Answer 1

Don’t put spaces in your header("Location:.

else {
    //Login failed
    header("Location: login.php?msg=invalid%20name%20or%20password");
    exit();
}

EDIT: The %20s are actually spaces. Look at the PHP function urlencode() if you want more info. The code above is equivalent to this:

else {
    //Login failed
    header("Location: login.php?msg=" . urlencode("invalid name or password"));
    exit();
}
