Limited the total number of sales of a downloadable product?

[acpaulley]

I have played around with the settings for a while and have searched the forums here trying to figure out how to limit the total number of sales of a downloadable product without luck.

I can't seem to get the quantity to decrease whenever a sale is made of the downloadable product. I want to be able to sell X number of a certain downloadable product and then it's sold out.

If you have them setup correctly and use stock control, you can enter as stock the number that you wish to sell

Has anyone figured this out?

It seems Stock Control only allows you to manually reduce the number yourself.

How can you AUTOMATICALLY reduce the stock of a downloadable product?

Downloads do NOT track on Stock ...

You would need to customize the code in the order.php class for:

          if ((DOWNLOAD_ENABLED != 'true') || $stock_values->fields['product_is_always_free_shipping'] == 2 || (!$stock_values->fields['products_attributes_filename']) ) {
            $stock_left = $stock_values->fields['products_quantity'] - $this->products[$i]['qty'];
            $this->products[$i]['stock_reduce'] = $this->products[$i]['qty'];
          } else {
            $stock_left = $stock_values->fields['products_quantity'];
          }

currently the stock is not reduced on Download Products ...
