public function FlexiformEntityFormDisplay::extractFormValues in Flexiform 8

Extracts field values from the submitted widget values into the entity.

This accounts for drag-and-drop reordering of field values, and filtering of empty values.

Parameters

\Drupal\Core\Entity\FieldableEntityInterface $entity: The entity.

array $form: The form structure where field elements are attached to. This might be a full form structure, or a sub-element of a larger form.

\Drupal\Core\Form\FormStateInterface $form_state: The form state.

Return value

array An array whose keys and values are the keys of the top-level entries in $form_state->getValues() that have been processed. The remaining entries, if any, do not correspond to widgets and should be extracted manually by the caller if needed.
