Code

function filefield_validate_file_widget_support($file, $field, $field_widget, $supported_file_widgets) {
  $errors = array();

  // No widgets at all means the widget settings db entry does not exist,
  // so we fall back to "accept this file and use the generic edit widget".
  if (empty($field_widget['file_widgets'])) {
    return $errors;
  }

  // In the common case, we only accept a file if an enabled widget
  // wants to handle it.
  $edit_widget_info = filefield_widget_for_file($file, $field, $field_widget);
  if (empty($edit_widget_info)) {
    $errors[] = t('Uploaded files are restricted to the following categories: !widgets.', array(
      '!widgets' => implode(', ', $supported_file_widgets),
    ));
