phpcms v9教程联动搜索在房地产网站开发中的应用

2022-12-01 13:08:20

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>
<span {if $_get[hstatus] == 2}class='shaixuan'{/if}><a href='{url_par("price_=$_get[price_]&hstatus=2& typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>在售</a& amp; gt;</span>
<span {if $_get[hstatus] == 3}class='shaixuan'{/if}><a href='{url_par("price_=$_get[price_]&hstatus=3& typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>尾盘</a& amp; gt;</span>
<span {if $_get[hstatus] == 4}class='shaixuan'{/if}><a href='{url_par("price_=$_get[price_]&hstatus=4& typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>售完</a& amp; gt;</span></p>
<p><span>均价：</span><span><a href='{url_par("price_=&hstatus=$_get[hstatus]& typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>全部</a& amp; gt;</span>
<span {if $_get[price_] == '0-4000'}class='shaixuan'{/if}><a href='{url_par("price_=0-4000&hstatus=$_get[hstatus]& typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>4000以下& amp; lt;/a></span>
<span {if $_get[price_] == '4000-5000'}class='shaixuan'{/if}><a href='{url_par("price_=4000-5000&typeid=$_get[typeid]&hstatus=$_get[hstatus]&address=$_get[address]",$theurl)}'>4000-5000</a></span>
<span {if $_get[price_] == '5000-6000'}class='shaixuan'{/if}><a href='{url_par("price_=5000-6000&hstatus=$_get[hstatus]&typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>5000-6000</a></span>
<span {if $_get[price_] == '6000-7000'}class='shaixuan'{/if}><a href='{url_par("price_=6000-7000&hstatus=$_get[hstatus]&typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>6000-7000</a></span>
<span {if $_get[price_] == '7000-8000'}class='shaixuan'{/if}><a href='{url_par("price_=7000-8000&hstatus=$_get[hstatus]&typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>7000-8000</a></span>
<span {if $_get[price_] == '8000-9000'}class='shaixuan'{/if}><a href='{url_par("price_=8000-9000&hstatus=$_get[hstatus]&typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>8000-9000</a></span>
<span {if $_get[price_] == '9000-10000'}class='shaixuan'{/if}><a href='{url_par("price_=9000-10000&hstatus=$_get[hstatus]&typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>9000-10000</a></span>
<span {if $_get[price_] == '10000-100000'}class='shaixuan'{/if}><a href='{url_par("price_=10000-100000&hstatus=$_get[hstatus]& typeid=$_get[typeid]&address=$_get[address]",$theurl)}'>10000以上& amp; lt;/a></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;
{pc:get sql="select * from `v9house_type` where `module`='content'"}
{loop $data $key $val}
<span {if $_get[typeid] == $val[typeid]}class='shaixuan'{/if}><a href="{url_par("price_=$_get[price_]&hstatus=$_get[hstatus]&typeid=$val[typeid]&address=$_get[address]",$theurl)}">{$val[name]}</a></span>
{/loop}
{/pc}</p>
<p><span>地区：</span>
<span><a href="{url_par("price_=$_get[price_]&hstatus=$_get[hstatus]& typeid=$_get[typeid]&address=",$theurl)}">全部</a></span& amp; gt;
{pc:get sql="select linkageid,name from `v9house_linkage` where parentid=(select linkageid from `v9house_linkage` where name='淄博市')"}
{loop $data $key $val}
<span {if $_get[address] == $val[linkageid]}class='shaixuan'{/if}> <a href="{url_par("price_=$_get[price_]&hstatus=$_get[hstatus]&typeid=$_get[typeid]&address=$val[linkageid]",$theurl)}">{$val[name]}</a></span>
{/loop}
{/pc}</p>

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

</select></span>
