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