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)
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}
