Answer 1

In Model

public function book_update(....)
{
    $data = array(
        ...
    );

    $this->db->where('id', $id);

    if (!$this->db->update('mytable', $data))
        return false;
    else
        return true;

}

In Controller

$result = $this->book_model->book_update(array('book_id' => $this->input->post('book_id')), $data);
echo json_encode(array("status" => $result));

In Html

You will get TRUE of FALSE based on update success/fail.
