And MD5 hash seems kind of excessive, when you could do:
$filename = preg_replace('/[^a-z0-9_\\.]i/', '', $filename);
But whatever makes you happy.

Try using name="file[1]" instead of "file_1" and your life will become

getElementById and muck with what's visible, but your PHP will be
soooo much easier with name="file[1]"
