dedecms 添加自定义标签显示非dede表数据

需求：调用一个商城系统里面的产品数据到dedecms文章页，希望对需要类似需求的人有所帮助

功能实现：为了不用垮数据库查询，dedecms安装到商城系统数据库里面

下面是实现的代码(请根据自己的环境进行修改)

原文:dedecms 添加自定义标签显示非dede表数据

include/taglib/hongyungoods.lib.php

<?php /**  * @author http://www.heui.org/  */ if(!defined('DEDEINC')) exit('Request Error!');   functionlib_hongyungoods(&$ctag, &$refObj) {     global$dsql, $envs, $cfg_cmsurl;       //属性处理     $attlist="row|6,titlelen|0,tid|0";     FillAttsDefault($ctag->CAttribute->Items,$attlist);     extract($ctag->CAttribute->Items, EXTR_SKIP);       //只在指定栏目显示     if($tid>0 && $tid!= $envs['typeid']) return'';       if( !$dsql->IsTable("sl_products") ) return'没安装鸿运产品模块';       $innertext= $ctag->GetInnerText();     //@todo hongyungoods.htm     if(trim($innertext)=='') $innertext= GetSysTemplets("hongyungoods.htm");       //@todo 智能条件     $where= 1;     $limit= 5;       $ctp= newDedeTagParse();     $ctp->SetNameSpace('field', '[', ']');     $ret= '';     $query= "SELECT p.`Name` AS title,  CONCAT('http://www.hongyun2000.com/', ps.`AcStr`, '-view-', p.`ID`, '.html') AS url,  CONCAT('http://www.hongyun2000.com/uploadfile/s/', p.`Images`) AS img  FROM `sl_products` AS p  LEFT JOIN `sl_products_sort` AS ps ON p.`SID` = ps.`ID`  WHERE " . $where . "ORDER BY RAND() LIMIT " . $limit;       $dsql->Execute('me',$query);   while($rs= $dsql->GetArray('me'))   {       $rs['title'] = 0 == $titlelen?$rs['title']:cn_substr($rs['title'], $titlelen);         $ctp->LoadSource($innertext);       foreach($ctp->CTags as$tagid=>$ctag) {             if(!empty($rs[strtolower($ctag->GetName())])) {                 $ctp->Assign($tagid,$rs[$ctag->GetName()]);             }           }           $ret.= $ctp->GetResult();   }     return$ret; }   ?>

调用页面使用：

{dede:hongyungoods} <dd>     <spanclass="tlink"><ahref="[field:url/]"><imgsrc="[field:img/]"alt="[field:title/]"/></a>     <ahref="[field:url/]"target="_blank">[field:title/]</a></span> </dd> {/dede:hongyungoods}
