node_access_example_node_grants($account, $op)
contributions/docs/developer/examples/node_access_example.module, line 93

Description

Implementation of hook_node_grants().

Tell the node access system what GIDs the user belongs to for each realm. In this example, we are providing two realms: the example realm, which has just one group id (1) and the user is either a member or not depending upon the operation and the access permission set.

We are also setting up a realm for the node author, though, to give it special privileges. That has 1 GID for every UID, and each user is automatically a member of the group where GID == UID.

Code

function node_access_example_node_grants($account, $op) {
  if ($op == 'view' && user_access('access private content', $account)) {
    $grants['example'] = array(1);
  }

  if (($op == 'update' || $op == 'delete') && user_access('edit private content', $account)) {
    $grants['example'] = array(1);
  }

  $grants['example_author'] = array($account->uid);
  return $grants;
}
