8.1. How do I get the number of items in a shopping cart?

If it is simply the total number, extended according to quantity, you can use the [nitems] tag. If you need this number for use in an embedded Perl script, you can use:

   $number = $Tag->nitems();

If it is the number of line items you need, then you can use a Perl script:

       return scalar @{$Carts->{main}};

(The 'main' refers to the main shopping cart.)

If you have SeparateItems in effect, and need the number of unique items, you could use:

       my $cart = $Carts->{main};
       foreach my $item (@$cart) {
   @items = split /\|/, $items;
   $count = 0;
   for (@items) {
   $count++ unless $seen{$_}++;
