如何篩選分類phpcms文章?相信很多沒有經(jīng)驗的人對此束手無策,為此本文總結(jié)了問題出現(xiàn)的原因和解決方法,通過這篇文章希望你能解決這個問題。
phpcms文章篩選分類的方法:
首先,用下面這些代碼替換掉phpcms/libs/functions/extention.func.php的內(nèi)容
<?php /** * extention.func.php 用戶自定義函數(shù)庫 * * @copyright (C) 2005-2010 PHPCMS * @license http://www.phpcms.cn/license/ * @lastmodify 2010-10-27 */ /** * 通過指定keyid形式顯示所有聯(lián)動菜單 * @param $keyid 菜單主id * @param $linkageid 聯(lián)動菜單id,0調(diào)用頂級 * @param $modelid 模型id * @param $fieldname 字段名稱 */ function show_linkage($keyid, $linkageid = 0, $modelid = '', $fieldname='zone') { $datas = $infos = $array = array(); $keyid = intval($keyid); $linkageid = intval($linkageid); //當(dāng)前菜單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,內(nèi)容——模型管理——選擇一個模型添加新字段,如圖。
最后,在要調(diào)用產(chǎn)品篩選的欄目模板頁添加標(biāo)簽 ,如下。
<span>性別:</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}
