public function AutosaveFormBuilder::processForm in Autosave Form 8

Processes a form submission.

This function is the heart of form API. The form gets built, validated and in appropriate cases, submitted and rebuilt.

Parameters

string $form_id: The unique string identifying the current form.

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

\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form. This includes the current persistent storage data for the form, and any data passed along by earlier steps when displaying a multi-step form. Additional information, like the sanitized \Drupal::request()->request data, is also accumulated here.
