cannot set user data in session codeigniter

Question

please look at this.

The code below is from my model class (using datamapper orm)

 function login()
    {

        $u = new User();


        $u->where('username', $this->username)->get();


        $this->salt = $u->salt;

        $this->validate()->get();


        if (empty($this->id))
        {
            // Login failed, so set a custom error message
            $this->error_message('login', 'Username or password invalid');

            return FALSE;
        }
        else
        {
            // Login succeeded
            $data = array
            (
                'username' => $u->username,
                'usergroup' => $u->usergroup->get(),
                'is_logged_in' => true

            );
            $this->session->set_userdata($data);


            return TRUE;
        }
    }

when i do this i get

**Fatal error: Call to a member function set_userdata() on a non-object**

but when i do this instead

$data = array
            (
                'username' => $u->username,
                'usergroup' => $u->usergroup->get(),
                'is_logged_in' => true
            );
            $obj=& get_instance();
            $obj->session->set_userdata($data);

It works.

Please what is the right way to get this working ?

Thanks in advance.

Did you load the session library first? $this->load->library('session') — Vikk

Are you doing this from a library? In that case the $this will not contain the CI instance, see the section "Utilizing CodeIgniter Resources within Your Library" at codeigniter.com/user_guide/general/creating_libraries.html — danneth

sorry for my late response. I am doing all of this from a model (datamapper orm model) — Moyo Falaye

your model did not extends CI_Model after that you have to add constructor to your model add this code to yours

function __construct()
    {
        parent::__construct();
        $this->load->library('session');
    }

Well, you didn't provide enough information. The first code looks fine, provided that:

You actually load the session class before calling it (you also need to create an encryption key in your configs). $this->load->library('session'); $this->session->set_userdata($data);
The above code, or your code, is inside a controller, a model or a view. $this relates to the CI's superclass, in particular to an instance of the Session class, so if you're calling that inside a helper (collection of functions), or inside a library (where you need to create a CI instance first), it won't work.

@mojotaker I still don't see where you load the session class...is it autoloaded?
