Multiply 3 attributes to give the price?

Hello there Zenners

I have a problem, my client wants to multiply 3 attributes together to get a price, at the moment all the attributes do is add together all i require is a straight up multiplication of these 3 attributes.

I am semi skilled with zen cart however I have never come across this problem until now, any help or feed back is much appreciated.

here is a link to my site currently in development with the problem in question.

Probably not possible, unless you significantly adapt the whole attributes system.

see: http://www.zen-cart.com/forum/showthread.php?t=140653

It certainly is possible. You have to write a bunch of custom logic but it can be done.

Trust Scott on this one, then. He's written a couple of mods for me over the years and they've worked a treat.

Thanks you for the feed back lads much appreciated would anyone of you know where I should start to change the code?

It is a shame that something so powerful as Zen Cart does not have a multiply facility on it, I know where i would put it, right in the attributes controller in the box which only allows + and - values that would work a treat.

Thanks again

Attributes do have a "price factor" feature which multiplies the base price by whatever you specify; I don't know if three attributes with price factors would each multiply the base price and work together, but if they do, that might address your situation.

Multiplying attributes is only one of innumerable possible ways to want to have attributes interact, and there is no simple way to include a reasonable selection of these dependencies without bloating the code more (attributes are already one of the potentially most processing-intensive parts of Zen Cart).

Thanks mate I will look into it.

I had a look at the price factor and found it unsuitable for my needs, looks like i'll have to look into code :(

Too bad... Good luck with your work. If you get results, it would be valuable to post back and share what you find.

I understand attributes are going to be enhanced in v2.0. They will still not include dependencies, but it would be a really good idea if their code could be configured to easily hook in and insert custom dependencies. With the OOP coding focus of v2.0, that might be a possibility. We can hope!

indeed it would be a very good idea if we could add our own custom code in there, I did have a look at the attributes_controller.php but after about an hour of playing around I gave up.

I returned to my client and he have now found an alternative solution to possibly solving this problem using categories to narrow down the choices, only time will tell.

thanks for all your help
