Ok so I finally solved it. You should really have a model (it helps a lot)

In your model do something like

Model

class poll_model extends CI_MODEL {

 function __construct() {
   $this-load->database(); 
 }

 function get_poll {
   $this->db->query("SELECT * FROM table");
   $row = $query->row();

   $obj = array(
    'id' => $row->id
  );
   return $obj;
 }
}

Now if you have more than an id say name of poll # you can add in array. Now in your controller do

class Poll extends CI_Controller {

public function __construct()
   {
        parent::__construct();
        $this->load->database();
        $this->load->helper('form');
        $this->load->model('poll_model');
   }

public function index()
{
    $data["a"] = $this->poll_model->get_poll();
    $this->load->view('poll_view',$data);
}

And finally in VIEW put

This is a big help. I figured it out by testing and it works for me.
