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

If it is simply the total number, extended according to quantity, then 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:

        [perl]
            return scalar @{$Carts->{main}};
        [/perl]

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

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

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