function taxonomy_entity_query_alter in Drupal 7

Implements hook_entity_query_alter().

Converts EntityFieldQuery instances on taxonomy terms that have an entity condition on term bundles (vocabulary machine names). Since the vocabulary machine name is not present in the {taxonomy_term_data} table itself, we have to convert the bundle condition into a property condition of vocabulary IDs to match against {taxonomy_term_data}.vid.

Code

function taxonomy_entity_query_alter($query) {
  $conditions =& $query->entityConditions;

  // Alter only taxonomy term queries with bundle conditions.
  if (isset($conditions['entity_type']) && $conditions['entity_type']['value'] == 'taxonomy_term' && isset($conditions['bundle'])) {

    // Convert vocabulary machine names to vocabulary IDs.
    $vocabulary_data = taxonomy_vocabulary_get_names();
    $vids = array();
    if (is_array($conditions['bundle']['value'])) {
      foreach ($conditions['bundle']['value'] as $vocabulary_machine_name) {
        $vids[] = $vocabulary_data[$vocabulary_machine_name]->vid;
      }
    }
    else {
      $vocabulary_machine_name = $conditions['bundle']['value'];
      $vids = $vocabulary_data[$vocabulary_machine_name]->vid;
    }
    $query
      ->propertyCondition('vid', $vids, $conditions['bundle']['operator']);
    unset($conditions['bundle']);
  }
