This is an example to demonstrate how to make a Drupal node support file uploads.

Code

function fileupload_validate(&$node) {
  // Check for a new file upload.
  if ($file = file_check_upload('file')) {
    $node->file = $file;
  }

  // Make sure there is an upload or an existing file.
  if (!$file && !file_exists($node->current_file)) {
    form_set_error('file', t('A file must be provided.'));
  }
}
