Did you start the session? And your indenting has no relation to how the code is actually being executed, `$_SESSION["username"]` will always be unset. — jeroen, Aug 17 '17 at 07:19

It seem some bad logic in code, try

if (isset($_POST["name"]) && isset($_POST["password"])) {
    $_SESSION["username"]=$_POST["name"];        
}

if(isset($_POST["logout"])) {
    unset($_SESSION["username"]);
}
