版本为：5。51

栏目外循环：

select top 50 id,foldername from ks_class where tj=1 and topflag=1 and

channelid=1 order by folderorder

[loop=50]
<div style="background:#DDE3FB;height:25px;line-height:25px"><strong><a

href="{$Field(id,GetInfoUrl,100,1)}">{$Field(foldername,Text,0,...,0,)}

</a></strong></div>
<div class="n">
 <ul>
{SQL_栏目内循环({$Field(id,GetInfoUrl,100,2)})}
 </ul>
</div>
[/loop]

======================================================

栏目内循环：

select top 50 id,foldername from ks_class where tn='{$Param(0)}' order by

folderorder

[loop=20]
<li><a href="{$Field(id,GetInfoUrl,100,1)}">{$Field(foldername,Text,0,...,0,)}</a></li>
[/loop]

=======================================================

效果：

是因为5.51不支持，SQL标签嵌套 吗 ？
