Login.php Does not report bad logins

[mattotone]

Login.php and admin_model do not show errors on incorrect login or lockout after incorrect activations.

Fixes bellow.

LOGIN CONTROLLER

public function index()
{
/*
Error List:
0 - No Error
1 - Too Many Login Attempts
2 - Bad Credentials
*/
$data["error"] = 0;
if ($this->input->post())
{

		if (!$this->session->userdata("loginattempts")) {
			$this->session->set_userdata("loginattempts", 1);
		}
		$loginattempts = $this->session->userdata("loginattempts");		
		$postData = $this->input->post();
	
		if ($loginattempts > 4) {  //To Many Attempts
			$data["error"] = 1;
			echo"e1";
			$this->load->view('login', $data);
		} else {
			$auth = $this->Admin_model->adminLogin($postData);
			if ($auth == 0) {
				echo"s1";
				redirect(base_url(), "auto");
			} else {
				echo"e2";
				$data["error"] = 2;
				$this->session->set_userdata("loginattempts", $loginattempts + 1);
				$this->load->view('login', $data);
			}			
		} 
	} else {
		$this->load->view('login', $data);
	}
	
}

###ADMIN_MODLE
public function adminLogin($postData) {
if (!isset($postData["username"])) { return 2; }
if (!isset($postData["password"])) { return 2; }
$salt = $this->generateSalt();
$username = $this->db->escape(strip_tags($postData["username"]));
$password = $this->db->escape(strip_tags(md5($salt.$postData["password"])));
$sql = "SELECT * FROM admin WHERE username = ".$username." AND password = ".$password;
$query = $this->db->query($sql);
if ($query->num_rows() > 0) {
$q = $query->row();
$this->session->set_userdata("username",$q->username);
$this->session->set_userdata("verification_key",$q->verification_key);
$this->session->set_userdata("admin_id", $q->id);
$this->session->set_userdata("loggedin",1);
$ip = $this->getUserIP();
$sql2 = "UPDATE admin SET last_signin = NOW(), ip = ".$this->db->escape($ip)." WHERE id = ".$q->id;
$this->db->query($sql2);
return 0;
} else {
return 2;
}
}
