I want to retrieve all fields that entities are using (including locked fields).

How can I get a list of fields that are used in entities?

Like we get in admin/reports/fields.

  • Do you want to do this programmatically, or review a site's use of fields through the UI? – autopoietic Aug 10 '16 at 8:05

I would recommend EntityFieldManager::getFieldMap. The EntityManager is only a service to provide functions from other classes.

From documentation:

Return value

array An array keyed by entity type. Each value is an array which keys are field names and value is an array with two entries:

  • type: The field type.
  • bundles: An associative array of the bundles in which the field appears, where the keys and values are both the bundle's machine name.

EntityFieldManagerInterface::getFieldMap() produces a keyed array by entity type > field name with further information on the field type and its associated bundles.

$field_map = \Drupal::entityManager()->getFieldMap();
$node_field_map = $field_map['node'];
$node_fields = array_keys($node_field_map['node']);

There's also EntityFieldManagerInterface::getFieldDefinitions() if you want further field metadata. It produces an array of BaseFieldDefinition & FieldConfig objects that you can parse through for further detail.

  $node_article_fields  =\Drupal::entityManager()->getFieldDefinitions('node','article');

  • Thanks Shawn, I am not getting fields like they listed in above image. Below field's i am getting: comment, contact_message, file, node, shortcut, taxonomy_term, user, menu_link_content – Ajay Reddy Aug 10 '16 at 9:30
  • There was a typo with the code. As mentioned with the answer, the function produces a keyed array that contains entities, field names, then field details. – Shawn Conn Aug 10 '16 at 14:41

field_info_instance() would do what you want, though if you look in the docs you will see that in D8 it is deprecated in favour of

Field::fieldInfo()->getBundleInstance($entity_type, $bundle, $field_name).
