calling a dynamically named cookie

[wycks]

Hi,

I'm trying to create a dynamic variable and then call it dynamically and I don't know if this is possible.  The easiest way to explain what I'm trying to do is to show what I want to do but obviously doesn't work.

<cfcookie name = "variable#rsSet.variable_id#" value="cookievalue">

and then later I want to call it by doing something like

<cfoutput>#cookie.#rsSet.variable_id##</cfoutput>

but obviously that doesn't work.  Is there a way to call the cookie without typing the exact name of the cookie?

Thanks,

Mike

ok so i found out how to call the variable using

                <cfoutput>evaluate("cookie.#rsSet.variable#")</cfoutput<

but now my problem is that I need to check to see if it is defined so what I want to do (but obviously can't) is:

<cfif isDefined("evaluate("cookie.#rsSet.variable#"))

is there a way to check to see if the dynamically named cookie is defined?

Thanks

In this scenario, structkeyExists is perhaps better than isDefined. Something like

<cfif structKeyExists(cookie, rsSet.variable_id)>

</cfif>

I always use StructKeyExists(), never use isDefined() as I've heard of issues with it.

V/r,

that worked, thanks

BKBK should get credit for this, not me.  BKBK provided the suggestion, I just agreed.

Thanks for the mention, WolfShade​. I am happy it works.

Do you mean <cfcookie name = "#rsSet.variable_id#" value="cookievalue">?

If so then you could just do:

<cfoutput>#cookie[rsSet.variable_id]#</cfoutput>
