1. 8.0 core/modules/options/options.module \options_allowed_values()

Returns the array of allowed values for a list field.

Parameters

\Drupal\Core\Field\FieldStorageDefinitionInterface $definition: The field storage definition.

\Drupal\Core\Entity\FieldableEntityInterface|NULL $entity: (optional) The specific entity when this function is called from the context of a specific field on a specific entity. This allows custom 'allowed_values_function' callbacks to either restrict the values or customize the labels for particular bundles and entities. NULL when there is not a specific entity available, such as for Views filters.

Return value

array The array of allowed values. Keys of the array are the raw stored values (number or text), values of the array are the display labels.
