How do I access a field value for an entity (e.g. node) object?

Question

node_load((int) $nid) loads a fully-populated node entity. $node->title->value gets the title, but how do I access field values in Drupal 8?

Answer 1

I guess you do not need to convert $entity into an array, this would simply work.

$entity->get('field_name')->getValue();

Alternatively, we can make it easier to read as follows:

$entity->field_name->value;

FYI : Using kint() from the devel_kint module will let you know all the available methods that could be used to access the object elements, so comparatively var_dump() is less helpful.

Answer 2

in drupal 8 , $node being of class node

 $node->field_machine_name->getValue();

or

$node->get('field_machine_name')->getValue();

will return an array of values.

If you expect only one, you might as well stringify the array with

$node->field_machine_name->getString();

or

 $node->get('field_machine_name')->getString();

Answer 3

For fields you should be able to use $node->body->value for example. If you don't know what the field names are I recommend installing the Devel module for Drupal 8 and inspecting the node via like dsm($node).

Answer 4

You can always do $entity->toArray() to see what's in an entity. Even when using xdebug (for example with phpstorm) making sense of an entity object on its own is very hard. I doubt dsm($node) in Drupal 8 makes any sense. If you insist on in-browser debugging (but you shouldn't, Drupal 8 is too complex to debug without xdebug) dsm($node->toArray()) is what you want.

Answer 5

Use following code snippet to get node field values

This is used to get node id from url

$nid = \Drupal::routeMatch()->getRawParameter($node_id);

To load node data using nid

$node = \Drupal::entityTypeManager()->getStorage('node')->load($nid);

This is used to get field value.

$terms = $node->get('field_Name')->getValue();  

This is used to get node title.

$product_name = $node->getTitle();

Answer 6

It's simply:

$node->get('field_name')->getValue();

If the field is an entity reference field, there are some special ways to get the referenced entities.

To get the target id (first element):

$entity->get('field_entity_reference')->target_id;

To get the loaded entity (first element):

$entity->get('field_entity_reference')->entity;

When using ->entity on the field it automatically returns the loaded entity.

If the field can contain multiple references, you can fetch them all like this:

$entities = $entity->get('field_entity_reference')->referencedEntities();

That will return an array of entities.

Answer 7

For me, having an $entity (a node) this worked:

$entity->field_name->getValue();

using 8.1.

Answer 8

While using (the actual correct way):

$node = \Drupal\node\Entity\Node::load($nid);
$node->get('nid')->value; // returns a raw value - Node ID

// Following both returns array structure containing value/target id nested value.
$node->get('nid')->value(); 
$node->nid->getValue();

Answer 9

use Drupal\node\Entity\Node

$node = Node::load($nid);
$title = $node->get('title')->value;

Or

use Drupal\node\Entity\Node

$title = Node::load($nid)->get('title')->value;

Answer 10

When not using nodes but entities (like the OP asked) things get a little more murky. For example when using an address entity it only took me 8 tries to get the organization value.

$v1 = $address->get('field_address_organization')->getString();
$v2 = $address->get('organization')->getString();
$v3 = $address->get('field_organization')->getString();
$v4 = $address->field_organization->getValue();
$v5 = $address->organization->getString();
$v6 = $address->field_organization->getString();
$v7 = $address->organization->getValue();
$v8 = $address->organization;

The only one that didn't throw an exception was the last one. And I'm lying when I say it only took me 8 tries to get the right answer - but 8 is all I'll admit to publicly. :)

Answer 11

I had to get the address entity and render it programmatically. After a lot of searching and debugging, this is what worked best for me

if ($field_name == 'field_address') {
      $render_array = $entity->get($field_name)->view('address_plain');
      $body .= \Drupal::service('renderer')->renderRoot($render_array);
    }

Answer 12

As someone already mentioned you can do something like this to get the value if you have a Drupal DateRange field:

$node->field_date_range->value

That will return the timestamp.

You can also do something like this:

$node->field_date_range->timezone

to get the timezone.
