skip shipping page when weight is 0

[killerwhale65]

hi,

 

here is what i have on checkout_shipping.php:

// if the order contains only virtual products, forward the customer to the billing page as
// a shipping address is not needed
// ###### Added CCGV Contribution #########
//  if ($order->content_type == 'virtual') {
 if (($order->content_type == 'virtual') || ($order->content_type == 'virtual_weight') ) {
// ###### End Added CCGV Contribution #########	if (!tep_session_is_registered('shipping')) tep_session_register('shipping');
$shipping = false;
$sendto = false;
tep_redirect(tep_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL'));
 }

 

The problem is that when i have only products with 0 weight, i get a "page cannot be displayed". When there are products with weight there is no problem. When i uncomment the above, then it does work, also with 0 weight.

 

What is wrong?

 

And what is exactly a "virtual (weight) content type"?

 

Thanks!
