我整整一周都在努力让这个工作，但到目前为止还没有任何运气。我正在建立一个员工系统，作为我的第一个项目，我真的可以使用你的帮助。
我有一个ref_employees带有 x 个字段的表的数据库。
我设法获得了一些资源来编辑记录，并认为我的问题已经解决了。尽管来源帮助我编辑了记录，但客户端需要通过上传和存储功能获得更多功能。我已经相应地编辑了代码，但现在有 2 个问题。
1）我必须将上传表单与编辑表单分开添加，因为当单击编辑更新时，即使在数据库中添加回显上传字段中的当前值后，它也会清除数据库中的上传字段。
2）上传显示它正在上传，但没有保存在指定的目录中。权限设置为 777，相关字段中的文件名不会被捕获到数据库中。我认为这是因为上传功能在一个单独的页面中，而不是与上传表单在同一页面上。
我需要它来上传文件，将其存储在目录中，最后将文件名放在警告字段所在的数据库中，但需要在正在编辑的记录（员工）下捕获它。
我是新手，感谢所有帮助。
