Try changing your form declaration from this:

<form action="" enctype="multipart/form-data" method="post">

to this:

<form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?>" enctype="multipart/form-data" method="post">

Move the php code to the top of index.php. You're doing things before anything should be outputted. If index.php outputs anything before this runs, it fails.
