Ok... I keep getting a "Variable SESSION is undefined" error when I do
this...
I have two functions in my .CFC -- setSessionVar and getSessionVar
setSessionVar has the following:
<cfset SESSION[ARGUMENTS.var_name] = TRIM(ARGUMENTS.var_value) />
(obviously var_name and var_value are arguments I pass in)
getSessionVar has the following:
<cfset var returnValue = "" />
<cfif StructKeyExists(SESSION, ARGUMENTS.var_name)>
<cfset returnValue = SESSION[ARGUMENTS.var_name] />
</cfif>
Now, the setSessionVar runs fine. Further, if I actually create a return
variable in the setSessionVar function and I assign the value of
SESSION[ARGUMENTS.var_name] to that return variable, I don't get any errors
and it returns exactly the data I sent.
Only when I call the getSessionVar function do I get the "Variable SESSION
is undefined" error...
On Ben Forta's blog, (here:
forta.com/blog/index.cfm/2007/11/15/Flex-And-ColdFusion-Session-Variables )
I found that someone was having the same problem I'm having with the
SESSION undefined errors, and Ben's advice was "it means that the
CFID/CFTOKEN or jsessionid cookies/URL parameters are not being passed, and
need to be." So where the heck do I get this information from, and where
do I pass it to?
HELP! I R CONFUSED! :-)
Thanks,
L.
