Subroutine: display_products_for_sale

Our frontpage has the same layout as our Product pages; it includes two
links (text and graphic) that allow the customer to view their cart. If
I viewed the cart from the frontpage and then clicked on "Continue
Shopping", I got a "document contained no data" error because $page was
null. I added a line to this routine to display the frontpage if $page
is null.

                # If the store is HTML-based and there is no current
                # keyword however, the script simply displays the page as
                # requested with display_page which will be discussed
                # shortly.
         
    if ($page eq "") { &output_frontpage; exit; }
    &display_page("$sc_html_product_directory_path/$page",
                  "Display Products for Sale", __FILE__, __LINE__);
    }

Subroutine: add_to_the_cart

Because some of our product pages have multiple items on them, I wanted
to allow customers to submit quantities of zero. I changed the following
part of the routine, as indicated by arrows, to allow that. Quantities
of zero are not added to the cart.

    if (($item =~ /^item-/i ||
        $item =~ /^option/i) &&
-->        $form_data{$item} ne "" &&
-->        $form_data{$item} ne "0")
      {

                # Comments...

        $item =~ s/^item-//i;

        if ($item =~ /^option/i)
          {
          push (@options, $item);
          }

                # Comments...

        else
          {
-->      #    if (($form_data{"item-$item"} =~ /\D/) ||
-->      #        ($form_data{"item-$item"} == 0))
-->           if (($form_data{"item-$item"} =~ /\D/))
            {
            &bad_order_note;
            }
          else
            {
            $quantity = $form_data{"item-$item"};
            push (@items_ordered_with_options, "$quantity\|$item\|");
            }
          }
        } # End of if ($item ne "$variable" && $form_data{$item} ne "")
    } #End of foreach $item (@items_ordered)

Subroutine: display_price

On a 640x480 resolution screen, the prices in the last column of a cart
table were displaying on two lines. I added a non-breaking space to this
routine to prevent that. (Since we only us U.S. dollars, we put the
money symbol in front of the price. You could make the same modification
to the "else" part of this routine, too.)

  if ($sc_money_symbol_placement eq "front")
    {
    $format_price = "$sc_money_symbol"." "."$price";
    }
