This is because you haven't quoted the array subscript -- PHP thinks you're
trying to refer to a constant called login, but on not finding that assumes
that you meant the string 'login' instead. To suppress this notice, supply
the subscript correctly as a string:
if ($_GET['login'] == 'forgot')

This means that there was no login= parameter on the URL that called this
script. If this is a permissible condition, you need to allow for it in
your code. One way is simply to suppress the error message with the @
operator:
if (@$_GET['login'] == 'forgot')
Another is to do more explicit checking:
if (isset($_GET['login']) && $_GET['login'] == 'forgot')
Which you use is really down to personal preference.
Cheers!
