Check for URL Parameter

[AlanDI1]

I have CF module that may or may not be passed a parameter in the URL. I want to check and see it the parameter is there otherwise use a default.

<cfif isDefined("URL.SelectDate") >
<cfset lnSelectCYCYMM = #URL.SelectDate#>
</cfif>

This code produces "This page cannot be displayed" message.

Can anyone tell me how to fix it or another way to check for the existance of the parameter.

Thanks

<CFPARAM NAME="url.SelectDate" DEFAULT="2005-12-11">
<CFSET lnSelectCYCYMM = url.SelectDate>

If you still want to use CFIF's you can do:

<cfif isDefined("URL.SelectDate")>
    <cfset lnSelectCYCYMM = #URL.SelectDate#>
<cfelse>
    <cfset lnSelectCYCYMM = "12/10/2005">
</cfif>

i prefer CFPARAMs because you canmake them "cascade"

let's say that you want to pick up a parameter value form either the user's cookie or the url, but if the url parameter is specified, it has priority

<CFPARAM NAME="cookie.SelectDate" DEFAULT="2005-12-11">
<CFPARAM NAME="url.SelectDate" DEFAULT="#cookie.SelectDate#">
<CFSET lnSelectCYCYMM = url.SelectDate>

to do the same with CFIFs is substantially messier

r937, I agree CFPARAM NAME is the better way of doing things. But my solution was just in case AlanDI1 wanted to use <cfif></cfif>
