global radio checkbox if ticked checks the cart for products

[malik_dev]

Hello all!

I'm new to php and zen, i think it's a fantastic product as it is but i'm interested in customising it a little to provide a specific functionality.

i think the following walkthrough will explain:

- the customer either ticks a checkbox or selects a yes or no radio box in answer to a question (do u want to build a pc?)

- this then sets a global variable ( yes i do or no i dont)

- if set to yes, it advises the customer to select from particular sub categories of hardware (ie: cpu, memory, graphics card, power supply, case, monitor etc)

- a final check is then performed on the cart to see if particular parts have been selected

- if yes it goes to payment, else back to choosing at least 1 product from each subcategory.

question 1: how do i set a global variable selected by the user to YES or NO?

question 2: how do i display products from each subcategory under hardware as a drop-down list?

question 3: how do i check the cart for at least one item being selected from a sub category?

Might be simpler to use the PC Configurator addon from the Downloads section - Note: I have not installed it myself so I can not vouch for it.
