Description: 

The field definition methods provided by the Entity Manager have gradually replaced the FieldInfo service that provided field information for configurable fields only.

The changes in #2116363: Unified repository of field definitions (cache + API) completed that conversion and provided the final pieces to deprecate and remove the FieldInfo service.

API changes

  • FieldInfo::getFieldMap() -> EntityManager::getFieldMap()
  • field_info_field($entity_type, $field_name) -> FieldStorageConfig::loadByName($entity_type, $field_name)Only for cases where the code is explicitly working with configurable fields, see node_add_body_field() as an example.
  • field_info_instance($entity_type, $field_name, $bundle) -> FieldConfig::loadByName($entity_type, $bundle, $field_name).
    Only for cases where the code is explicitly working with configurable fields, see node_add_body_field() as an example. Note the different order of arguments.

When working directly with an $entity, the field definitions (which include base and configurable fields) can be directly requested from the object with $entity->getFieldDefinitions() or $entity->getFieldDefinition($field_name). In case an entity object is not available, the EntityManager provides the methods getFieldDefinitions($entity_type, $bundle) getFieldStorageDefinitions($entity_type).

I can't see how to do the equivalent of field_info_instances() and field_info_fields() ?
getFieldStorageDefinitions($entity_type_id) works for content entity types but how do I get the content entity types?
Could it be that the FieldInfo conversion is not actually complete?

What do you want to do?

fields and instances are always by entity_type now, so you need them anyway. If you want a list of all fields/instances, you can use the field map, and if you just want configurable fields, you can just load field/instance config entities.

FYI , this is how to load the "field map"

/** @var EntityFieldManagerInterface $entity_field_manager */
$entity_field_manager = \Drupal::service('entity_field.manager');
$field_map = $entity_field_manager->getFieldMap();

For load filed:

$field_config = \Drupal\field\Entity\FieldStorageConfig::loadByName('node', 'field_machine_name');

To get more settings like list of allowed values for drop-down:

$field_config_allowed_values = $field_ua_aaa_content_status->getSettings()['allowed_values'];
