phpcms文章如何筛选分类
phpcms文章筛选分类的方法：
首先，用下面这些代码替换掉phpcms/libs/functions/extention.func.php的内容
<?php /** * extention.func.php 用户自定义函数库 * * @copyright (C) 2005-2010 PHPCMS * @license http://www.phpcms.cn/license/ * @lastmodify 2010-10-27 */ /** * 通过指定keyid形式显示所有联动菜单 * @param $keyid 菜单主id * @param $linkageid 联动菜单id,0调用顶级 * @param $modelid 模型id * @param $fieldname 字段名称 */ function show_linkage($keyid, $linkageid = 0, $modelid = '', $fieldname='zone') { $datas = $infos = $array = array(); $keyid = intval($keyid); $linkageid = intval($linkageid); //当前菜单id $field_value = intval($_GET[$fieldname]); $urlrule = structure_filters_url($fieldname,$array,1,$modelid); if($keyid == 0) return false; $datas = getcache($keyid,'linkage'); $infos = $datas['data']; foreach($infos as $k=>$v){ if($v['parentid']==$field_value){ $array[$k]['name'] = $v['name']; $array[$k]['value'] = $k; $array[$k]['url'] = str_replace('{'.$fieldname.'}',$k,$urlrule); $array[$k]['menu'] = $field_value == $k ?

然后，内容——模型管理——选择一个模型添加新字段，如图。

最后，在要调用产品筛选的栏目模板页添加标签 ，如下。
<span>性别：</span> {loop filters('xingbie',$modelid) $r} {$r[menu]} {/loop}
{php $sql = structure_filters_sql($modelid)} {php $urlrule = makeurlrule()} {pc:content action="lists" where="$sql" catid="$catid" num="10" order="id DESC" page="$page" urlrule="$urlrule"}
- {loop $data $r}
-
{str_cut($r[title],28)}
{/loop}
{$pages}
{/pc}
