I am using something like this:

$adapter = $form->getElement('doc')->getTransferAdapter();

if ($adapter->isUploaded('doc') {
...
}

if ($adapter->isUploaded('employee_cv_file') {
...
}

And it works, but some things still bother me.

As far as I can see, both of the file form elements return the same adapter
class. So doing something like this:

Let's say that you have 2 file elements, and on your form you upload only
the 'doc', and not the other one, you will get this:

$adapter1 = $form->doc->getTransferAdapter();
$adapter2 = $form->employee_cv_file->getTransferAdapter();

echo $adapter1->isUploaded(); // returns true
echo $adapter2->isUploaded(); // returns true

but

echo $adapter1->isUploaded('doc'); // returns true
echo $adapter1->isUploaded('emplyee_cv_file'); // returns false (note that
we are still using $adapter1)

I find it strange to fetch the adapter from one element, and use this
adapter for checking two or more elements and having to provide the name of
the element to the isUploaded method.

Maybe it has something to do with the fact that currently we have only one
transfer adapter, and that the file element can support upload of multiple
files, but I still can't wrap my hand around it although my code does what I
want it to do, just not in the way I would like it do it :) (It would be
more natural for me to either fetch the transfer adapter from the form
itself and that to check the isUploaded() method providing the element name,
or the fetch multiple adapters each from his element and to test if the file
was uploaded without providing the name of the element since the adapter is
fetched from the element itself).

Sorry for the lengthy post, but I would really appreciate some code samples
showing the "proper way" to handle file uploading.
