Form on coldfusion page losing form variables

OK, I am having a very strange problem. Several applications
on our
production web servers have started manifesting the same
symptom. On
the login page, you have a couple of fields for account name
and
password. When you hit submit the action page says it can't
find the
form variables. These are on a cluster. If you go to the
servers
individually, then everything works as it should. Our network
people
claim that we are not shifting from one server to the other.
Has anyone
else ever seen this behavior before on a single
server?

These are stand-alone servers that being load-balanced. They
are supposed to stuck on the same server until the session ends. If
we go to the individual servers and run the applications, it works.
Otherwise, it fails randomly.

You did not write if you are using any cluster features of
ColdFusion, but I assume you are using as stand-alone configured
ColdFusion servers, and through LoadBalancer configuration (sticky
cookie) you are making sure that users are always sent back to the
same server.
I would not expect the problem you have to be caused by such
a load balancer configuration, but companies who implement load
balancers often also use Proxy-servers, and now well they can mess
up a lot of things with caching.
(even Dan's problem could be caused by a proxy server: first
request to verify if the requested page still has the same date,
and then the request is actually sent to the server itself for
execution).
A quick way to verify if a proxy is messing with you is to
attach any URL parameter: "www.mysite.com/index.cfm" may be cached,
but "www.mysite.com/index.cfm?user=12345" should not be served from
the cache and instead get sent to an actual web-server to return a
customized response.
Cheers,
fober

How do I pass a username form variable from a drop down list/menu to another page?

Hi,
I have a login_success.php page that has a drop down list/menu (which lists usernames). I want the user to click on their user name, and when they click the submit button the username information to be passed over to the username.php page which will contain a recordset, sorted by username.
How do I pass the username info from the drop down list/menu to the username.php page?
The drop down menu is connected to a recordset listUsername, I have filtered the recordset with the Form Variable = username, and I have used the POST method to send the username to the page username.php. I'm not sure how to structure the php or which page to place it on.
<form id="form1" name="form1 method="post" action="username.php">
     <label for="username_id">choose username:</label>
     <select name="username_id" id-"username_id">
          <option value="1">username1</option>
          <option value="2">username2</option>
          <option value="3">username3</option>
          <option value="4">username4</option>
     </select>
     <input type="submit" name="send" id="send" value="Submit" />
     <input type="username" type="hidden" id="username" value="<?php echo $row_listUsername['username']; ?>" />
</form>
Could somebody help me please?
Thanks.

I would not post the variable over, In this case I personally would send it through the URL and use the $_GET method to retreve it. For Example.
<html>
     <head>
          <title>Test Page</title>
          <script type="text/javascript">
               function userID(){
                    //var ID = form1.userIDs.selectedIndex;
                    var user = form1.userIDs.options[form1.userIDs.selectedIndex].value;
                    window.location = "test.html?userID=" + user;
          </script>
     </head>
     <body>
          <form id="form1">
               <select name="userIDs" id="userIDs" onchange="userID();">
                    <option>Select a User</option>
                    <option value="1">User 1</option>
                    <option value="2">User 2</option>
                    <option value="3">User 3</option>
                    <option value="4">User 4</option>
               </select>
          </form>
     </body>
</html>
//PAGE TO RETRIEVE THE USERNAME
<?php
if(isset($_GET['userID'])
     $userID = $_GET['userID'];
     echo $userID;
     die;

How to pass a form variable from page to page

I have a series of 4 forms on 4 pages that update a database.
A variable from one of the forms (doesn't matter which one, if it's
easier one way over another, let's go that way) is passed to the
last page, where a PayPal button will appear based on the value of
the form variable. I am using ASP javascript and an Access
database.
Thanks.

Either store the variable in a hidden field in the
intermediate forms,
or use a session variable.

