Problem with OnSessionEnd in Application.cfc

Posted on 2006-06-27

I'm trying to write to a database whenever the session ends. Basically it's just a log file, (time in and time out). The problem I'm having is it wont write to the db when the session ends. It doesn't seem to work when I use a variable containing the user id but it works fine if I hard code the id. Does anybody have any suggestions?

Code with variable:
<CFFUNCTION name="onSessionEnd">
   <cfquery name="qLog" datasource="MyDataSource">            
         UPDATE LOG
      LogOutDate = '#DateFormat(Now(),"mm/dd/yyyy")#',
      LogOutTime = '#TimeFormat(Now(),"hh:mm:ss tt")#'
      UserID = '#Session.UserID#' AND
      ID = (SELECT MAX(ID) FROM LOG WHERE UserID = '#Session.UserID#')

Hard coded works fine:
<CFFUNCTION name="onSessionEnd">
   <cfquery name="qLog" datasource="MyDataSource">            
         UPDATE LOG
      LogOutDate = '#DateFormat(Now(),"mm/dd/yyyy")#',
      LogOutTime = '#TimeFormat(Now(),"hh:mm:ss tt")#'
      UserID = '12345' AND
      ID = (SELECT MAX(ID) FROM LOG WHERE UserID = '12345')

I suspect that you have already cleared your session variables before calling the onSessionEnd function. Also, because users can leave without logging out, via a bookmark, closing the browser, etc. your logout times will be inaccurate.

on our website we track the login start time and the time the last request was made for that session.

Thanks Rob,
That's a good idea. I think I'll do that instead of using the onSessionEnd event. I was doing some reading on the net about the onSessionEnd event and it's a lot of talk about a bug in CF. It seems a lot of people are having issues with this event.

Anyway, thanks again for the idea.
