In the hook_entity_update function

update_candidat_from_contrat_direct(Drupal\Core\Entity\EntityInterface $entity)

I call another function in which :

  • I create a new node

       $new_entity = \Drupal::entityTypeManager()->getStorage('node')->create([
        'type' => 'candidat',
        'field_nom' => $nom,
  • I want to attach this $new_entity to the $entity

      $nid = $new_entity->id();
      $candidats_attaches[] = $nid;
      $entity->set('field_candidats', $candidats_attaches);

But because of the call to "save" function, this involve a new call to the "hook_entity_update", so another call to this sub-function, so a loop....

I understood that there is the "presave" function to avoid this behaviour, but I did not succeed to use it. Can I have some advices, please?

  • Welcome to Drupal Answers! Both hook_entity_presave() and hook_entity_update() would be called when $entity->save() is called. hook_entity_presave() doesn't avoid the issue you have with your current code. Is $entity a node, or a different entity? In the case it's a node, is its content type different?

  • Also, the question seems to say that update_candidat_from_contrat_direct(Drupal\Core\Entity\EntityInterface $entity) is an implementation of hook_entity_update() but that's not true.

  • "update_candidat_from_contrat_direct(Drupal\Core\Entity\EntityInterface $entity) " is called by "lamih_entity_update"

  • When entity is updated by the user, the aim is, within update_candidat... function, to, : (1) create an instance ot a content type, (3) fill its fields with values isued from entity form, (3) register id of this instance in a field of the entity, (4) update the entity in the database.
