1. 11.x core/lib/Drupal/Core/Render/Element/ComponentElement.php \Drupal\Core\Render\Element\ComponentElement::valueCallback()

Returns NULL to let the Form API fall back to #default_value or #value. Components delegate actual value rendering to the Twig template via the form_state prop, so no server-side value transformation is needed here.

Parameters

array $element: An associative array containing the properties of the element.

mixed $input: The incoming input to populate the form element. If this is FALSE, the element's default value should be returned.

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

Return value

mixed The value to assign to the element.

Overrides FormElementInterface::valueCallback
