Thinkphp中数据按分类嵌套循环实现方法,thinkphp嵌套

本文实例讲述了Thinkphp中数据按分类嵌套循环实现方法。分享给大家供大家参考。具体实现方法如下:

做thinkphp时要用到循环里面嵌套循环的,并第二个循环是和外面的有关联的。
thinkphp官网给出的文档为:

复制代码 代码如下:

 
     
        {$sub.name} 
   
 

我这里要用的表为:分类表(表1),数据表(表2)
要实现的效果为:

 
   
   
表1_1> 
 
   
   
表1_2> 

其实原理也是先查出分类表(表1),再把表1和表2相关联查询,最后以二维数组的方式输出

后台代码如下:

复制代码 代码如下:

$m=M('表1'); 
$m1=M('表2'); 
 
$parent=$m->select(); 
foreach($parent as $n=> $val){ 
    $parent[$n]['voo']=$m1->where('表2里和表1相关联的字段='.$val['表1id'].'')->select(); 

$this->assign('list',$parent); 
$this->display();


前台输出显示:

复制代码 代码如下:

 
   

  • {$vo.id}
  •  
         
          
  • {$sub.title}
  •  
       
     


    效果如下图所示:

    希望本文所述对大家的ThinkPHP程序设计有所帮助。
