Cffunction scope in application.cfm?

Sorry, new to CF.

I created a cffunction in application.cfm, but I find I can't call it from other cfm files. I have application variables that I created and I can reference those, but trying to call the function gives me a "not found" error. I'm sure this is a scoping problem that I don't understand. How should I declare or reference the function to make it globally available?

No special declarations or references are needed. Calling the function on any page within the scope of the application file should work.

To verify this yourself, do the following test. Create a directory and place the files Application.cfm and testPage.cfm in it.

Application.cfm

<cfapplication name="cftest"

sessionmanagement="Yes"

setclientcookies="Yes"

sessiontimeout="#createTimeSpan(0,0,60,0)#"

applicationtimeout="#createTimeSpan(1,0,0,0)#">

</cffunction>

testPage.cfm

Now, run the test page. I expect the string to be output. My guess is that it failed in your case because you named your file application.cfm instead of Application.cfm.

That's it exactly! All of these projects have file "application.cfm" instead of "Application.cfm". I don't understand is why application variables could be referenced but not functions, but that is for another day...

If you're new to CF, you should not be using Application.cfm - use Application.cfc. The former is now depricated, the latter will allow you to do what you're after quite easily.

What I tend to do is wrap up all your similar functions into a CFC, then add that into the application scope during onApplicationStart. Create a CFC for your functions:

[myfunctions.cfc]

</cffunction>

</cfcomponent>

[Application.cfc]

</cffunction>

[index.cfm]

<cfoutput>#application.MyFunctions.doSomething()#</cfoutput>

Should do exactly what you're after. But ditch the Application.cfm.
