phpcms实现联动筛选的教程目前还没有,下面CMS资源网就给大家分享一下phpcms如何实现列表页联动筛选,筛选效果截图如下:

话不多说,下面开始详细教程:


首先用下面代码替换掉phpcms/libs/functions/extention.func.php文件里面的代码:

如果大家不想复制代码,也可以直接下载下面的文件覆盖即可,下载地址如下:
http://pan.baidu.com/s/1o6ksvma

 

说明一下,这里用的是模型里的下拉框,模板里面的调用代码如下:


 

 <span>性别:</span>
{php $xingbie_rang = array('男|1','女|2','组合|3')}
{loop filters('xingbie',$modelid,$xingbie_rang) $r}
{$r[menu]}
{/loop}


{php $sql = structure_filters_sql($modelid)}
{php $urlrule = makeurlrule()}
{pc:content action="lists" catid="$catid" where="$sql" num="35" order="id DESC" page="$page" moreinfo="1" urlrule="$urlrule"}
{loop $data $r}
<dl>
<dt><a href="{$r[url]}" title="{$r[title]}" target="_blank"><img src="{$r[thumb]}" alt="{$r[title]}" width="130" height="200" /></a></dt>
<dd><h2><a href="{$r[url]}" title="{$r[title]}" target="_blank">{$r[title]}</a></h2></dd>
</dl>
{/loop}
{/pc}

 


上面的代码是以性别为例的,大家可以自己修改。

 

如果要实现伪静态,可以参考下面的伪静态规则:

 

rewrite ^/list-([0-9]+)-([0-9]+).html /index.php?m=content&c=index&a=lists&catid=$1&page=$2;
rewrite ^/list-([0-9]+)-(.*)-(.*)-(.*)-(.*)-([0-9]+).html /index.php?m=content&c=index&a=lists&catid=$1&diqu=$2&xingbie=$3&xingzuo=$4&zimu=$5&page=$6;
