How could I use the same class to download the file uploaded previously? I would appreciate any help. Thank you, Flávio.

if (isUploaded) {
$adapter->addFilter('Rename', $myownname);
if (isValid) {
$adapter->receive();
} else {
print "Oops";
}
}

I'm really new to Zend Framework so I'd love if you could correct me, but I want to rename the file with a unique id number, but I can only create that unique ID number after the file has uploaded and and the move filter has been triggered? Or could I set the filter after isuploaded() but before receive()? Its kind of a chicken and the egg thing, unless I'm missing something though.

Wouldn't it be better to use the Rename Filter instead of extending the form element ? ;-) Greetings Thomas @Zach:

Its pretty obvious that this element is fairly new, because its really a major security flaw to not have anything in place to easily rename the uploaded file based on critera like a userid or a pictureid. You can set it to not overwrite an existing file, at least closing the hole of your admin's profile getting overwritten with goatse, but that also makes it quite hard to upload generic sounding files (how many people might name a file profile.jpg? I'm guessing more than one on the entire internet) or even impossible in a situation where you're collecting the same exact file from people ("Upload config.ini here please.") Right now the only way I can see to do this cleanly would be to massively extend the file element, and have my own functions for recieve etc in my class that take an id or something. The only other thing I could think of was do an if(isuploaded) and then go in and setdestination() after doing whatever needs to be done to make it a unique filename.
