Changing best sellers block to recently sold

[tout2004]

Hi, Ive fixed most of my problems in adapting my theme using this forum but there is one which i am stuck on.

 

With the best sellers page they are displayed by highest price first (as is the preference for the rest of my store) but I would like it to be displayed by order date so it can be turned in to a recently sold page.

 

Im using 1.4.5.1, am I on the right track in editing classes/productsale.php???

 

public static function getBestSales($id_lang, $pageNumber = 0, $nbProducts = 10, $orderBy=NULL, $orderWay=NULL)
{
 if ($pageNumber < 0) $pageNumber = 0;
 if ($nbProducts < 1) $nbProducts = 10;
 if (empty($orderBy) || $orderBy == 'position') $orderBy = 'sales';
 if (empty($orderWay)) $orderWay = 'DESC';

 

I tried

if (empty($orderBy) || $orderBy == 'position') $orderBy = 'invoice_date';

but that didnt do anything.

 

(I could find order date to put there so thought invoice date would do just as well???)

 

So I need to edit the dispaly order to date sold - most recent first and remove the pagination on the bestsales page only - not the entire site. Im quite new to code but hopefully someone can help.

 

Many thanks
