Nah, sorted...
I did it like this:
Each item has a title, recorded in the oiption_title table. This stores the
item_id and the option title. Then i have the options table which references
the option_id from the option_title table.
The option table contains price and member price as well and contains it's
own option_selected id field.
Then when I add items to the cart, I have a form on the shop index page
(which doubles as a display form for each item (depending of the $_REQUEST
value of the item_id)).
The form displays the options (if there are any) and upon submission of the
form adds the option_selected to the shopping cart variable like this:
key: 41:32:96 etc
so the first number (41) is the item id and all the others are just options.
So 32 might be "red" and 96 might be "extra large".
Then when working out the total, I find out whether the user is logged in,
if they are I see if any of the options has made the price unequal to the
default item price (also set by the administrator). Then I can either add
the default price, or the price associated with that option.
Hope this helps if anyone else ever has this problem.
But after ages trying to work out a way to do it I'm rather disinclined to
share the exact code... Sorry.
