如图的效果
调用标签：(链接自己定 {$MODULE[4][linkurl]} 为公司)
{php $sqareas=get_mainarea(0);}
{loop $sqareas $k $v}
<a href="{$MODULE[4][linkurl]}search.php?areaid={$v[areaid]}" target="_blank">{$v[areaname]}</a>
{php $smareas=get_mainarea($v['areaid']);}
{loop $smareas $i $t}
<a href="{$MODULE[4][linkurl]}search.php?areaid={$t[areaid]}" target="_blank">{$t[areaname]}</a>
{/loop}
{/loop}
