public function ParagraphsWidget::massageFormValues in Paragraphs 8

Massages the form values into the format expected for field values.

Parameters

array $values: The submitted form values produced by the widget.

• If the widget does not manage multiple values itself, the array holds the values generated by the multiple copies of the $element generated by the formElement() method, keyed by delta.
• If the widget manages multiple values, the array holds the values of the form element generated by the formElement() method.

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 of field values, keyed by delta.