CF Set form.variable for query and Next/Previous pages error

I have a CF form with a select that posts to a CF "action" page.
On the action page I: CFSET ItemNumber=#form.ItemNumber#
I CFOUTPUT the 'ItemNumber' into the CFQUERY (which is an Inner Join dependant on the '#ItemNumber#')...
All of the above works just fine and displays the database fields in color alternating rows, per the rest of the code.
Here's the problem:
I'm displaying 40 rows on a page per "Next and Previous" code. (CFPARAM name="start" default="1" and CFPARAM name="disp" default="40" along with the rest of the NextN code in the header and body). This does display 40 rows on the page and puts a link at the bottom of the page "Next 40 Rows", etc.
Note: I'm only querying the database once and using the query (query name="data") to populate the table rows And the NextN code (CFOUTPUT name="data") And (CFIF start + disp GREATER THAN data.RecordCount, etc)...
The problem happens when you click the "Next 40 Rows" link to display the 2nd page of rows. Since (I'm assuming) this NextN code is 're-reading' the same page from top to bottom, an error is thrown when the code tries to read the CFSET ItemNumber=#form.ItemNumber# at the top of the page.
With the #form.ItemNumber# on this action page Originally coming from the previous posting of the form to this action page, when the "Next 40 Rows" link is clicked and the NextN code re-reads this action page - the CFSET ItemNumber (#form.ItemNumber) is not getting populated and throws the error...
I hope I've not made this sound confusing.
I can get the NextN code to work when I'm just querying the database without "flying in" a form variable. But when I CFSET a variable (#form.ItemNumber#) that is inserted into the query, the second page of the NextN throws an error and doesn't display.
I would include the page code here but it would be fairly lengthy and, as well, the NextN code is a 'standard' CF code -- I've narrowed the problem down to the above "Element is undefined" (when the page tries to reload from the "Next 40 Rows" link) and am hoping there's a simple fix or another way to display the records in Next and Previous pages.
Thanks to anyone in advance for shedding light on this.
- e

Thank you for the reply, Owain.
Yes - The Next/Previous at the bottom of the page are hyperlinks.
<a href="ThisPage.cfm?start=#Evaluate("start + disp")#">
The following is at the top of the page (and is the variable from the form that I CFOUTPUT in the query):
<cfparam name="ItemNumberDropdown01" default="">
<cfset ItemNumber = #form.ItemNumberDropdown01#>
The error report showed that the "Next Page" hyperlink was reading an undefined variable... although when the "action page" first opens from the form posting to it, it populates the CFSET just fine (per the cfparam and cfset above)... As you mention, the hyperlink clearing the form scope is what causes the error in trying to display the next set of records...
The form page and the 'action page' are both secure pages with an application page setting the session, etc. Am I at risk in using an URL scope?
Where would this URL scope be put? (The href is shown above - would the URL scope go in this? - How would this be written?)
The CFPARAM and CFSET would still exist at the top of the 'action page' and still throw an error wouldn't it or would this be replaced with something else to read the form.variable for this 'first' action page to be displayed?
Thanks again for the 'education' on this...

My simple form page isn't passing along the form variable I need to load my update page?

I have created a recordset on my update page that specifies a form variable filter that matches the form ID on my simple form page. When I enter the information on that page and submit, I go to the update page but nothing is loaded. I've tested the update page using a URL parameter and it loads perfectly. Why isn't my form variable working?

Thanks for responding. Here's the code. I can't help with the url since I'm running on MAMP.

