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 ?

'<em>'.$v[0].'</em>' : '<a href='.$option[$k]['url'].'>'.$v[0].'</a>' ;}$all['name'] = '全部';$all['url'] = structure_filters_url($field,array($field=>''),2,$modelid);$all['menu'] = $field_value == '' ?

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"}<ul class="photo-list picbig">{loop $data $r}<li><div class="img-wrap"><a href="{$r[url]}"><img src="{thumb($r[thumb],150,112)}" width="150" height="112" alt="{$r[title]}"/></a></div><span style="color:{$r[style]}">{str_cut($r[title],28)}</span></li>{/loop}</ul><div id="pages" class="text-c">{$pages}</div>{/pc}
