这里的问题是，当我想提交表单时，它将返回其原始状态（空表单）。表单中有两个部分，用户必须输入输入并上传文件。
这是表格..

我尝试评论文件上传过程并继续进行输入过程..但它仍然无需做任何事情就返回。我希望它可以显示一些错误，所以我可以解决。当它返回空时我也感到空虚。
有人能帮助我吗？我真的不知道如何继续。

您正在使用if(isset($_POST['submit'])，而这正在寻找一个按钮named“提交”，您可以在这里找到：
<input type="submit" value="Submit the form" id="submit" align="center">
应为：
<input type="submit" name="submit" value="Submit the form" id="submit" align="center">

不能工作。如果我理解你的代码是正确的，你通过$ _POST将数据发送到student_newSubmission.php。然后你通过“标题”找到你的旧页面，但你不发送$ _POST。您必须将数据发送保存到student_newSubmission并将其发送回另一页。每个脚本后都会删除$ _POST，您无法使用它，因此永久保存信息。你必须使用$ _COOKIE或$ _SESSION。
