This module allows administrators to make nodes viewable by specific 'access groups'. Each access group can contain any number of roles. If a node is not assigned to any access groups, it will remain viewable by all users.

Code

function simple_access_nodeapi(&$node, $op) {
  switch ($op) {
    case 'prepare':
      if (!isset($node->simple_access)) {
        $node->simple_access = array();
      }
      break;
    case 'load':
      $extra = array();
      $result = db_query('SELECT na.gid, na.view, na.update, na.delete FROM {simple_access_node} na WHERE na.nid = %d', $node->nid);
      while ($grant = db_fetch_array($result)) {
        $gid = $grant['gid'];
        unset($grant['gid']);
        $extra[$gid] = $grant;
      }
      $node->simple_access = $extra;
      break;
    case 'update':
    case 'insert':
      db_query('DELETE FROM {simple_access_node} WHERE nid = %d', $node->nid);
      if (isset($node->simple_access)) {
        foreach ($node->simple_access as $gid => $access) {
          if ($access['view'] || $access['update'] || $access['delete']) {
            db_query("INSERT INTO {simple_access_node} (`nid`, `gid`, `view`, `update`, `delete`) VALUES (%d, %d, %d, %d, %d)", $node->nid, $gid, $access['view'], $access['update'], $access['delete']);
          }
        }
      }
      break;
    case 'delete':
