ColdFusion Kinky eCards Update
Posted March 11, 2008 at 11:57 AM
Just fixed a small bug in my ColdFusion Kinky eCards Hayden Panettiere demo application. In the OnSessionStart(), I was clearing the session data. However, I was throwing the baby out with the bath water, so to speak, and was actually deleting the CFID and CFTOKEN as well. I am not sure if this was causing any bugs, per say, but I would definitely consider this to be a bad practice. Now, the new code, which can be downloaded from the Kinky eCards Project page has a modified OnSessionStart() event method that restores the CFID and CFTOKEN values after the SESSION scope is cleared:

- <cffunction
- name="OnSessionStart"
- access="public"
- returntype="void"
- output="false"
- hint="Initializes the user's session.">
-
- <!--- Define the local scope. --->
- <cfset var LOCAL = {} />
-
- <!--- Store the use ID / TOKEN values before we clear. --->
- <cfset LOCAL.CFID = SESSION.CFID />
- <cfset LOCAL.CFTOKEN = SESSION.CFTOKEN />
-
- <!---
- Clear the session. We should do this incase we
- are re-initializing.
- --->
- <cfset StructClear( SESSION ) />
-
- <!--- Restore the ID/TOKEN values. --->
- <cfset SESSION.CFID = LOCAL.CFID />
- <cfset SESSION.CFTOKEN = LOCAL.CFTOKEN />
-
- <!---
- Set up a struct to hold the form data. We the need
- the form data so that the user can go back and forth on
- multi-page forms (ex. enter data and preview eCard).
- --->
- <cfset SESSION.FormData = {} />
-
- <!--- Return out. --->
- <cfreturn />
- </cffunction>
