Logout Syntax Error

Report · May 26, 2009

Hi,

I working on a website with a login and logout set up. I have my login page working fine but I'm having an issue with the logout page. I have it set up so once I log in a "sign off" link appears, taking the user to the logout page. This is my logout.cfm code:

<html>
<head>
<title>Untitled Document</title>
</head>

<body>

Whenever I run this page, I get this error message;

Variable SESSION is undefined.

Does anyone know what I'm doing wrong?

Thanks in advance for the help.

How do you create the session variable?

<cfset session.username='#checklogin.username#'>
        Welcome <cfoutput>#session.username#</cfoutput> | <a href="logout.cfm">Sign Out</a>
        <cfquery name="updatelogin" datasource="mydata">
            update login
            set lastvisit=#now()#, visits = visits + 1
            where username='#session.username#'
        </cfquery>

Are you using an Application.cfc? Are you sure your session variables are not being timed out?

No, I'm not using Application.cfc and I doubt its timing out so soon.

Login.cfm code:

<cfif isdefined ("form.username")>
<cfset good=1>
    <cfquery name="checklogin" datasource="mydata">
        select username,pw
        from login
        where username='#form.username#' and pw='#form.pw#'
    </cfquery>

<cfif checklogin.recordcount is 1 and Compare(form.pw,checklogin.pw) Is 0>
<cfset session.username='#checklogin.username#'>
<cfquery name="updatelogin" datasource="mydata">
    update login
    set lastvisit=#now()#, visits = visits + 1
    where username='#session.username#'
</cfquery>
<cfelse>
    Incorrect login.
</cfif>
</cfif>

Logout.cfm code:

Error Message:

Variable SESSION is undefined.
