destoon循环嵌套查询

想了两天都没理清思路，今天下午经过经理点播终于搞出来了，循环调用嵌套还可以这样用。只要两个表内由相关字段，都可以进行关联查询。

<!--{php $tags=tag("moduleid=4&condition=level=1&length=28&pagesize=6&order=userid desc&template=null");}--> 

<div class="">
<ul class="clearfix comp">
{loop $tags $i $t}
<li class="comp_li">
<div class="clearfix comp_logo">
<a href="{$t[linkurl]}" target="_blank"><img class="" alt="{$t[title]}" src="{$t[thumb]}"/></a>
<a href="{$t[linkurl]}" title="{$t[title]}" target="_blank">{$t[company]}</a><br/>
<span>{$t[business]}</span>
</div>

<div class="mall_sell clearfix">
<!--{php $mall=tag("moduleid=16&condition=username='".$t[username]."'&pagesize=3&template=null");}-->


{loop $mall $v}
<a href="{$v[linkurl]}" target="_blank">
<img class="comp_img" alt="{$t[alt]}" src="{$v[thumb]}" />

<p>{$DT[money_sign]}{$v[price]}{if $v[unit]}<span class="mall_unit">/{$v[unit]}</span>{/if}</p>
{/loop}
</a> 

</div>
<div class="clearfix comp_address">
<p class="">联系电话：{$t[telephone]}</p>
<a href="{$t[linkurl]}">进入商家店铺</a>
</div>
</li>
{/loop}
</ul>
</div>
