[$_SESSION Variable checking does not work...]

add session_start to the beginning of the logout function and try it again.

 

Thank you so mouch, see, i knew i had done something stupid!

(Added start session)

[$_SESSION Variable checking does not work...]

it returns true because the Login() function sets $_SESSION["loggedin"] to true when called.

 

I know that , but when i call the logout function and then call the check login, it still returns true.

[$_SESSION Variable checking does not work...]

<?php
function Login()
{
    session_start();
$_SESSION["loggedin"] = true;
echo "You are logged in!";
    header("Location: ../L_index.php"); //Aka Logged in Index.
}

function Logout()
{
$_SESSION["loggedin"] = false;
    session_destroy();
}

function checklogin()
{
    session_start();
    if ($_SESSION["loggedin"] == true)
    {
        return true;
    }
    else
    {
        return false;
    }
}
?>

 

This is just a tiny bit of my code, there is security holes, but as you see, there is 3 functions:

Login

Logout

Checklogin

 

But when i use the Login function, everything is fine, but if i then use the checklogin, then it always returns true(it returns true after i used the logout function), why?
