Basic MY_Model question. Need some help

[eluser]victorche[/eluser]
One last question... How can I optimise this:

Code:

public function all_records($table, $where = array(), $field = FALSE, $order = 'ASC')
{
  if (is_array($where) && count($where))
  {
   foreach ($where as $key => $value)
   {
    $this->db->where($key, $value);
   }
  }

  if ($field)
  {
   $this->db->order_by($field, $order);
  }

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

  return $query->result_array();
}

The problem is that I don't always have a where clause. And if I have an order_by clause, then I have to call this function like:

Code:

$posts = $this->model_something->all_records('posts', '', 'author');

Which is ugly and I want to optimise it
