destoon在分类下调用当前栏目中发布过商品的公司

IT人

打开/include/global.func.php

在最后边加上以下代码：

function get_com($catid){

global $db;

$sql="select * from ".$db->pre."category where catid=".$catid."";//调用当前栏目所有子分类

$result=mysql_query($sql);

$catids='';

while($count=mysql_fetch_array($result))

{

  $catids.=$count['arrchildid'];

}

$row=array();

$sql2="select a.username,a.userid,a.company, COUNT(b.itemid) AS com_num from ".$db->pre."member as a,".$db->pre."mall as b where a.username=b.username and b.catid in ($catids) GROUP BY b.username HAVINg com_num > 0 ";

$result2=mysql_query($sql2);

while($count2=mysql_fetch_array($result2)){

  $row[]=$count2;

}

return $row;

}

代码内容不解释

再打开你要用的模板，模板地方参考以下代码，自行修改

{php $cominfo=get_com($c[catid]);}

         {loop $cominfo $co $val}

         <dd><a rel="nofollow" title="{$val[company]}" target="_blank" href="{userurl($val[username])}"><span>{$val[company]}</span></a></dd>

         {/loop}



$c[catid]是上一层loop遍历出来的．把数据取出来了，遍历跟据自己情况写loop吧．
