Tim,
Try this for upload.php:
CODE
<?php
error_log(print_r($_FILES, 1), 3, "/tmp/upload.log");
?>
After uploading, check to see if there are any results in "/tmp/upload.log".
Also, is uploading enabled on your PHP installation? Some php config vars to check:
CODE
; Whether to allow HTTP file uploads.
file_uploads = On
; Maximum allowed size for uploaded files.
upload_max_filesize = 2M
Let us know if you get it working,
Steve Spencer
