You can't access it before the upload - how would the server know what type of file it was if it wasn't uploaded to it first?!

Bottom of that page shows you how to access it after the upload.

There is a function build in PHP5.
Code:
$nombre = pathinfo($_FILES['img_principal']['name']);
echo $nombre['extension'];This givs you the file extension, to!
