The second question is more than I have time to answer, but setting an identifier, which could be the correct location for the redirect, when a user subscribes and then retrieving the identifier at login is probably easiest... Here's an example using number rather than an exact location:
// Mysql_num_row is counting table row
// $count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 rowif($loggedin=mysql_fetch_array($result)){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
if($loggedin['location']==1) {
header("location:login_success1.php");
}
elseif($loggedin['location']==2) {
header("location:login_success2.php");
}
elseif($loggedin['location']==3) {
header("location:login_success3.php");
}
}
else {
echo "Wrong Username or Password";
}