Lightwindow passing form variable to action page

Hi,
I have a form that is popup using lightwindow to allow users to fill out the form. For some reason, I couldn't get the form.variables to pass to the action page and insert into a database. Anyone has suggestions or ideas?
thanks.

link to open lightwindow pop up page. of course i've all the js required on the top of the page
<a href="form.cfm" params="lightwindow_width=500,lightwindow_height=600" class="lightwindow page-options">Form</a>
here is the form
<form id="form1" name="form1" method="post">
<p><label for="fname">First Name</label><input type="text" name="fname" id="fname" class="inputText" /></p>
<p><label for="lname">LastName</label><input type="text" name="lname" id="lname" class="inputText" /></p>
<p><p><a href="hello.cfm" params="lightwindow_form=form1" class="lightwindow_action" rel="submitForm"><button>Submit</button></a> or <a href="#" class="lightwindow_action" style="color: blue;" rel="deactivate">Cancel</a>
</p>
here is the action page for the form (hello.cfm)
<cfoutput>#form.fname# | #form.lname#</cfoutput>
I do not know if this is out it's supposed to do it or not but the form variables are not passing over to the action page.
thanks

Trying to move a list of form variables to session variables of the same name

I am trying to move a list of form variables to session variables of the same name and I am having a lot of trouble.
I have never had to post of this forum with a language question in all the 10 years I have been using ColdFusion. I was a qa Engineer @ Allaire/Macromedia back when it was going from one to the other. I have a pretty good grasp of the language.
I have software that runs off a list. The fieldnames are variable and stored off in an array. It's survey software that runs off a "meta file". In this example; I have the number of fields in the survey set to 12 in the "metafile". I have each field declared in that file in array Session.SurveyField[1] and the above loop works fine. I include this "metafile" at the start of the process.
I cfloop around a struct and it works wherever I have needed to use it; such as here - writing to the database for example;
<CFQUERY NAME="InsertRec" DATASOURCE="Survey">
INSERT into #variables.SurveyTableName#
(EntryTime
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
,#Session.SurveyField[arrayindex]#
</cfloop>

   VALUES
    ('#EntryTime#'
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thisname = "Session." & Session.SurveyField[arrayindex]>
,'#evaluate(variables.thisname)#'
</cfloop>

</CFQUERY>
NOW HERE'S THE PROBLEM: I am running into trouble when trying to move the form variables to session variables of the same name. It is the only part of the software that I still need the datanames hard coded and that is a roadblock for me.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thissessionfield = "Session." & Session.SurveyField[arrayindex]>
<cfset thisformfield = "Form." & Session.SurveyField[arrayindex]>
<cfset #thissessionfield# = #evaluate(thisformfield)#>
</cfloop>
I have tried it with or without the "evaluate"; same result. It doesn't give an error; it just ignores them (session variables look as such in the next page in the chain)
q01_name=
q02_acadtechorna=
q03_water=
q04_firstaid=
q05_cpr=
q06_lifeguard=
q07_aed=
q08_projadv=
q09_color=
q10_santaclaus=
q11_supervisor=
q12_supervisoropinion=
Note: they exist because I CFPARAM them in a loop like the above at the start of the procedure) - and this works just fine!
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset dataname = "Session." & Session.SurveyField[arrayindex]>
<cfparam name="#variables.dataname#" default="">
</cfloop>
</cflock>
I EVEN tried exploiting the Form.Fieldnames list using CFLoop over the list and the same sort of logic within and it still gives me nothing....
Here's the FORM.FIELDNAMES value
"Q01_NAME,Q02_ACADTECHORNA,Q03_WATER,Q04_FIRSTAID,Q05_CPR,Q06_LIFEGUARD,Q07_AED,Q08_PROJAD V,Q09_COLOR,
Q10_SANTACLAUS,Q11_SUPERVISOR,Q12_SUPERVISOROPINION"
Here's the logic; SAME RESULT - The session variables don't get set.
<cfoutput>
<cfloop list="#Form.FieldNames#" index="thisfield">

<cfscript>
thisSESSIONfield = "Session." & thisfield;
thisFORMfield = "Form." & thisfield;
#thisSESSIONfield# = #thisFORMfield#;
</cfscript>
</cfloop>
</cfoutput>
The CFPARAM in a loop with variable output name works just fine; so does the post (which I included above) as does the SQL Create, Param Form Variables, Param Session Variables, etc.
THIS even works for moving BLANK to each session variable, to zero them all out at the end of the process;
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
</cfscript>
<cfset #thissessionfield# = "">
</cfloop>
</cflock>
Expanding on that code, you would think this would work, but it doesn't;
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
thisformfield = "Form." & thislocalfield;
</cfscript>


