我对PHP很陌生，无法弄清楚为什么我得到这个错误。 $ _POST不应该从表单中获取该值吗？感谢您的阅读。

这意味着您的players表不包含email列。您需要将此列添加到您的表中才能使用此脚本。

因此，在你的代码不正确的部分是

$newPlayer = @mysql_query("INSERT INTO players(username, password, registered, callname, email) 
          VALUES('$uname', '$pass', '$date', '$_POST[callname]', '$_POST[email]')") or die("Error: ".mysql_error());

在我的情况下，该列确实存在，但我忘记将非整数变量括在引号！ ;） – Leo 2016-04-07 15:24:00

在您的播放表中添加email场。
有可能是你拼错了email在播放器中。

$sql = "INSERT INTO user_registration (u_name,s_father,s_schoolname,s_rollno,s_class) 
VALUES ($name,$father,$school,$rollno,$class)";
