MySQL/PHP database price configuration

[iteachlife]

Any ideas on how to figure pricing for an ecommerce site that would sell products based on a square foot price instead of a "fixed" price.(I currently have a site in PHP/MySQL database). I would use a base price for an item and convert the width * height * the base price. It gets more complicated because of "add ons" that are also figured by a square foot price as well. I have a site that sells custom made to order cabinet doors and wood related products. Depending on style, size, options.... determines the price. Any ideas or if you have crossed this bridge before I'd like to pointed in the right direction. Thanks in advance!

Since you pretty much described the solution in your question, what seems to be the difficulty?
