Implementation of hook_nodeapi().
When a node revision is deleted, we need to remove the corresponding record from our table. The only way to handle revision deletion is by implementing hook_nodeapi().
<?php
function node_example_nodeapi(&$node, $op, $teaser, $page) {
switch ($op) {
case 'delete revision':
// Notice that we're matching a single revision based on the node's vid.
db_query('DELETE FROM {node_example} WHERE vid = %d', $node->vid);
break;
}
}
?>
