Extends Drupal file entities to be fieldable and viewable.

Code

function path_file_update($file) {
  if (isset($file->path)) {
    $path = $file->path;
    $path['alias'] = trim($path['alias']);
    // Delete old alias if user erased it.
    if (!empty($path['fid']) && empty($path['alias'])) {
      path_delete($path['fid']);
    }
    // Only save a non-empty alias.
    if (!empty($path['alias'])) {
      // Ensure fields for programmatic executions.
      $path['source'] = 'file/' . $file->fid;
      // Core does not provide a way to store the file language but contrib
      // modules can do it so we need to take this into account.
      $langcode = entity_language('file', $file);
      $path['language'] = !empty($langcode) ? $langcode : LANGUAGE_NONE;
      path_save($path);
    }
  }
