Nested delimiters (#)

[JakeFlynn]

I created a bunch of vars using a loop and named them: X#LoopCount# so you
end up with X1, X2, X3... all as variables. Now I want to use a loop to go back
through and access each value:

<cfloop index="LoopCount" from="1" to="#max#">
<cfoutput>#X#LoopCount##</cfoutput>
</cfloop>

This obviously does not work. Does anyone know of a work around? Thank you for
your time.

You can either:

Evaluate the item e.g. #evaluate('X' & LoopCount)# which isn't really
recommended, as it has performance issues.

or

Scope the variable #variables['X' & LoopCount]# (this works for all most if
not all CF structures)


e.g
<cfset X23 = "hello">
<cfset LoopCount = 23>

<cfoutput>#variables['X' & LoopCount]#</cfoutput>

stpaz,
I had to use your first (evaluate) option because I was working with cookie vars. That did the trick, thanks!

One last question how would you check if it is defined incrementally?

isdefined does not work with #evaluate('X' & LoopCount)#...

Don't use evaluate, just reaplace variables for cookie eg #cookie['X' & LoopCount]#

try this:
isdefined("X#loopcount#")

[JakeFlynn]

try this:
isdefined("X#loopcount#")

That did the trick thanks again stpaz
