ThinkPHP实现二级循环读取的方法,thinkphp实现读取

本文实例讲述了ThinkPHP实现二级循环读取的方法。分享给大家供大家参考。具体实现方法如下:

复制代码 代码如下:


$Category = D('Category')->where('category_pid=0')->findAll();
//dump($Category); 
if(!empty($Category)){ //判断一级是否为空
foreach($Category as $key=>$value){   //循环读取
$pid =  $value['category_id'];//字段赋值
$Category[$key]['child'] = D('Category')->where("category_pid =$pid")->select();
//echo D('Category')->getLastSql(); //打印sql语句的写法
}
}
//dump($Category);
$this->assign('Category',$Category);//映射值

希望本文所述对大家的ThinkPHP框架程序设计有所帮助。

THINKPHP中怎进行循环插入多条数据

你这数组写的也太那个了吧,一般谁都不会把数据写成这样的。我们会这样写:
$data = array( 0 => array( 'id'=>1, 'cate_id'=>1, 'coo_name'=>111 ), 1 => array( 'id'=>2, 'cate_id'=>2, 'coo_name'=>222 ));当然你这个数组也可以循环插入的:先把第一个id转换为数组,然后用foreach循环插入

 

foreach双重循环怎在ThinkPHP模板中输出

ThinkPHP模板用法:

{$vo.id}
{$vo.name}

在php页面得到这个变量后$jgbh,$this->display('index');这是页面的输出,
在html页面里写代码就行。

{$vo.ip}
{$vo.khname}

ThinkPHP是一个开源的框架,你可以先在官网上下载个使用手册,看看里面的例子,才能更好的学习它和熟悉它的用法。
希望能帮助到你
