Array
( [0] => Array ( [idp] => 1 [fistnav] => 电脑办公 [Thirdnav] => )
[1] => Array ( [idp] => 2 [fistnav] => 家用电器 [Thirdnav] =>
Array ( [0] => Array ( [seid] => 1 [idp] => 2 [navtow] => 空调) [1] => Array ( [seid] => 2 [idp] => 2 [navtow] => 平板电视 )
[2] => Array ( [seid] => 3 [idp] => 2 [navtow] => 冰箱 ) ) )
[2] => Array ( [idp] => 3 [fistnav] => 手机数码 [Thirdnav] => )
)

这是数组。

<div class="pnavot">
<ul>
<volist name="pnav" id="noone">
<li>{$noone['fistnav']}
<ul>
<volist name="noone['thirdnav']" id="th">
<li>{$th['navtow']}</li>
</volist>
</ul>
</li>
</volist>
</ul>
</div>
第一个循环没问题，但第二个循环不显示，问题在哪里？
