Answer 1

Function redirect() doesn't save anything. You can try save $data to session by writing $this->session->set_userdata('some_name', $data);

Then you can call them with $this->session->userdata('some_name');

Note that $data can be object or array.

Assume that $data is array, then in dashboard you can use something like this:

$data = $this->session->userdata('some_name');
echo 'Username: '.$data['username'].'<br />';
echo 'Family: '.$data['family'];

...... so on ........

Answer 2

As per your question, you are validating the user login details and creating session for them.

Then store user information in session.

set session library auto-load in config/autoload.php. Then create session as below.

$this->session->set_userdata(
     array(
             "username"=>$username,
             "user_id" => $user_id,
             "family"  => $family    
            )    
);

In Dashboard:

You can access session with it's name:

echo $this->session->userdata("username");
