Code:
$data[] = array(

'username' => $this->input->post('username'),
'log' => TRUE,
);

This is the issue
you can do this:
Code:
$data['username'] =  $this->input->post('username');
$data['log'] = TRUE;

then u can access it like this :
Code:
$name = $this->session->userdata('username');
$log = $this->session->userdata('log');

or u can do this :
Code:
$data['user_info']=array(

'username' => $this->input->post('username'),
'log' => TRUE,
);
$user_info = $this->session->userdata('user_info');
$name = $user_info['username'];


and don't forget that session will be available on the next request(I mean you need to refresh page then display it,you can not display sessions right after seting it)
