html form re-check

I was wondering if anyone has any opinion on the best way to handle the following scenario.

I have a form and I'd like the form to return a page that says something like. Here is what you submitted, are you sure this is correct? Yes/No

Hi,

I don't know if your ISP has PHP installed, but that's the easiest way to transfer the data from a form to a next page.

If not, one solution is to use multiple frames and transfer the data to a 1 pixel frame with hidden formfields and again transfer this to the 'message'-page.

But why don't you use a simple javascript confirm-popup to present the data before the form is sent?
