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}
