打开/include/taglib/tag.lib.php文件
找到
<span style="font-size:14px;" deep="13">if($getall==0 && isset($refObj->Fields['tags']) && !empty($refObj->Fields['aid']))
{
        $dsql->SetQuery("Select tid From `dede_taglist` where aid = '{$refObj->Fields['aid']}' ");
        $dsql->Execute();
        $ids = '';
        while($row = $dsql->GetArray())
  {
          $ids .= ( $ids=='' ? $row['tid'] : ','.$row['tid'] );
        }
        if($ids != '')
        {
                $addsql = " where id in($ids) ";
        }
        if($addsql=='') return '';
}</span>
在它下面加入
<span style="font-size:14px;">else if($getall==2)
{
$addsql = " where typeid='{$refObj->Fields['typeid']}' ";
}
</span>
前端调用
<span style="font-size:14px;">{dede:tag sort='hot' getall='2'}
<a href='[field:link/]'>[field:tag /]</a>
{/dede:tag}</span>
