This is an example illustrating how to restrict access to nodes based on some criterion associated with the user.

Code

function node_access_example_nodeapi(&$node, $op, $arg = 0) {
  switch ($op) {
    case 'load':
      $node->private = db_result(db_query('SELECT private FROM {node_access_example} WHERE nid = %d', $node->nid));
      break;
    case 'insert':
      db_query('INSERT INTO {node_access_example} (nid, private) VALUES (%d, %d)', $node->nid, $node->private);
      break;
    case 'update':
      db_query('UPDATE {node_access_example} SET private = %d WHERE nid = %d', $node->private, $node->nid);
      break;
    case 'delete':
      db_query('DELETE FROM {node_access_example} WHERE nid = %d', $node->nid);
      break;
  }
