Code

function taxonomy_link($type, $node = NULL) {
  if ($type == 'taxonomy terms' && $node != NULL) {
    $links = array();

    // If previewing, the terms must be converted to objects first.
    if (isset($node->build_mode) && $node->build_mode == NODE_BUILD_PREVIEW) {
      $node->taxonomy = taxonomy_preview_terms($node);
    }
    if (!empty($node->taxonomy)) {
      foreach ($node->taxonomy as $term) {

        // During preview the free tagging terms are in an array unlike the
        // other terms which are objects. So we have to check if a $term
        // is an object or not.
        if (is_object($term)) {
          $links['taxonomy_term_' . $term->tid] = array(
