That's a nice way of doing it...
I guess the only other problem I have is when I need to redirect as in
the following example:
1) User submits their address
2) My form checking cfc finds a field missing and so we need to redirect
back to the checkout and include an error message
I guess the cfc could return the pagename to redirect back to?

Its not especially long winded, you are going to have to check each action
regardless or how you do it.
You could however do it like this.
All your buttons are called CartAction with the action as the value
E.g.
<input type="submit name="CartAction" value="AddToCart">
<input type="submit name="CartAction" value="RemoveFromCart">
And just pass that action to your CFC, and the rest of the form fields as
the arguments, thus doing away with all your cfinvokes below.
E.g.
<cfif StructKeyExists(form,'CartAction')>
<cfinvoke component="shoppingcart" method="#form.CartAction#"
argumentcollection="#form#"></cfinvoke>
</cfif>

Subject: [CF-Dev] form handling
- see footer for list info -<
Hi all,
I have a shop/cart app I developed a while ago and I'm updating.
There are various steps to purchase (choose / update / checkout / buy /
etc...) with forms controlling each. I originally developed it so that the
form submits are handled by a single file which invokes CFC's or redirects
as necessary. It does this as follows:
<cfif IsDefined("form.buy")>
<cfinvoke ...>
<cfelseif IsDefined("form.updateCart")>
<cfinvoke ...>
<cfelseif IsDefined("form.clearCart")>
<cfinvoke ...>
<cflocation...>
and so on.
This seems a bit longwinded. My question is: is there any better way of
handling lots of related forms?
Thanks, Damien
