How to get all values from a new node being created in hook_ENTITY_TYPE_presave()

Question

Drupal 8.7.2

function mymodule_node_presave(Drupal\Core\Entity\EntityInterface $entity) {
  data_dump($entity->original); //is empty because its a new node, not a node being updated.
  // How to get all values at one time?
  // By values I mean the same value you would get from:
  data_dump($entity->get('title')->value);
  // but from all fields and not just one field at a time.
}

I have a custom content type that has 30 custom fields that I need to examine inside this hook. I'd like to avoid getting the value of each field individually.

Thank you for your time.

Answer 1

There are probably a few different ways to get that info, but if the returned format suits your needs then EntityInterface::toArray(), which Gets an array of all property values, is probably the most succinct:

$field_data = $entity->toArray();

Answer 2

You can try use Content Entity Field definitions

Sample code:

foreach ($entity->getFieldDefinitions() as $field => $definition) {
    $entity->get($field)->getValue()
}
