function hook_delete

Respond to node deletion.

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_delete() to respond to node deletion of all node types.

This hook is invoked from node_delete_multiple() before hook_node_delete() is invoked and before field_attach_delete() 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 delete operation is entirely completed and node_delete_multiple() 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_delete_multiple() and db_transaction() for more info.


$node: The node that is being deleted.
