回复讨论(解决方案)

这是显示结果，显示2秒后就又跳转回注册页面了，哪里出错了？

$xuehao...这几个变量是哪里来的？

那也是$_POST['xuehao'] 呀

那也是$_POST['xuehao'] 呀什么意思？

错误提示：$xuehao未定义！！！

register.php
extract($_POST); //加上这句
if ($xuehao=="" ||$name=="" || $class=="" ||$password=="" ||$password1=="" ||$telephone=="")

是不是可以这样理解呢？
$heihao 定义的变量。。
$_GET['xuehao'] 才是从另一个页面传递过来的呢。。

我也是菜鸟，刚接触

register.php
extract($_POST); //加上这句
if ($xuehao=="" ||$name=="" || $class=="" ||$password=="" ||$password1=="" ||$telephone=="") 感谢，问题解决了！
