Need help detecting attached files

Hi, I'm using a mailer class that allows for external file attachments. I was using the test: if ($HTTP_POST_FILES[$val]['size']) { Which worked fine. However, I wanted something more generic that works for POST or GET so I wrote the following code: $request = 'HTTP_' . getenv('REQUEST_METHOD') . '_VARS'; global $$request; if ($$request[$val]['size']) { However, it is always failing the test and therefore not working. Any ideas? Thanks, Don --- Outgoing mail is certified Virus Free.
