function hook_delete
| 7.x node.api.php | hook_delete($node) |
| 6.x node.php | hook_delete(&$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.