<cfoutput>
<cfset #thissessionfield# = "#evaluate(thisformfield)#">
</cfoutput>
</cfloop>
And see that debug code in the middle? To add insult to injury... When I uncomment that it shows me this. So it certainly looks like this should work....
Session.q01_name = "Me"
Session.q02_AcadTechORNA = "N/A"
Session.q03_Water = "Yes (certificate expired)"
Session.q04_FirstAid = "Yes (certificate is current)"
Session.q05_CPR = "No"
Session.q06_LifeGuard = "Yes (certificate expired)"
Session.q07_AED = "Yes (certificate expired)"
Session.q08_ProjAdv = "Yes (certificate expired)"
Session.q09_Color = "Gray"
Session.q10_SantaClaus = "Yes"
Session.q11_Supervisor = "Da Boss"
Session.q12_SupervisorOpinion = "Not a bad thing"
There must be some simpler way to do this. This way won't work against all odds even though it seems so much like it should.
So I end up having to hardcode it; still looking for an automated way to set these #@%$*@!## session variables over the list from the form variables of the same @#@!$#%$%# name. Do I sound frustrated???
No matter what I do, if I don't HARDCODE like this;
<cfset Session.q01_name = Form.q01_name>
<cfset Session.q02_AcadTechORNA = Form.q02_AcadTechORNA>
<cfset Session.q03_Water = Form.q03_Water>
<cfset Session.q04_FirstAid = Form.q04_FirstAid>
<cfset Session.q05_CPR = Form.q05_CPR>
<cfset Session.q06_LifeGuard = Form.q06_LifeGuard>
<cfset Session.q07_AED = Form.q07_AED>
<cfset Session.q08_ProjAdv = Form.q08_ProjAdv>
<cfset Session.q09_Color = Form.q09_Color>
<cfset Session.q10_SantaClaus = Form.q10_SantaClaus>
<cfset Session.q11_Supervisor = Form.q11_Supervisor>
<cfset Session.q12_SupervisorOpinion = Form.q12_SupervisorOpinion>
I always get this from my next page because the session variables are empty;
You must answer question 1.
You must answer question 2.
You must answer question 3.
You must answer question 4.
You must answer question 5.
You must answer question 6.
You must answer question 7.
You must answer question 8.
You must answer question 9.
You must answer question 10.
I tried duplicate as well, but I can not get the above to work...
Can anyone help me do this thing that one would think is simple????

I think if you use structure array syntax you should get the results you want.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
      <cfset session[Session.SurveyField[arrayindex]] = Form[Session.SurveyField[arrayindex]]>
</cfloop>
Or probably even easier.
<cfset session = duplicate(form)>

Using HTML, what happens to form variables on submit?

If I create a simple AIR app that has two files, lets say index.html and next.html, how would I pass form variables from one page to the next since there is no server side scripting?
Can it be done via javascript somehow, by maybe saving the variables from the first page and then retreiving them on the second?
Here a sample of what I am trying to accomplish:
index.html
<html>
<body>
<form method="GET" action="next.html" name="theName">
Name:
<input type="text" name="textField">
<input type="submit" value="submit" name="submitButton">
</form>
</body>
</html>
next.html
<html>
<body>

