4. 11.x core/modules/user/user.api.php \hook_user_cancel()

Act on user account cancellations.

This hook is invoked from user_cancel() before a user account is canceled. Depending on the account cancellation method, the module should either do nothing, unpublish content, or anonymize content. See user_cancel_methods() for the list of default account cancellation methods provided by User module. Modules may add further methods via hook_user_cancel_methods_alter().

This hook is NOT invoked for the 'user_cancel_delete' account cancellation method. To react to that method, implement hook_ENTITY_TYPE_predelete() or hook_ENTITY_TYPE_delete() for user entities instead.

Expensive operations should be added to the global account cancellation batch by using batch_set().

Parameters

array $edit: The array of form values submitted by the user.

\Drupal\user\UserInterface $account: The user object on which the operation is being performed.

string $method: The account cancellation method.
