Re: Weights change by size, and multiple sizes
Well, I spoke a little bit too soon, I suppose... :)
One thing I had to change was the that the tallying of the weights
should also include:
$weight += $item_weight * $item->{quantity};
It wasn't dealing with multiple quantities as it was given below.
Like that game where you hit the head with the mallet when it pokes up,
another head has just popped up and I'm too feeble to knock it down.
We now have the total shipping weights being calculated correctly in the
basket. However, when it comes to checking out, no shipping weights are
listed or used as a lookup.
This would obviously be the case because our total weight is determined
by a lookup and sum of each item with this User Tag in the shopping
cart. However, on Checkout, the [shipping] tag then knows nothing about
it (so no lookups are performed in the shipping.asc database) which
means the total cost knows nothing about it either (nor any taxes added
to the shipping).
Is there some way to communicate a User Tag's returned value (the total
shipping weight of all items) to the [shipping] tag?
I'm assuming that shipping weights for the items are not stored in a
referenceable format, but are instead re-looked-up when [shipping] is
called, so it seems unlikely. Meaning, there's no way I can I alter
this User Tag below to define a variable with each item's weight to be
used by [shipping] down the road... ??
I have a feeling I'm missing something fundamental in my slowly growing
understand of how this is all tied together.
Any help someone could give would be pure bliss (but I promise not to
make a mess).
Thanks!
