CodeIgniter - return only one row?

Question

At the moment if I am doing a query on the database that should only return one row, using:

...query stuff...
$query = $this->db->get();
$ret = $query-         


        

Answer 1

class receipt_model extends CI_Model {

   public function index(){

      $this->db->select('*');

      $this->db->from('donor_details');

      $this->db->order_by('donor_id','desc');

      $query=$this->db->get();

      $row=$query->row();

      return $row;
 }

}
