Broken query:

	public function login(){
		extract($_POST);

		$qry = $this->conn->query("SELECT * from users where username = '$username' and password = md5('$password') ");
		if($qry->num_rows > 0){
			foreach($qry->fetch_array() as $k => $v){
				if(!is_numeric($k) && $k != 'password'){
					$this->settings->set_userdata($k,$v);
				}

			}

The fix, but not strong enough!

	public function login(){
		extract($_POST);

		$qry = $this->conn->query("SELECT * from users where username = ('$username') and password = md5('$password') ");
		if($qry->num_rows > 0){
			foreach($qry->fetch_array() as $k => $v){
				if(!is_numeric($k) && $k != 'password'){
					$this->settings->set_userdata($k,$v);
				}

			}
