If that's exactly what you're doing in the script, then your syntax isn't
correct.  According to the CGI perldoc:

  $filename = $query->param('uploaded_file');
  $type = $query->uploadInfo($filename)->{'Content-Type'};

No; it would be insecure to let the script pass back a file name be
uploaded.  Conceivably, a script could grab any file from the browsing
host that it wants.

To get around this, after a successful file upload, I've added a CGI
parameter with the same name as the uploaded file field, but with '.upld'
appended; the value is the uploaded file name.  This gets appended to the
display of the form's filefield, so the user knows that the file has been
successfully uploaded.  My form validation method checks for the .upld
field, and if it matches a file uploaded to the server, it accepts an
otherwise empty file upload field.
