When m logging out from my page, it has to be redirected & in this process im loosing my session variables. Is that any process to keep the variables constant after the redirection .. After the page redirection m getting undefined index error.. Any help .. ?? Thank you in advance
You're destroying whole session on logout page. While you just need to unset the relevant session key.
Something like,
session_start();
unset($_SESSION['login_user']); //session_destroy();
header('Location:'.$_SERVER['HTTP_REFERER']);
exit;
instead of using session_destroy();
you should use unset($_SESSION['login_user']);
It will change the value of the variable in the session to null and you will not lose your variable . session_destroy()
destroys the session completely and then you have no way to access that variable.
You can check the difference between them using var_dump
eg:- session_destroy(); var_dump($_SESSION['login_user']);
session_destroy(); var_dump($_SESSION['login_user']);
and
unset($_SESSION['login_user']); var_dump($_SESSION['login_user']);
AND in your code
if (!isset($_SESSION)){
}
you should not keep it blank. I think you forgot to include the following code inside this block
