我折腾了好一阵子终于弄明白咋回事了,
首页 article:list 标签在首页不能用
数据模板变量name="lists"

下面的是我用volist标签的例子

<volist name="lists" id="vo" offset="1" length='10'>
<if condition="$vo['category_id'] lt 4 "> value1

<else /> value2

</if>


<div class="">
<h3><a href="{:U('Article/detail?id='.$vo['id'])}">{$vo.title}</a></h3>
</div>
<div>
<span class="author">{$vo.uid|get_username}</span>
<span>于 {$vo.create_time|date='Y-m-d H:i',###}</span> 发表在
<span><a href="{:U('Article/lists?category='.get_category_name($vo['category_id']))}">{$vo.category_id|get_category_title}</a></span>
<span>阅读({$vo.view})</span>  
</div>
<hr/>

</volist>
