I'm a beginner in PHP and Silverstripe so I apologise if the question has a very simple answer.
I'm trying to get the last 8 items by date from a list of gigs and display them in reverse (ascending) order. here's my code:

//my php function
function Tour() {
      if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1) $_GET['start'] = 0;
      $SQL_start = (int)$_GET['start'];
      $doSet = DataObject::get(
        $callerClass = "GigDetail",
        $filter = "",
        $sort = "Date ASC",
        $join = "",
        $limit = "{$SQL_start},8"
      );

      return $doSet ? $doSet : false;
    }

//my ss file
<% control Tour %>
    <p>$Place - $Date.Nice - $Address <a href="$Link">more &raquo;</a></p>
<% end_control %>

This will show them in reverse order but from the bottom of the list. while I want to get the latest 8 gigs by date and display them in reverse order. Does it have anyting to do with $_GET['start'] ?

Thanks in advance

Wouldn't you want to use $sort = "Date DESC", to get highest to lowest rather than ASC?
