[eluser]CodeIgniteMe[/eluser]
what browser are you using?
what is displayed after you put this?

Code:

$this->session->all_userdata();

how do you access your saved sessions?

Code:

$data = array(
        'Title' => $this->input->post(TITLE),
        'Price' => 45,
        'Keywords' => $this->input->post(IMAGE_KEYWORDS),
                                    
        );
        $this->session->set_userdata('imagedata', $data);
        redirect(SOME_WHERE);

you can access them like this

Code:

$this->session->userdata('item');
