You get the error because $submit is not defined. You need to use
$_POST['submit'] (and probably $_POST['username'] and
$_POST['password'] as well).

Read this:

<http://www.php.net/manual/en/langua....predefined.php>

And pay special attention to the notes about register_globals.

It should also be noted that Notices are not Errors as such. Your
script will normally execute fine with Notices but for improved security
and performance you should try to avoid them.
