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
文件内容如下:
- 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'没安装产品模块';
-
- $innertext= $ctag->GetInnerText();
-
- if(trim($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.genban.org/', ps.`AcStr`, '-view-', p.`ID`, '.html') AS url,
-
- CONCAT('http://www.genban.org/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;
-
- }
-
-
- ?>
