You have $_SESSION['user_type'] = $user_type but what is $user_type?
You did not initialize it anywhere, so nothing will be stored in $_SESSION['user_type'].
You have to first fetch the result from the database,
and assign the value of the result to $user_type variable, before you can store it.
$row = mysqli_fetch_assoc($result);
$user_type = $row['user_type'];
