Well, I have a question if everyone's twiddling their thumbs at the moment?
Here goes...
I have a cfc stored in the session scope for a shopping cart app. It stores
various things, but I'll focus on the address bit. The user cfc has a
getAddress() function which returns a struct of the punter's address.
I have another cfc stored in the application scope. It should do all the
checkout stuff for the cart(*). One of its functions is (will be...)
doCheckout() which expects a struct of all the user's info.
Within this checkout.cfc, there is a private function,
insertAddressIntoDatabase(). It takes a struct and shoves it in the
database, returning the id of the row inserted. It should be called from
within doCheckout(), but never on its own.
Now, I'm a little fuzzy on how these cfcs talk to each other. Obviously I
need to pass the user cfc into the checkout cfc, but I'm not sure how... If
I pass in the user struct entirely, am I right in accessing it within the
arguments of the doCheckout function?
Vague code below. Does that look alright to everyone?
Many thanks for any input.
Geoff
(*) I wondered if the user.cfc should have the ability to check itself out
(see PetMarket), but that didn't seem right to me...
