[eluser]meer[/eluser]
ok i got it
the problem is that, you have not get the anname data from any where , so try this code to get the anname from your table

first u modify your model please

$this->db->select('anname');
$this->db->where('email',$this->input->post(email));
$this->db->where('pwd',$this->input->post(pwd));
$query = $this->db->get("your_tbl_name");
if($query->num_rows()>0)
{
return $query->result();
}

in your controller

if($query) // if the user's credentials validated...
{
$aname=$query->anname;
$data = array(
'admin_name' => $anname,
'is_logged_in' => true
);
$this->load->library('session');
$this->session->set_userdata($data);
$this->load->view('logged_in_area');
}

i hope this will help you
