[TYPO3-dev] Show or hide flexform field in subject to admin account

[Patrick Lobacher]

Hi everybody,

I try to present an input field in a flexform in subject to the admin 
account.

If the BE_USER isAdmin the field should be display (and processed) and 
if not, the user should not even see this field (or the coresponding 
value should be deleted on the way to the database).

Now the question:

- I know that this is possible with "dynaflex", but I don't want the 
user of my extension to install another extension just for this simple task

- Is it possible to hide/show the field with some hook? Which one is the 
correct one? getMainFields_preProcess in class.t3lib_tceforms.php?

- Is there another (simple) solution?


Thanks in advance,
Patrick
