How to echo field names and values?

"Hi, how do we show the fields that were submitted to a form after it has been submitted? For example, we have a new form. We want to have the user fill it out. Then after it is submitted, echo the field names and values to the page when it says the form was submitted correctly (displayed like the email we receive). We only want to do this with ONE form on our site, NOT ALL forms. So a general template edit probably won't work.

Any help would be great.
