我正在使用 post 变量，并且我正在尝试使用来自 url 的 get 变量来登录用户。
这是过程：
用户获得自己的 url，即 kayden.domain.com
当他们创建自己的帐户时，他们拥有自己的用户名并通过
当他们来到 kayden.domain.com 时，他们会使用这些凭据。
为了验证，我正在检查帖子变量（用户名和密码）并尝试使用 $_GET['user_group'] 进行验证。
该脚本在我只使用 post 变量时有效，但在 GET 时它不起作用。下面是代码：
PHP：
$SUBDOMAIN = mysql_real_escape_string($_GET['user_group']);
// Process the POST variables
$username = $_SESSION["user_name"];
//$password = $_POST["password"];
// Set up the session variables
$_SESSION["user_name"] = $username;
$secret = $info['password'];
//Checks if there is a login cookie
if(isset($_COOKIE['ID_my_site']))
//if there is, it logs you in and directes you to the members page
{
$username = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
$check = mysql_query("SELECT user_name, password FROM accounts WHERE user_name = '$username' and user_group='$user_group'")or die(mysql_error());
while($info = mysql_fetch_array( $check ))
{
if (@ $info['password'] != $pass)
{
}
else
{
header("Location: members.php");
}
}
}
//if the login form is submitted
if (isset($_POST['submit'])) { // if form has been submitted
// makes sure they filled it in
if(!$_POST['user_name'] | !$_POST['password']) {
die('You did not fill in a required field.');
}
// checks it against the database
if (!get_magic_quotes_gpc()) {
$_POST['user_name'] = addslashes($_POST['user_name']);
$_GET['user_group'] = addslashes($_GET['user_group']);
}
$check = mysql_query("SELECT user_name,password FROM accounts WHERE user_name = '".$_POST['user_name']."' and user_group='".$_GET['user_group']."'")or die(mysql_error());
//Gives error if user dosen't exist
$check2 = mysql_num_rows($check);
if ($check2 == 0) {
die('That user does not exist in our database. <a href=add.php>Click Here to Register</a>');
}
while($info = mysql_fetch_array( $check ))
{
$_POST['password'] = md5($_POST['password']);
$_POST['password'] = $_POST['password'];
//gives error if the password is wrong
if (@ $_POST['password'] != $info['password']) {
die('Incorrect password, please try again');
}
else
{
// if login is ok then we add a cookie
$_POST['user_name'] = stripslashes($_POST['user_name']);
$hour = time() + 3600;
setcookie(ID_my_site, $_POST['user_name'], $hour);
setcookie(Key_my_site, $_POST['password'], $hour);
//then redirect them to the members area
header("Location: members.php");
}
}
}
else
{
// if they are not logged in
