Pizza attributes - second opinion requested

Price of pizza changes according to toppings.

Toppings are option values.

All toppings same price.

The logic behind the toppings should be:
a = Total amount of removed toppings added together
b = Total amount of extra toppings added together

If b=0 or b=a or a>b the price does NOT change.
if b>a then price=price+(b-a)

Can ZC be coded to do that with the option value prices without re-writing the whole thing?

I know we normally say just about anything can be done with the right skill, but this is proving a bit of a tricky one :D. I have asked someone who I know to be an expert and their response was no, but I'm just wondering if anyone else can think of a way to achieve this.

Or - thinking aloud - possibly a workaround ignoring the actual value (because they are all the same) and "simply" adding up the numbers of attributes applied and doing the calculation based on that?

Ryk,

Why the need for "remove" toppings??

Have std offerings and a build you own with

add 1
add 2
add 3
etc

... gotta' have the remove - I want a Cowboy pizza minus the onions plus olives and extra mushrooms

Kim's got it in one! :D

You should see the trouble we're having with the "Special Deals" ... Any 3 pizzas (from a range of 22) with choice of 3 sizes with the ability to add any of 32 toppings (at different prices depending on size) and remove any of an average of 4 toppings ... works out at a LOT of attributes...so many that the page grinds to a halt...oh how we long for attribute dependant attributes! :D

Hello Rick!

Where've you been hiding?

Have you opened a PizzaHut? :laugh:

Not hiding, just busy, busy, busy ... and not PizzaHut but a small chain of 100 stores in the London area.

It's been a very interesting project with ZC!:D

Have 2 options for each attribute:
'No onions' + 'With Onions'

'No Onions' would be the default and act as a 'remove' option.

Ah, if only it were that easy!

Part of the problem is that there are 32 different toppings available which could be added to any pizza, but each pizza starts with a different set of toppings (about 4 or 5).

And that still doesn't get around the calculation problem of only changing the price when the extra toppings > removed toppings when above the basic price.

But thanks for the suggestion - there may be a direction to go in here.

Rick, are these guys retired actuaries or bond traders? I've never heard of a pricing scheme this complicated (for pizza, for heaven's sakes!).

Rick, have you ever taken a kid into a major sweetshop? They can't see the wood for the trees when there are 100000000's of options...

... take them to the corner shop where there's only a handful of options, and they're just as happy.

... why not offer a range of pizzas - say, 15 or 20 - where the composition of toppings for each pizza option is standard for that option.

Then allow a smaller range of additions / subtractions per pizza...

I can't see somebody ordering a Hawaiian pizza (pinapple) with extra mushrooms, pepperoni, chicken, olives, anchovies, artichokes, butter, ice-cream, cod-liver-oil, baking powder, cream, persil, linguini.... :yuck:
