$showtable = true;
$errortag = false;
if (!empty($userlogin)) {
if (empty($username)){
 $errortag = true;
 $errormsg = $error_usernameempty;
}
if (empty($password)){
 $errortag = true;
 $errormsg = $error_passwordempty;
}
$customerid = $db->logincheck($username,$password);
if ($customerid==0) {
 $errortag = true;
 $errormsg = $error_wrongpassword;
}
if (!$errortag){
 session_register("CID");
 $_SESSION["CID"] = $customerid;
 $CID = $customerid;
                $_SESSION['username'] = $username;

I don't understand the question. It looks to me like you have set $_SESSION['username']=$username and have a form to receive the input. Just set $username=$_POST['username'] in the form handler somewhere before you set the session username.

There are two things. Since you have a POST form at the bottom of the page, why don't you just use a long "if (isset($_POST['submit'])) {" for the form handler? That javascript looks very shaky. This is the standard way to handle a single page form & form handler.

Second is, I can't understand any possible reason to use "session_register()". Take out all uses of it and similar deprecated functions, i.e. "session_is_registered()". And make sure you have register_globals set to "off" in your php.ini for your entire site.

Hi right i found out what code i want

lol, in the login.php code it has this

Code: Select all

$_SESSION["CID"] = $customerid;

which will show the users.

but what i want is to redirect the login.php page to my index.php page and then it will show this "Welcome Guest or Welcome Aaron1988" something like that mate.

and the code which should do that is

Code: Select all

$_SESSION["CID"] = $customerid;

but i dont know how to redirect the login.php page to the index.php and input the code into index.php

Hope that is clear if not let us know.

Thanks
Aaron
