hook_update

Respond to updates to a node.

This hook is invoked only on the module that defines the node's content type (use hook_node_update() to act on all node updates).

This hook is invoked from node_save() after the node is updated in the node table in the database, before field_attach_update() is called, and before hook_node_update() is invoked.

Parameters

Drupal\node\Node $node: The node that is being updated.
