Same name and namespace in other branches

1. 5 private.module \private_nodeapi()

Implementation of hook_nodeapi().

• "delete", "insert", and "update":

The module must track the access status of the node.

File

./private.module, line 185

A tremendously simple access control module -- it allows users to mark individual nodes as private; users with 'access private content' perms can read these nodes, while others cannot.

Code

function private_nodeapi(&$node, $op, $arg = 0) {
  switch ($op) {
    case 'load':
      $result = db_fetch_object(db_query('SELECT * FROM {private} WHERE nid = %d', $node->nid));
      $node->private = $result->private;
      break;
    case 'delete':
      db_query('DELETE FROM {private} WHERE nid = %d', $node->nid);
      break;
    case 'insert':
    case 'update':
      db_query('UPDATE {private} SET private = %d WHERE nid = %d', $node->private, $node->nid);
      if (!db_affected_rows()) {
        db_query('INSERT INTO {private} (nid, private) VALUES (%d, %d)', $node->nid, $node->private);
      }
      break;
  }
}
