yep, real easy.

1. create two forms: simply clone your default form
2. one the first form:
   1. strip form to only include the fields you want (name etc)
   2. configure the FORM ACTION setting to point to the page that contains form #2
   3. add first form to the sidebar
      1. adjust CSS for this specific form (width etc.)
3. second (complete) form:
   1. add second form to a page and copy permalink (used for above FORM ACTION)

done.

the second form should (since some of the fields have the same name!) take over the initially provided data.

Got URLs ?

Sorry forgot to mention that of course the field IDs have to match.

E.g. for "Your Full Name", enter "Your Full Name[id:full_name]" in both your forms

…and make sure to enable CUSTOM ID/NAMES for form fields in each config.

Is it possible to do this without using the first form from the sidebar? I am trying to make this work using 2 pages but something is not working and I am not sure if it is a problem with my forms or a problem with cforms in general. Here is what I have:

Form #1

fields: name, email

enabled id's and added them fields

submit form data to: Page #2 permalink

Form #2

fields: name, email, comments

enabled id's and added to fields as above

In essense the form #2 is a clone of form #1 with an extra field and the submit form data part removed.

Page #1

contains form #1

Page #2

contains form #2

When I goto page #1 I see form #1 and the id's are correct. The form submission sends to the correct permalink to page #2 but when it tries to load the permalink it gives me a 404 error. If I go directly to page #2 using the same permalink it shows me form #2.

Any ideas what may be the problem? I am using the latest version of cforms and version 2.6.1 of wordpress.

Hi there. I'm trying to work this solution on my site for some forms, but can't seem to get the field values to pass along. I've read in places that sometimes wordpress' .htacess rewrite rules can mess with data not getting passed on with the action="POST". Could this be happening, and if so, is there a workaround?

I set up a testform here.

The second page is here.

In the first page and second, I used the [id:form_name] format to give custom ID names, as well as enabling that function in the admin. Then I checked the "enable form action" box and redirected to the second page.

Any obvious thing I"m missing for why this won't work? Thanks!

Thanks for the info. 

I would be interested in the beta test, but at very least will get things upgraded to the current version soon.
