[Typo3-german] php formmailer

[Matthias Waldmüller]

hi,
i have a quick question.

is it possible to add a php formmailer that calls itself to typo3?
i added it with the Page PHP Content plugin and the first page shows correctly.
but when i hit the preview button all fields are cleared and the first page displays again.
for the forms action tag i entered index.php?id=39.

thanx in advance
