ThinkPHP关于模板的一些嵌套、IF判断使用

> ##### 前言，现在有一组数据（涉及到3个数据表，order订单表，order_process办理流程表，process_status流程描述表），根据当前订单，展示相应信息

1.办理流程部分数据：

2.流程状态部分数据：

3.期望达到效果如下：

<volist name="list" id="vo">
<volist name="vo['sub']" id="sub">
{$sub.name}
</volist>
</volist>

1. <eq name="name" value="value">value</eq>

2 .<eq name="vo.name" value="5">
{$vo.name}
</eq>

3.  <!-- 附加说明 判断数组大小-->
<if condition="count($vo['additional']) gt 1">
附加说明：
<else /> other Framework
</if>

4.  <!-- 附加说明 判断数组大小-->
<if condition="strlen($vo['additional']['0']) gt 1">
附加说明：
<else /> other Framework
</if>

public function orderDetail($id, $userId) {
$param['id'] = $id;
$order = M('reorder')->where($param)->find();
//0.更新订单被查看的信息：查看人、查看时间
$watch['userId'] = $userId;
$watch['posttime2'] = time();
M('reorder')->where($param)->save($watch);

//获取当前项目的默认办理流程
$where['projectid'] = $order['projectid'];

$param_process['orderid'] = $order['orderid'];
$param_process['isfinish'] = 'true';

//根据当前订单状态，分割orderStatus
$param_process['isfinish'] = 'false';
