  • It looks like you don't handle for the case where `$username` is invalid. You simultaneously check for a result and the password verification. Split these up (check for an actual result). – Mike May 29 '18 at 13:20
  • ok i solv it ^^ if(count($results) > 0 && $hashpass == $results['user_password']){ – PeanutStick May 29 '18 at 13:44
