Hi, beginner here, so bear with me if i sound confused!

I'm trying to store the variables of a form in session variables, and am
having trouble changing the variables. At the moment, the process is a follows:

1)User Logs in and starts completing form, default session variables assigned:
<cflock timeout=20 scope="Session" type="Exclusive">
    <cfparam name="SESSION.fname" default="default">
    <cfparam name="SESSION.lname" default="default">
</cflock>

2)User submits form, which updates session variables to the values in the form
<cfloop list="#form.fieldnames#" index="i">
        <cfoutput>
        <cflock timeout=20 scope="Session" type="Exclusive">
            <cfset SESSION.i = #evaluate("form.#i#")#>
        </cflock>
        </cfoutput>
</cfloop>

However, when i then try to check the contents of the session variables after
the form has been submitted, the contents of the session is still the same as
set in the default.

Session management is turned on in the application.cfm, and in the CF
Administrator. I'm running out of ideas now...

Any help would be brilliant.

Thanks.
Tom

How about changing this?

<cfset session.i = #evaluate("form.#i#")#>

to

<cfset #evaluate(session.i)# = #evaluate(form.i)# />

If that doesn't work, surround the "i"'s by pound signals.

Hopefully, that does the trick. Thanks!

If i try <cfset #evaluate(session.i)# = #evaluate(form.i)# /> I get the error

: "Can not assign a value to a function.

Unable to assign a value to the function "evaluate" on line 9, column 33 "

If i then encapsulate the "i"'s with pound signs i get : "A CFML variable
name cannot end with a "." character.
The variable session. ends with a "." character. You must supply an additional
structure key or delete the "." character. "

Thanks for help so far, any more would be great.

you'll want this :

<cfset "session.#i#" = evaluate("form.#i#")>

Have fun! =)
