Question

用户/管理员可以根据需要登录和注册学生。点击完成后我们需要提供支付选项然后选择后我们需要为所有学生生成注册号码，所有学生必须在最后选择相同的支付选项。

我的问题是如何保存每个学生的表格值（包含近100个字段），直到他点击完成以及如何插入并生成所有这些学生的注册号

Answer 1

您可以使用JQUERY来编辑html，根据需要添加更多其他字段。对于每个新学生，请在字段名称中增加ID号。在一个表单上提交所有信息，然后解析结果。

Answer 2

对于管理部分，您可以尝试：

session_start(['username']);

if (isset($_SESSION['username']))
{

$user = $_SESSION['username'];
$connect = mysql_connect("localhost","root","");
mysql_select_db("login");

$POST = mysql_query("SELECT * FROM users WHERE username='$user'");
while ($row = mysql_fetch_assoc($POST))
{
    $admin = $row['account'];
}

if ($admin ==0)
die("You're not an admin <a href='member.php'>Main menu</a>");



}
else
            die("You must be logged in <a href='index.php'>Back</a>");
?>

用户表：

CREATE TABLE IF NOT EXISTS `users` (
  `userid` int(11) NOT NULL AUTO_INCREMENT,
  `firstname` varchar(25) NOT NULL,
  `surname` varchar(25) NOT NULL,
  `email` varchar(1024) NOT NULL,
  `password` varchar(30) NOT NULL,
  `username` varchar(25) NOT NULL,
  `account` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`userid`)
