hi this is my first time to try sessions of CI and im in trouble LOL
here's my controller code

Code:
public function login()

  {

    $username = $_POST['username'];

    $password = $_POST['passwd'];

    $data['username'] = $this->session->set_userdata('username',$username);

    $this->site_model->login($username,$password);

    $this->load->view('member_view',$data);

  }

model

Code:
public function login($username,$password)

    {

        $this->db->where('username',$username);

        $this->db->where('passwd',$password);

        $result = $this->db->get('user');

        return $result;

    }

view

Code:
&lt;?php

    if(isset($_SESSION['username'])){

      echo "you are logged in as .". $_SESSION['username'];

    }else{

      echo "you aren't logged in";

    }

?&gt;

when i try to log-in with a correct data, I'm just getting the
"you aren't logged in"

2 things...

1- are you loading the session library?

2- I think

Code:
isset($_SESSION['username']

should be

Code:
isset($this->session->userdata('username'))

and then

Code:
echo "you are logged in as .". $_SESSION['username'];

should be

Code:
echo "you are logged in as .". $this->session->userdata('username');

ok i tried what you said, now am getting this error

Code:
Fatal error: Can't use method return value in write context in C:\xampp\htdocs\myapp\application\views\member_view.php on line 4

where line 4 is the

Code:
if(isset($this->session->userdata('username'))){

(btw the session class is autoloaded from the config)

Sorry about that, it should be

Code:
&lt;?php

   $username = $this->session->userdata('username');

    if(isset($username)){

      echo "you are logged in as .". $username;

    }else{

      echo "you aren't logged in";

    }

?&gt;

but I suggest you to take a look at this video tutorial from nettuts to get some good practices because I think your code have some security issues like setting the cookie data before calling the login model....
