I''m trying to figure out the best way to tell if a user submitted a file from within a form. The file uploading is optional, meaning they can edit the record in the database but optionally click the button to replace the file (the file is not stored in the db, simply in the filesystem). Really I just need to safely detect if they''ve added the file to that form, before trying to save the file away or anything. What is the best way for me to do this? -raymond
