3. 11.x core/lib/Drupal/Core/Entity/entity.api.php \hook_entity_extra_field_info()

Exposes "pseudo-field" components on content entities.

Field UI's "Manage fields" and "Manage display" pages let users re-order fields, but also non-field components. For nodes, these include elements exposed by modules through hook_form_alter(), for instance.

Content entities or modules that want to have their components supported should expose them using this hook. The user-defined settings (weight, visible) are automatically applied when entities or entity forms are rendered.

Return value

array The array structure is identical to that of the return value of \Drupal\Core\Entity\EntityFieldManagerInterface::getExtraFields().
