How to delete all Taxonomy terms of particular vocabulary using entity_delete_multiple?

Question

I want to delete all taxonomy terms of particular vocabulary using entity_delete_multiple. For node it is working fine

$result = \Drupal::entityQuery('node')
      ->condition('type', 'page')
      ->execute();
  entity_delete_multiple('node', $result);

If i am changing taxonomy_term and type to tags or any other vocabulary, or replaced type by bundle

$result = \Drupal::entityQuery('taxonomy_term')
      ->condition('type', 'tags')
      ->execute();
  entity_delete_multiple('taxonomy_term', $result);

it is throwing error like this.

Drupal\Core\Entity\Query\QueryException: 'type' not found in Drupal\Core\Entity\Query\Sql\Tables->ensureEntityTable() (line 304 of core/lib/Drupal/Core/Entity/Query/Sql/Tables.php).

And also i need a same query to delete user(s), watchdog and profiles.

Is there any way to do it?

Answer 1

Try to use vid instead of type. I haven't tried the code, but try the following

$result = \Drupal::entityQuery('taxonomy_term')
      ->condition('vid', 'tags')
      ->execute();
  entity_delete_multiple('taxonomy_term', $result);

Here is a good example for using entityQuery.

For deleting users, you can use entity_delete_multiple or user_delete_multiple

To delete user with uid 10

entity_delete_multiple('user', \Drupal::entityQuery('user')->condition('uid', '10', '=')->execute());

or pass an array of uids to user_delete_multiple

user_delete_multiple(array $uids);

I'm not aware of how to delete comments.

For taxonomy use vid:

$result = \Drupal::entityQuery('taxonomy_term')
      ->condition('vid', 'tags')
      ->execute();

Which is the bundle of taxonomy.

Answer 3

I know the question specifically asks about entity_delete_multiple, but the function is deprecated, scheduled to be removed "before" Drupal 9. Here's a version without entity_delete_multiple

/**
 * Delete all taxonomy terms from a vocabulary
 * @param $vid
 */
function delete_terms_from_vocab($vid) {

  $tids = Drupal::entityQuery('taxonomy_term')
    ->condition('vid', $vid)
    ->execute();

  if (empty($tids)) {
    return;
  }

  $term_storage = \Drupal::entityTypeManager()
    ->getStorage('taxonomy_term');
  $entities = $term_storage->loadMultiple($tids);

  $term_storage->delete($entities);
}

Answer 4

For delete all taxonomy terms of particular vocabulary.

Try

 $vid = 'name_of_the_vocabulary';
      $tids = \Drupal::entityQuery('taxonomy_term')
          ->condition('vid', $vid)
          ->execute();
      entity_delete_multiple('taxonomy_term', $tids);

You can try below code,which works for me

 $vids = Vocabulary::loadMultiple();
    foreach ($vids as $vid) {
      if ($vid->label() == 'YourVocab') {
        $container = \Drupal::getContainer();
        $terms = $container->get('entity.manager')->getStorage('taxonomy_term')->loadTree($vid->id());
        if (!empty($terms)) {
          entity_delete_multiple('taxonomy_term', $terms);
        }
        break;
      }
}
