Je kunt geen enkele quotes gebruiken zonder ze te escapen als je die ook aan de buitenkant van je regel gebruikt zegmaar.

Probeer hem zo eens:

En doe even mysql_real_escape_string() om $username heen, is wat veiliger.

Maar dan klopt if(mysql_num_rows() == 1) toch niet meer?

Dan krijg je zoiets als dit , Warning: Wrong parameter count for mysql_num_rows() in C:Users****DesktopWebserverrootloggedin.php on line 13

Oja, moet je er even dit van maken:
