sessions

[Pino]

Ok i've got a big deadline to meet and i didnt wnat to run into problems like this

Ok all my code has been fine so far for my UserCP they log in and i assign a string to a session variable name 'myid' then each page checks the string corrosponds to what it should be, eg here is my log in script

Session_Start();

if ($username==$dbuser and $mpassword==$dbpassword)
{
        $_SESSION['myid'] = "ymn2prymn2pr";
        header('Location: /admin.html');
        exit();
}
else
{
        session_destroy();
        unset($_SESSION);
        header('Location: /badpw.html');
        exit();

} 

I've missed off the db connection bit and removed the url but it all works fine because it goes to the admin page.

in the admin page there is this code

session_start();

if ($_SESSION['myid'] != "ymn2prymn2pr")
{
        session_destroy();
        unset($_SESSION);
        header('Location: /hckattempt.html');
        exit();  
} 

as you see it checks to make sure the varible should be the string. now then the thing is when i try and echo the session variable 'myid' its empty.

Is this a server error? Or is my login code incorrect?
