function hook_update

Respond to updates to a node.

This is a node-type-specific hook, which is invoked only for the node type being affected. See Node API hooks for more information.

Use hook_node_update() to respond to node update of all node types.

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

$node: The node that is being updated.
