Code
function comment_entity_predelete(EntityInterface $entity) { // Entities can have non-numeric IDs, but {comment} and // {comment_entity_statistics} tables have integer columns for entity ID, and // PostgreSQL throws exceptions if you attempt query conditions with // mismatched types. So, we need to verify that the ID is numeric (even for an // entity type that has an integer ID, $entity->id() might be a string // containing a number), and then cast it to an integer when querying. if ($entity instanceof FieldableEntityInterface && is_numeric($entity->id())) { $entity_query = \Drupal::entityQuery('comment'); $entity_query->condition('entity_id', (int) $entity->id()); $entity_query->condition('entity_type', $entity->getEntityTypeId()); $cids = $entity_query->execute(); entity_delete_multiple('comment', $cids); \Drupal::service('comment.statistics')->delete($entity); } }
