Versions

7 hook_delete($node)

Respond to node deletion.

This is a hook used by node modules. It is called to allow the module to take action when a node is being deleted from the database by, for example, deleting information from related tables.

Parameters

&$node The node being deleted.

Return value

None.

To take action when nodes of any type are deleted (not just nodes of the type defined by this module), use hook_nodeapi() instead.

For a detailed usage example, see node_example.module.
