Hi Perrin,

I modified my add_item subroutine to incorporate the arrays. Can you see if I'm on the right track?

I believe that I'm way off base. Especially when it comes to the quantity field. Quantity is a parameter that is being passed. It's not in the database table so I don't know how to incorporate that into the array.

sub add_item
{
my @item_ref;
my @cart_ref;
my ($dbh, $cart_ref, $item_id, $qty, $color) = @_;
               
    # If the item isn't already in the cart, look it up from the datab
+ase
    # and store it in the cart as a new entry with a quantity of zero.
    if (!exists ($cart_ref->{$item_id}))
    {
        my $sth = $dbh->prepare ("SELECT item_id, description, categor
+y, price, picture, thumbnail, mime_type, color FROM catalog_pet
                                    WHERE item_id = ?");
        $sth->execute ($item_id);
        my $item_ref = $sth->fetchrow_arrayref ();
        $sth->finish ();
                                 
        return if !defined ($item_ref);    # this shouldn't happen...
        @cart_ref->[0] = {};    # create new entry, indexed by item ID
        @cart_ref->[1] = $item_ref->{description};
                                  @cart_ref->[3] = $item_ref->{price};
        @cart_ref->[8] = 1;
    }
    @cart_ref->[8] = $qty;    
                @cart_ref->[7] = $color;    
                push (@cart_ref, @item_ref);
}
