="120-200">120到200</option>

<option value="200-10000">大于200</option>

</select></span>

<span><select name="shi">

<option value="">所有户型</option>

<option value="1">1室</option>

<option value="2">2室</option>

<option value="3">3室</option>

</select></span>

<span><input name="title" type="text" class="text4" style="width:60px;" /></span>

<span><input type="submit" value="" class="text3" /></span></form>
