I have noticed that all the 'successful controls' are listed in the
_GET array or the _POST array ! But their type is unknown. From here I can
scan and generate my sql update statement!

This might be worth a try, but as you say non-standard. In the tests I
have done, PHP (or maybe it's rather the user agent!?) puts the controls
in corresponding variables in the order they are listed in the form. And
what happens to the value when the user toggles the checkbox ?
