btw, i just came across some of my code i wrote a few months back that's
a pretty slick example of the returnfuseaction tag.
<!---/orders/index.cfm--->
<cfdefaultcase>
<cfmodule template="#request.cfroot#/members/act_secure.cfm"
message="To checkout you must login, please do so now">
<cfinclude template="url_verifyaddress.cfm">
<cfinclude template="dsp_orderinfo.cfm">
</cfdefaultcase>
<!---url_verifyaddress.cfm--->
<cfif not len(trim(request.getuser.shipping_address_id))>
<cf_returnfuseaction
gotourl="#request.sslroot#/members/addresses/index.cfm?fuseaction=chooseshipping"
returnurl="#request.sslroot#/shoppingcart/checkout/index.cfm?order_id=#attributes.order_id#"
action="set">
</cfif>
This is part of the checkout script on http://www.ValueMusic.com. You
can see it in action by putting something in your shopping cart and
clicking "Checkout" (You don't have to actually purchase anything).
The /orders/index.cfm CFDEFAULTCASE actually calls the
cf_returnfuseaction tag twice.
Once in the act_secure.cfm, this checks to see if the user is logged in
or not, if not it'll send them to the login screen forcing them to
login. Once they've logged in, they'll be sent back to the
CFDEFAULTCASE
Then url_verifyaddress.cfm will verify that they have chosen a shipping
address. If they haven't it'll send them to the /members/addresses
circuit app and force them to choose (or add) a shipping address. Once
they've chosen a shipping address it'll send them back to the the
CFDEFAULTCASE and they can see their order form.
Does that make sense?
I'll make a tutorial walking through this process.
