You not setting the array properly. but I don't think you need the [ ] brackets either in the array itself.

You would do something like

Code:

$my_array = array();

Code:

$this->db->set($my_array);

Below is an example of a poll I did

Code:

#controller function
function submit()
{
    if($this->input->post('opt_id') == '0')
    {
    $this->errors->poll_no_selection();
    }
    else
    {
    $this->poll_model->submit_vote($this->input->post('userid'), $this->input->post('poll_id'), $this->input->post('opt_id'));
    redirect('/poll/iframe/' . $this->input->post('poll_id'));
    }
}

Code:

#model function
function submit_vote($userid, $pollid, $optid)
{
$array = array(
    'poll_id' => $pollid,
    'opt_id' => $optid,
    'userid' => $userid
);
$this->db->set($array);
$this->db->insert('poll_votes', $this->db->escape($_POST));
