Gæstebog i HTML_QuickForm med mulighed for preview!

Hej eksperter

Jeg har postet nedenstående i PEAR nyhedsgruppen, men det er jo også en mulighed at nogen her er i stand til at hjælpe! Jeg gider ikke oversætte det fra engelsk til dansk, da det nok ikke gør nogen nævneværdig forskel for folk.

--------------------------------------------------------
I'm using QuickForm for a Guestbook application at my website. It has support for graphical smilies in the sense that the text-smilies in the message is converted to graphical smilies when viewing the message normally. I would like to be able to offer the user a preview of his/her message before finally submitting the message!

All in all something like the follwing functionality:

if !form_validate
  show_form with "Preview message" and "Submit message" submit buttons
else
  if preview
    show preview of the message with "Modify message" and "Submit message" buttons
  else
    process message
  endif
endif

And the following connections between the different states:

"Normal Form" -> "Preview Message" (Through Preview)
"Normal Form" -> "Submit Form"  (Through Submit)

"Preview Message" -> "Normal Form" (Through Modify)
"Preview Message" -> "Submit Form" (Through Submit)

"Submit Form" -> "Processing" (If validated!)

I'm looking for ideas on how to present a preview and being able to go back to the form to modify the message - I have an idea that "freeze()" might help me in this regard, but I haven't used it before!
