Session not working in some pages

[eluser]CodeIgniteMe[/eluser]
which part of your codes did you put this?

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 check your session values by echoing

Code:

$this->session->all_userdata();

I think you probably had some errors in your code. note your array, the last comma after your last element
