Node

On drupal 8 every elements (almost) are an entity, as any entity you can render a node.

For this, You must use hook_entity_delete.



Example :

function mymodule_entity_delete(\Drupal\Core\Entity\EntityInterface $entity) {

  $entity_type = $entity->getEntityTypeId();

  $entity_id = $entity->id();



Update a node:

Example 1 : Update title

$node = \Drupal\node\Entity\Node::load($nid);

$node->setTitle('The new Title')

$node->save();

It is same as normal node creation but must be in format "Y-m-d" (YYYY-MM-DD)

Example:

Methode 1 : Example:

$value = $node->get($field)->value;

$target = $node->get($field)->target_id; // For entity ref

Methode 2 Example:

Example:

$node = \Drupal::routeMatch()->getParameter('node');

if ($node) {

  $nid = $node->id();

}

Programmatically create and translate nodes.

Exemples:

$translation = $entity->getTranslation('de');

Here an example for create node programmatically in Drupal 8
