function FormBuilderInterface::prepareForm

Prepares a structured form array.

Adds required elements, executes any hook_form_alter functions, and optionally inserts a validation token to prevent tampering.

Parameters

string $form_id: A unique string identifying the form for validation, submission, theming, and hook_form_alter functions.

array $form: An associative array containing the structure of the form.

\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form. Passed in here so that hook_form_alter() calls can use it, as well.
