Drupal 8: delete all nodes of the same type

Question

I have a need to remove all nodes of the same type in Drupal 8 (there are over 7k of nodes).

It wouldn\'t be a problem for Drupal 7 (DB query + node_del

Answer 1

The entity_delete_multiple is deprecated as of Drupal 8.0.x, will be removed before Drupal 9.0.0. Use the entity storage's delete() method to delete multiple entities:

// query all entities you want for example taxonomy term from tags vocabulary
$query = \Drupal::entityQuery('taxonomy_term');
$query->condition('vid', 'tags');
$tids = $query->execute();

$storage_handler = \Drupal::entityTypeManager()->getStorage($entity_type);
$entities = $storage_handler->loadMultiple($tids);
$storage_handler->delete($entities);

Answer 2

I use Drupal console for this https://docs.drupalconsole.com/ko/commands/entity-delete.html

drupal entity:delete [arguments]

Answer 3

Drupal 8 has the functionality to get nodes by content type, so I would use

$nodes = \Drupal::entityTypeManager()
    ->getStorage('node')
    ->loadByProperties(array('type' => 'your_content_type'));

foreach ($nodes as $node) {
    $node->delete();
}

Answer 4

For Drupal 9.0 works fine

  $ids = \Drupal::entityQuery('node')
    ->condition('type', 'article')
    ->execute();

  $storage_handler = \Drupal::entityTypeManager()->getStorage("node");
  $entities = $storage_handler->loadMultiple($ids);
  $storage_handler->delete($entities);

Answer 5

To delete all entities of some entity types, i use this snippet adapted from last comment:

$entity_types = ['taxonomy_term','node','menu_link_content',];
foreach ($entity_types as $entity_type) {
  $query = \Drupal::entityQuery($entity_type);
  $ids = $query->execute();

  $storage_handler = \Drupal::entityTypeManager()->getStorage($entity_type);
  $entities = $storage_handler->loadMultiple($ids);
  $storage_handler->delete($entities);
}

The very easy way is to install Bulk Delete module. It's available for D7 & D8.

After installing the module, you will see the Bulk Delete node tab option when you click on content menu.

It saved my day :)

For your ease, I have attached a screenshot.
