Yes it does help, Isaac. You're right. And I had learned that about iif,
but since I never had use for it before, it was away in the dusty corners of
my memory. Now the code is even more concise, to replace the 15 lines of
code in my original post, and boils down to this:
<cfformgroup type="horizontal" label="Preferred Payment Method:">
<cfinput type="radio" name="PaymentMethod" value="Visa" Label="Visa"
checked="#iif(order.getpaymentmethod() IS
'Visa','true','false')#" >
<cfinput type="radio" name="PaymentMethod" value="Mastercard"
Label="Mastercard"
checked="#iif(order.getpaymentmethod() IS
'Mastercard','true','false')#" >
<cfinput type="radio" name="PaymentMethod" value="Amex" Label="Amex"
checked="#iif(order.getpaymentmethod() IS
'Amex','true','false')#" >
</cfformgroup>
I think the new XML forms would have to be one of the least publicised
wonders of CFMX7. It's revolutionised the way I collect data.
And if you put the skin attribute as a application variable, you can
standardise the look of forms all over your site, and change the whole look
everywhere with the change of a single variable. For example:
in Application.cfm or Application.cfc have the following somewhere:
<cfset application.formskin = "blue" />
Then in every form on the site you have this as the <cfform tag:
<cfform action="#cgi.script_name#?#cgi.Query_string#" method="post"
name="whatever" format="XML" skin="#application.formskin#">
stuff
</cfform>
Change the value of application.formskin and behold! All the forms on your
site change their look and feel together. Easy code reuse!
WONDERFUL!!
