Help with Session Variables

Report · Jul 05, 2010

It has been a long time since I used CF, probably 5 years. I remember a lot but it seems I'm forgetting something.

I have a form that accepts user data. This data gets posted and another form comes up. Prior to the CFQUERY in the in the post, I set a session variable, just before the cflocation that brings the next form.

If I take out the scflocation, I can output the session variable.

But when the 2nd form comes up, the same session variable is undefined.

Any suggestions?

Thanks.

Suggestion number 1. Read the source code in the file with the next form. See if there is anything that clears the session.

Suggestion number 2. See if the file with the next form is part of the same application as the one where you set your session variable. If it's in a different one, check that Application.cfc file to ensure it allows session variables.

Maybe it is the application.cfm that I am confused about.

I have session management enabled.

My understanding is that all pages in the same directory as this application.cfm (which is my only one), are part of the same application.

Or do I need to identify the application name in each page?

Thanks again.

Your understanding is correct. However, your OP left an element of doubt regarding whether both files were governed by the same application.

To troubleshoot further, cfdump your session scope right before the cflocation tag, and then again at the very start of that other file. That may yield more clues.

For some reason, about 1/2 of my forms are

treated as a different application.

It has been about 5 years since I used CF. Has there been something changed? Do I need to add something to each form to force them to be seen as the same application?

Are all these templates in the same dir or a subdir of the one with the Application.cfm file in it?

Can you post the <cfapplication> line from said Application.cfm?

Page 1 is a form that accepts user data. I use email address as a key, so I pass I store it as session.email

Page 2 includes this:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<CFQUERY NAME="xxx"

DATASOURCE="xxx">

INSERT INTO merchant_master (email, status, company, contact, title, address1, address2, city, state,

zip, zip3, phone, password, website, descr, logo)

VALUES ('#form.email#', 'active', '#form.company#', '#form.contact#', '#form.title#',

'#form.address1#', '#form.address2#', '#form.city#', '#form.state#',

'#form.zip#', '#zip3#', '#form.phone#', '#form.password#', '#form.website#', '#form.descr#', 'xxx')

</CFQUERY>

</cfif>

Page 3. This is where session.email ends up being undefined:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

</head>

<body>

<cfoutput>#session.email#</cfoutput>

In Page 2, the database post, if I remove the CFLOCATION, I can display the value of session.email

I can not figure out why it becomes undefined in the following page.

Here is the application.cfm:

Thanks

When you <CFDUMP VAR="#SESSION#"> at the top of the third page, what shows up? Is it a blank structure, or does it show session ID and token data? If you put the cfdump before the CFLOCATION and comment-out the CFLOCATION, does that dump show the same session ID?

For grins and giggle, try putting addtoken="No" in the CFLOCATION tag to see if that changes things.

<cfif form.faction eq "sub1">
<cfset zip3 = left(form.zip,3)>
<cfset session.email = form.email>

I would do this instead:

<CFAPPLICATION NAME="fortwaynesavings" SESSIONMANAGEMENT="Yes" SESSIONTIMEOUT="#CreateTimeSpan(0, 0, 20, 0)#" clientmanagement="yes">

Add applicationTimeOut for formality, something like

application.cfm

Verify that the file's name is Application.cfm

Thank you for all of your help. Now I feel dumb. Chnaging application.cfm to Application.cfm took care of it. I'll do some more reading on Application.cfm.

All of your answers will help me better debug other things later on.

Thanks again
