I would recommend storing it in the registry, unless you have reasons
to tether it to the controller.
As for editing the form I would recommend creating methods in the form
class that do all of that. For example:
if (!is_null($this->loggedInUser)) {
$form->loggedIn($this->loggedInUser['userId']);
} else {
$form->notLoggedIn();
}
Then in the form class:
public function loggedIn($userId) {
$this->getElement('user_id')->setValue($userId);
$this->removeElement('naam');
$this->removeElement('website');
$this->removeElement('antispam');
}
public function notLoggedIn() {
$this->getElement('user_id')->setValue('');
}
The loggedIn() and notLoggedIn() methods (or whatever you want to call
them) will alter the form for the proper context. Now if you ever need
to make the same change to the form some place else (like when the
form is being processed) it is easily accomplished with a simple
method call. You could also pass $this->loggedInUser to the form class
constructor so that it can determine whether or not the elements naam,
website and antispam should even be created. Or you could extend
populate() so that when the form is being processed you don't need
your controller to determine if the user is logged in. If the user_id
key does not have a null value it will know to call loggedIn() and
then parent::populate().

Have fun or die trying - but try not to actually die.
