40分求ThinkPHP循环嵌套打印出父类与子类的列表
大家好,我近段时间在学习thinkPHP框架,我想在模板页面实现循环打印出一个数据列表,格式是:先是父类类别名称,再接着打印出对应的子类列表,再接着打印另外一个父类名称,再打印该父类的对应的子类,以此类推。。。我是用表格排版,格式如:
类别名 简介
父类名称1 ......
子类名称1 .....
子类名称2 .....
子类名称3 .....
父类名称2 ......
子类名称1 .....
子类名称2 .....
子类名称3 .....
请问用volist该怎样实现,或者有没有更好的方法,请指教,感激不尽!!

你不看他的手册吗?
Volist标签
Volist标签主要用于在模板中循环输出数据集或者多维数组。
通常模型的select和findall方法返回的结果是一个二维数组,可以直接使用volist标签进行输出。
在Action中首先对模版赋值:
$User = M('User');
$list = $User->select();
$this->assign('list',$list);
在模版定义如下,循环输出用户的编号和姓名:
{$vo.id}
{$vo.name}
Volist标签的name属性表示模板赋值的变量名称,因此不可随意在模板文件中改变。id表示当前的循环变量,可以随意指定,但确保不要和name属性冲突,例如:
{$data.id}
{$data.name}
支持输出部分数据,例如输出其中的第5~15条记录
{$vo.name}

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.
