我整整一周都在试着让这个太过分了，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，我可以真正使用你的帮助。
我有一个数据库，其中包含一个名为ref_employees的表，其中包含x个字段。
我设法抓住了一些来源编辑记录并认为我的问题已经解决了。虽然源帮助我编辑记录，但客户端需要通过上传和存储功能来实现更多功能。我已相应地编辑了代码但现在有2个问题。
1）我必须将上传表单分别添加到编辑表单中，因为当单击编辑的更新时，即使添加了回显db中上载字段中的当前值，它也会清除数据库中的上载字段。 / p>
2）上传显示正在上传但未保存在指定目录中。权限设置为777，文件名未在相关字段的数据库中捕获。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。
我是新手，所有的帮助都表示赞赏。
