thinkphpdevelop

小的刚接触MVC开发模式，用thinkphp开发的时候，用户提交过来的表单，对表单的验证是放在c层还是在m层呀？

回复讨论(解决方案)

你先认真阅读一下开发手册

放在C里面。

看下手册

thinkphp 内置的在model验证

如果你觉得不方便，可以接收参数在C进行手动验证。

model层入库的时候进行验证
如果不入库的话自己在C 层做验证吧不是有个I函数吗？

封装在M层更好，入库前对必填字段和数据合法性都统一检查一遍
比如用户名密码必填且位数大于6，手机和邮箱格式等等
操作成功返回true，失败返回错误字符串，然后在C层根据情况$this->error()直接打印错误，还是ajax返回
M层的接口可以被C层多个页面调用

cm都可以.

M层，自动验证。

谢谢，M层函数的参数来源使用C层的，这样的话M层的方法可以重用，对于数据的验证还是在M层的好

Give an example of storing an array in a PHP session.Apr 27, 2025 am 12:20 AM

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AM

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

How can you use a database to store PHP session data?Apr 27, 2025 am 12:02 AM

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AM

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
