I have created class content type and set Allowed number of values to unlimited" to "Division" field Now I want to get "Division" field values programmatically in node presave hook I'm using below code.

function example_node_presave(Drupal\Core\Entity\EntityInterface $node){
  if($node->bundle() == "class") {
     $getDivison = $node->get('field_class_division')->target_id;
   }
}

If i print $getDivison then I get 739 only. Division field

You can loop over a field object and access each item separately, that's often more convenient than going through getValue():

function example_node_presave(Drupal\Core\Entity\EntityInterface $node){

  if($node->bundle() == "class") {
     foreach ($node->get('field_class_division') as $item) {
       echo $item->target_id;
     }
   }
}

And to access a specific delta (that's what the index in a multi-value field is called in the Field API), you can access it like an array as well, but you need to make sure that the deltas exist:

echo $node->get('field_class_division')[1]->target_id

See https://wizzlern.nl/drupal/drupal-8-entity-cheat-sheet for a very useful cheat sheet on how to work with the Entity Field API.

You can use:

function example_node_presave(Drupal\Core\Entity\EntityInterface $node){

  if($node->bundle() == "class") {
     // Use getValue() to get multiple values in array.
     $getDivison = $node->get('field_class_division')->getValue();
   }
}

  • yeah, it's the perfect answer, you just need to run a foreach loop the $getDivison variable, you could easily fetch the individual value.
