Sorting orders in admin

[colinr]

Hi There,

I'd like to be able to sort the display or orders in the admin area by a field other than customer id. Is there a simple way to achieve this?

The source at /admin/orders.php suggests a value can be passed in using 'list_order' as a variable in the url:

// Sort Listing
          switch ($_GET['list_order']) {
              case "id-asc":
              $disp_order = "c.customers_id";
              break;
              case "firstname":
              $disp_order = "c.customers_firstname";
              break;
              case "firstname-desc":
              $disp_order = "c.customers_firstname DESC";
              break;
              case "lastname":
              $disp_order = "c.customers_lastname, c.customers_firstname";
              break;
              case "lastname-desc":
              $disp_order = "c.customers_lastname DESC, c.customers_firstname";
              break;
              case "company":
              $disp_order = "a.entry_company";
              break;
              case "company-desc":
              $disp_order = "a.entry_company DESC";
              break;
              default:
              $disp_order = "c.customers_id DESC";
          }

...but when I try it nothing changes.

Any help or advise would be much appreciated.
