function hook_node_predelete

Act before node deletion.

This hook is invoked from entity_delete_multiple() after the type-specific hook_delete() has been invoked, but before hook_entity_predelete() and field_attach_delete() are called, and before the node is removed from the node table in the database.

Parameters

\Drupal\Core\Entity\EntityInterface $node: The node that is about to be deleted.
