CFIF statement problems

[xstortionist]

I'm trying to set a default variable for a website I'm creating and this code isn't working.

Any help would greatly be appreciated.

Not sure why it wouldn't work, seems fine to me. You could try the CFPARAM approach. E.g.

<cfparam name="url.dealer" type="string" default="acura" />
<cfset variables.dealername = url.dealer />
<cfoutput>#url.dealer#</cfoutput>

That should work - but check it!

Thanks,
Mikey.

Thanks Mikey.

This was the answer we were looking for.

We tried to do the cfparam but we did it backwords.

Can someone explain how this code functions?

Thanks

What error are you getting?
It looks fine to me - although I tend to use single quotes isDefined ('URL.dealer')

Basically, if url.dealer doesn't have a value, the CFPARAM kicks in and populates url.dealer with the default value you specify. It's a really nice and clean way of supplying a default value instead of doing loads of CFIF etc. However, it is kind of limited in some ways.

Cheers!

I appreciate the breakdown Mikey. I'm saving this one in my memory banks.

You wouldn't believe how long we worked on trying to get this to work.

Referring to the docs is always handy to explain stuff:

<cfparam>

isDefined()
http://livedocs.adobe.com/coldfusion/8/functions_in-k_14.html

(or better) structKeyExists()
