无法将课程上传到 Laravel 项目中的数据库

问题描述 投票：0回答：1

我正在进行 Laravel 项目。特征：

Laravel Framework 10.48.12
、
Composer version 2.7.7 2024-06-10 22:11:12
、
PHP 8.3.7 (cli) (built: May  8 2024 08:56:56) (ZTS Visual C++ 2019 x64) Copyright (c) The PHP Group Zend Engine v4.3.7, Copyright (c) Zend Technologies
、
Intervention Image (^2.7)
。 我无法将课程上传到数据库，也没有显示错误消息。按提交后，它似乎只是刷新到 /add/course 页面，该页面应该重定向到 /all/course 页面。 这是代码

add_course.blade.php

我需要帮助。预先感谢您。

我尝试检查名称是否与数据库中的名称匹配，我还添加了一些错误消息，但同样的事情。

我希望将课程上传到数据库，按提交后，它似乎只是刷新到 /add/course 页面，该页面应该重定向到 /all/course 页面。但没有显示错误信息。

这是由于 

php.ini
文件中 
upload_max_filesize
和 
post_max_size
的当前值造成的。它们分别限于 
2M
和 
8M
。我将它们的值分别增加到 
10M
和 
40M
，它起作用了