</body>

Form Variables Don't Pass for Some Clients

Recently, I’ve noticed some problems on one of my pages
where form field variables aren’t passing to my action page.
As far as I can tell, this is a new problem.
This is the error I’m getting:
Error resolving parameter FORM.EMAIL
The specified form field cannot be found. This problem is
very likely due to the fact that you have misspelled the form field
name.
The error is thrown when a cfquery is unable to find the form
variable.
The query looks, basically, like this:
<cfquery name="Iogin" datasource="dsn">
SELECT Count(*) AS Match
FROM Users
WHERE users.email = '#FORM.email#'
AND users.password = '#FORM.password#';
</cfquery>
I know I could squash these errors with a cfparam or with
other error checking, but what I’m really concerned about is
why the form variables aren’t there. I have tested the form
on a number of my internal clients and have not been able to
replicate the error as it is being triggered from outside clients.
I am able to submit a blank form or a complete form without any
errors being thrown. I have established that the form submissions
are coming from my site and are not being submitted by an outside
domain.
QUESTIONS:
1. Does anyone know what might be happening to cause the form
variable to disappear? Shouldn’t all the forms variables be
submitted when a user hits the submit button, regardless of whether
there is data in the form field?
2. Could a firewall on the clients’ end be withholding
the form variables without notifying the user?
3. Have there been any recent changes to browsers that could
be holding back form variables?
Any help would be greatly appreciated!

@Azadi
quote:
from your posts it looks like this happens to different forms
in your application (you mentioned the email field and also a
select box, which is presumably in some other form)
I was able to resolve the problem with the second form (the
one with the select box, not the one posted above). A JavaScript
resided on that action page which triggers a service. The service
(similar to GoogleAds) receives the page’s url from the
JavaScript and then the service comes back and loads the page to
evaluate the page’s content. The result: Action pages being
loaded with no form content. My error reporting, very similar to
what insuractive suggested, helped solve this problem.
HOWEVER, we still periodically have trouble with the other
form. I know from speaking with at least two users that the problem
is a direct result of users following the planned application
flow—form to action page. So this discussion is still
relevant.
@insuractive
quote:
you should make sure you test to see what happens when the
client has javascript and/or cookies disabled on their browser.
This is a good thought. I’m embarrassed to say that I
haven’t tried accessing this form with cookies and JavaScript
turned off. I will try this and report back.
Thanks to all of you who are offering suggestions.

Passing FORM variables through CFSET

I am writing an account creation page for my site. After the
user inputs the required information, I would like to 1. confirm
that their email is not a duplicate of another user 2. Pass them
off to another page that allows them to confirm the information
that they input and submit the info to the database. I would like
to have the email confirmed on that page through passing the
FORM.email variable to the #CGI.SCRIPT_NAME#. If the RecordCount on
the query for duplicate email addresses comes back VALUE=0, use
CFLOCATION to pass to the next page with the FORM variables intact.
However, as forms can only have one action attribute, what is the
best way to do this, in your opinion?
Thanks so much for your help!
dan

use session var to store form data:
- user submits form.
- form posts to same page (to itself).
- check for duplicate email
- if no duplicate found, copy form to a sesion var and
cflocate to next
page; if duplicate found show error to user
- on next page display user-submitted data from the session
var
make sure session vars are enabled in cf administrator and
sessionmanagement is enabled in your appliction.cfm/cfc

Bizarre CFIF issue with dynamic form variables? Very strange...

I can't figure out what I'm doing wrong here. Here's my code. Issue explained below.
            <cfquery name="reviewconfigloader" datasource="MOLMS">
            SELECT *
            FROM dbo.BaseModel

