Re-login to session...

Anon

Hello !

I got a system where the user can login with username/password. The code-snipped is attached. It works fine, every page got $user and $pass.

The problem: In the system, a user could login. Okay. Then another user should be able to login without closing the browser ! I tried session_unset(), session_destroy, but after calling Check the 2nd-time, the first user is stilll logged on.

Ideas ?

To login, I call:
function Check($name, $password)
{ global $pass, $user;
// ..check, is $name and $password fits
...
// start Session
session_unset();
session_start();
$user = $name;
session_register("user");
$pass = md5($password);
session_register("pass");
}

To get $user, $password on every page, I use:
session_start();
print "User:".$user."<P>\n";
print "Pass:".$pass."<P>\n";

i dont know if I understand you correctly, but I think you first need to 'initialize' the old session before you can destroy it.
so you should do :

session_start(); //this gets he old session
session_destroy(); //destroy the old one
session_start(); // start the new one

i've just started using sessions myself, so i'm not sure, but i think this should do it...

I did that, too, and it didn't work either.

I found out that I have to call start_session() OUTSIDE the class (my function check was a class-member). I think, it has something to do with global variables, but I don't know, which variables has to be global for start_session().

Hi all,

I have tried

session_start()
session_unregister($var)
session_destroy()
session_unset()

echo $var;

The $var is still available when this page loads but when I reload the same page using the browser's reload button the $var is lost ..... can anybody tell me what is going on

Thanks

Anon

it is not session_unregister($var);

eg:if $var = "danny";

then do : session_unregister("var");

else do
unset($var) and not session_unset($var);

Hi Danny,

My mistake ....... I put the $ sign in this board by mistake... :-8

Actually in the code I did put session_unregister("var");
but then it still would print the contents of $var on immediately the next line.

Strange huh ... whats more strange is that only when I reload that page by the browsers reload butn the session gets unregistered

While I still try to find answers to that question users on my site have a feature where they have to login only once ...lol
