session problem

[eluser]ciGR[/eluser]
For the last question you should save an array to your session, for example

Code:

$user = Array(
    'username'=>'ciGR',
    'password'=>'1234test'
    );        
$this->session->set_userdata('user',$user);

and for get the data in array you can use the

Code:

$user = $this->session->userdata('user');
print_r($user);//check the result

now you have again the array.
