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：

image

2.流程状态部分数据：

image

3.期望达到效果如下：

image

这里就需要用到几个部分的技巧结合

一般的循环嵌套使用
<volist name="list" id="vo">
    <volist name="vo['sub']" id="sub">
        {$sub.name}
    </volist>
</volist>

其中第二个volist的name属性，也可以写作name="vo.sub"

IF判断使用

常用的判断中，不允许使用<,>,=之类的符号，改为：

标签 含义
eq或者equal 等于
neq或者notequal 不等于
gt 大于
egt 大于等于
lt 小于
elt 小于等于
heq 恒等于
nheq 不恒等于 
1. <eq name="name" value="value">value</eq>

比较标签中的变量可以支持对象的属性或者数组，甚至可以是系统变量，例如： 当vo对象的属性（或者数组，或者自动判断）等于5就输出

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>

参考php

        $param['id'] = $id;
        $order = M('reorder')->where($param)->find();

        $orderStatus = M('reorderstatus')->where($where)->find();
        $orderStatus['status'] = explode('|',$orderStatus['status']);

        $param_process['isfinish'] = 'true';
        $status1 = M('reorderprocess')->where($param_process)->order('posttime')->select();
        //根据当前订单状态，分割orderStatus
        $param_process['isfinish'] = 'false';

       //$this->ajaxJSON($status2);
        //判断附加说明，是否含分隔符

            if($key > $least){
                array_push($status3,$value);
            }
        }
        //查找最新的流程附加信息
        $param_newest['orderid'] = $order['orderid'];
        $process_newest = M('reorderprocess')->where($param_newest)->order('posttime desc')->find();

        $counts = array();
        array_push($counts,0);
        array_push($counts,count($status1));
        array_push($counts,count($status1)+count($status2));
        $this->assign('order',$order);
        $this->assign('immiprogram',$immiprogram);
