这里我使用了两种形式，
1.signup.php
2.signup2.php

使用从表单1到表单2检索数据的会话输入数据，输入的值不会插入到数据库中。

您的最终插入查询是否在final.php中？我认为你在signup2.php中的行为将带你进入dreams.php，而不是final.php 改变这个

<form method = "post" action = "dreams.php">

请修改查询以适合您的表结构

$\u POST['ucourse']

应该是一个数组，您不能连接它，您必须先将其内爆。您已更改但未插入数据库php是否会引发任何错误？您是否每次都运行

创建表学生

？或者你只是为了让我们理解表的结构而展示它吗？当我创建表单时，我将与createtable studentsis一起提交所有final.php代码？因为我看不到任何要插入数据库的查询。让我看看您所有的final.php代码您的final.php代码不包含任何sql插入查询dude。所以这些值不会被插入到DB中。见我编辑的帖子

<form method = "post" action = "final.php">

mysqli_query($con, "INSERT INTO your_table VALUES($_SESSION['ucourse'], $_SESSION['uclass'],$_SESSION['ucontact'],$_SESSION['uaddress']");
