Code

function themekey_ui_node_author2theme($nid) {
  $custom_theme =& drupal_static('themekey_custom_theme', '');

  // node_load() must not be called from hook_init().
  // Therefore, we have to execute SQL here.
  $query = db_select('node', 'n')
    ->fields('tuat', array(
    'theme',
  ))
    ->condition('n.nid', $nid);
  $query
    ->join('themekey_ui_author_theme', 'tuat', 'n.uid = tuat.uid');
  if ($theme = $query
    ->execute()
    ->fetchField()) {
    if ('default' != $theme && themekey_check_theme_enabled($theme)) {
      $custom_theme = $theme;
      return 'static';
