[Typo3] saving formdata

[Gregor Spengler]

Hi,

i wrote an extension using the kickstarter. The extension should save
data posted by a form displayed by the extention. The data has to be
extended by the extension, so a extra save method is implemented.

Now the problem is, that everytime the form is submitted without a valid
uid for the data two records are created in the table used for the
extension.

Looking for a solution, a formfield named "doNotSave" was mentioned. But
even after creating a hidden formfield with the name "doNotSave" in the
html-Template there were two records created.

Now there are a few questions:

1. How do I tell Typo3 not to save the formdata not at all.

2. If there is no way of stopping typo3 from saving the data, how do I
pass the the extra form data to typo3 in a save way.

sincerely
