not sure, but might be an issue:
in updateList function you have
*$orderid = 0;*
$add="catID ".strval($catid)." orderid".strval($orderid)."\n"
;
but yet in save_items_order.php you have:
*$i = 1;* # will represent the actual order (starting at 1).
$query = "UPDATE hln_stations SET order_col = $i WHERE id = $itemid";
in the function you start at 0 in the update file you start at 1.
as a follow up -- on the link you posted as your reference they have order
starting at 1:
public function updateList($orderArray) {
*$orderid = 1;*
foreach($orderArray as $catid) {
$catid = (int) $catid;
$sql = "UPDATE categories SET orderid={$orderid} WHERE
catid={$catid}";
$recordSet = mysql_query($sql,$this->conn);
$orderid++;
}
}
