Pass variables to another page then have the submitHelpful Member!(2)

I have a one web page form that takes Visitor information and works great where it processes the information on the form and sends the information to an email address.

Now I need to add an optional 5 more Visitor entries to my form which I would like to put an optional "next page" so the form is not too long.  How can I pass all my variables from the first page to the next page and have the submit button on the next page?

So at the bottom of my first page will be the original submit button for the first page of visitor information and an option to go to another page to add more visitors so the user can add addtional visitors on the next page.   After filling out the visitors for the second page they can hit the submit button and send the information for all the visitors from the first and second page.

Put this code inside the form on your second page:

<cfif IsDefined("form.frompageone")>
<cfoutput><cfloop index="thisval" list="#form.fieldnames#">
<cfset field=thisval>
<cfset fieldval = evaluate("form.#thisval#")>
<input type="hidden" name="#field#" value="#fieldval#">
</cfloop></cfoutput>

</cfif>
It carries all of the form variables and their values over to hidden fields in the next form.
The submit button on page one has to be named "frompageone". Plus this can't be a self-submitting form because you'd just mulitply the hidden values.

Thanks I have the first parts working where I get to page two as you stated but not sure how to pull up the values on the action page?

First page:

CODE

<form action="formThree.cfm" method="post">
<input type="Text" name="nameOne">
<input type="Text" name="nameTwo">

<input type="Submit" value="frompageone">
</form>
Second Page:

CODE

<form action="theActionpage.cfm" method="post">
<cfif IsDefined("form.frompageone")>
<cfoutput><cfloop index="thisval" list="#form.fieldnames#">
<cfset field="thisval">
<cfset fieldval = evaluate("form.#thisval#")>
<input type="hidden" name="#field#" value="#fieldval#">
</cfloop></cfoutput>
</cfif>
<input type="Text" name="nameThree">
<input type="Submit">
</form>

The action page error message:

An error occurred while evaluating the expression:
#fieldval#
Error near line 11, column 8.


The action page:

CODE

here it is:<br>
<cfoutput>
nameOne = #fieldval#<br>
nameTwo = #fieldval#<br>
nameThree = #nameThree#
</cfoutput>

Please advise.

Try this:

CODE

<cfoutput>
nameOne = #form.nameOne#<br>
nameTwo = #form.nameTwo#<br>
nameThree = #form.nameThree#
</cfoutput>

Hope This Helps!

I tried that and it still gives me the same type of error.

CODE

<cfoutput>
nameOne = #form.nameOne#<br>
nameTwo = #form.nameTwo#<br>
nameThree = #form.nameThree#
</cfoutput>

Any other suggestions?

<cfset field="thisval">
should be
<cfset field = thisval>

when you evaluate the expression the way you have it you're looking for the value of "form.thisval" which doesn't exist so it wouldn't be defined, hence your error.

Good luck.

one thing that may or may not fix the problem is

<cfset field="thisval">
should be
<cfset field=thisval>

Thanks,
I tried as you suggested and it still gives me the same error.

I have also tried many variations of the the output but cant get it to work.

ok, I don't see how
<cfif IsDefined("form.frompageone")>
is ever true if you have
<input type="Submit" value="frompageone">
in the first form.
frompageone needs to be the NAME of the submit button. not the value.

Ok, let's back up and start over.  On your second page (where you want to pass the info from the first form), try using this instead of what you currently have:

CODE

<cfoutput>
  <cfloop list="#form.fieldnames#" index="f">
    <input type="hidden" value="#jsstringformat(FORM[f])#" name="#f#">
  </cfloop>
</cfoutput>
If you view the source of that page, you should see:

CODE

<input type="hidden" name="nameOne" value="Whatever">
<input type="hidden" name="nameTwo"" value="Whatever">
with the values that you entered in on the first form.  Once you submit the second form (to your action page), you should just be able to reference the values from your first form as #Form.nameOne# and #Form.nameTwo#.

Hope This Helps!

Thanks to both of you it now works.

I looked up jsstringformat and it says it returns a string.
But I dont understand the argument FORM[f]
Can someone please explain that part??

Since you're looping through the list of field names from the first form:

CODE

<cfloop list="#form.fieldnames#" index="f">
the cfloop just assigns the form field names an "alias" of "f", so any time during the loop, #f# would produce the field names.

It's just a way of looping through without having to say: Form.nameOne, Form.nameTwo, Form.nameThree...etc...

Hope This Helps!

its another way to acces the "form" scope  similar to if you were going to do a collection loop.

CODE

<cfloop collection="#form#" item="fieldValue">
<cfoutput>
<cfif fieldValue neq "FIELDNAMES">
<tr>
<td>#fieldvalue#</td>
<td><cfif form[fieldValue] eq "">
Empty String                      
<cfelse>#form[fieldValue]#</cfif></td>
</tr>
</cfif>
</cfoutput>
</cfloop>
