function hook_node_update

Respond to updates to a node.

This hook is invoked from node_save() after the database query that will update node in the node table is scheduled for execution, after the type-specific hook_update() is invoked, and after field_attach_update() is called.

Note that when this hook is invoked, the changes have not yet been written to the database, because a database transaction is still in progress. The transaction is not finalized until the save operation is entirely completed and node_save() goes out of scope. You should not rely on data in the database at this time as it is not updated yet. You should also note that any write/update database queries executed from this hook are also not committed immediately. Check node_save() and db_transaction() for more info.


$node: The node that is being updated.