What I'm doing here is fairly basic.I'm running a query with a number of configs in it...and then creating a loop to output them. Ultimately, I only want the configurations that didnt have 0 submitted in the form on the previous page. Each one of the configs in the config query has a dynamic form variable on the previous page with a quantity tied to it. I am trying to eliminate all quantities past that aren't 0 (or not eliminate, just not show)...as you can see from the cfif statement.
Here's where it gets weird. You'll notice I output #form['baseconfig#reviewconfigloader.basemodelID#']#, just for testing, which shows me the quantity as it should. I ran a test and put in a couple of 1s, 0s, 12s, 6s, etc in the form fields on the previous page. If this thing worked, it wouldnt show anything for any of the records with their basemodelID value being submitted as 0. Not the case. It shows all records. What is more hilarious is that it outputs perfectly in my test #form['baseconfig#reviewconfigloader.basemodelID#']#, showing the correct numbers entered in the previous form, the 1s, the 0s, etc, tied to each record. But for whatever reason, the cfif code isn't catching it.
What's even more bizarre...I replaced the cfif ("form.baseconfig#reviewconfigloader.basemodelID#") NEQ 0 with GT 12 (12 was the highest number that I put in the form) and it still showed all records. Then I put it in as LT 12 and it showed nothing. I decided to take it one step further and put it in for GT 1231243242343 (random massive number), which it still showed all of the records. So somehow, my CFIF statement thinks that ("form.baseconfig#reviewconfigloader.basemodelID#") is a incredibly large number, although when I output it in the row below, it is the number it should be.
I'm stumped. Any ideas? Thanks in advance!!

Hey Dan...thanks....unfortunately...with the cfif testing, thats kinda what I'm
doing because I dont have an "expected" value. My expected value is anything a user inputs thats greater than zero, hence NEQ 0 and NEQ "". The real problem is taht what I'm outputting works and what the cfif clause is seeing is obviously very different.
As far as your comment about looping out the variables and then setting a query equal to the value in a cfquery, remember...these are form objects and therefore nothing can be tied back to the database. The result from the code is establishing a form variable (example.... form.basemodel1 (if 1 was the basemodelID from the database query) so it can capture whatever data the user has passed from the previous page in a text input. So that input could have been 23, it could have been 1053.
So really the only way to do it is create a query and loop out the variables.... and attach them to form objects (basemodel1, basemodel2, basemodel3 etc where the 1,2 and 3 are the unique ID's for those models in the database), and then look for where those form objects may have been filled in in the previous page by stating IF this form object not equal to 0 or "", output the data.
Does that make sense? Thanks for the help guys I'm completely stumped by this. I've done this a million times with CFIF and I'm really struggling with why this isnt working....

Why can I not create a PHP Form Variable binding in Dreamweaver CS6?

I'm using Dreamweaver CS6 on Windows 7.
Currently, I'm following along with Lynda.com tutorial:
Dreamweaver with PHP and MySQL: Ch. 6. Building Data Entry Forms | Handling form submissions with PHP
I'm attempting to add a form variable binding to a PHP document, but after each time I open the menu, type in my name and press OK, it does not show up in my Bindings box.
and then POOF:
Can anyone tell me what I'm doing wrong here? Or what I haven't done yet?
I haven't had a problem with the entire tutorial up until this point and I couldn't find any documentation anywhere else on how to fix my problem.

Using Form Variables in a Formatted Search

Hi everyone, I'm relatively new to SAP B1 and just trying to get some info. I have created a few formatted searches, but I am having trouble with this one in particular.
I am trying to get the 'Business Partner Type' Field under Business Partner Master Data (BP Type, [Form=134 Item=40 Pane=0 Variable=1 OCRD,CardType] to change the user defined fields category displayed [Form=-134 Item=9 Pane=0 Variable=62]
For example, when CardType is Vendor ('S' value), I'd like the user defined fields category 'vendor'( '1' value) to show
Here is my query
SELECT CASE
WHEN $[$40.0.1]='S' THEN '0'
ELSE WHEN $[$40.0.1]='C' THEN '1' END
Which is then assigned as a formatted search to that field.
I was trying to find some sort of definitive guide on form variables and formatted search queries; if anyone can point me in the right direction, I'd appreciate it (I have seen the $[$x.y.z] variables but I am not 100% sure on their usage).
Thanks in advance

Hi,
Try this:
SELECT CASE $[OCRD.CardType\]
WHEN 'S' THEN '0'
WHEN 'C' THEN '1'
END
Please also response for your previous open thread. You may just close it if you do not like the answer.
Thanks,
Gordon
