[ic] Calculating quantity of items

[Tim Mirecki]

Hey Kyle:

Thanks it works quite well with Interchange 4.7.2! However there is one very
minor issue. I have links that are updating another frame on the site to add
them to the cart. (using something like this:  a
href="mv_order_item=code&mv_action=return" target="top") This allows the
user to rapidly add items to the cart. Sometimes it will combine SOME of the
items, but not all. I even got it into three groups once, so that the same
item was listed 3 times, each one with a different quantity (This is fine,
however, since the total quantity is correct).

I can live with this, I don't really see it as being a problem...we'll see.

If you have any suggestions, please let me know. Thanks for the help!

Tim

You could use a custom usertag like the one below.
Set seperateitems to yes in catalog.cfg
and add the tag [basket_combine] at the top of the
basket page.

Note: this worked with MV 3 and 4, have not tried with IC, but
I believe it should work.

UserTag basket_combine Order quantity
UserTag basket_combine Routine <<EOR
sub {
my $cart = $Vend::Items;
# Combine all similar products if attributes match
for (my $x=0;$x < @$cart;$x++) {
  REMAIN: for (my $y=$x+1;$y < @$cart;$y++) {
    # now check if 'code' (sku) matches
    next REMAIN unless ($$cart[$x]{code} eq $$cart[$y]{code});
    foreach (keys %{ $$cart[$y] }) {
          # now check that all attributes match (except qty of course)
      next REMAIN unless ($_ =~ /quantity/i ||
        $$cart[$x]{$_} eq $$cart[$y]{$_});
    }
    # we have checked all atb's match, so combine item qty's
    $$cart[$x]{quantity} += $$cart[$y]{quantity};
    # now remove this duplicate
    splice(@$cart, $y, 1);
  }
}

return '';
}
EOR
