Pizza attributes - second opinion requested

[Ryk]

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 . 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

[Ryk]

Kim's got it in one!

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!

Hello Rick!

Where've you been hiding?

Have you opened a PizzaHut?

[Ryk]

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!
