domain_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL)
domain.module, line 615

Description

Implements hook_nodeapi().

This function is used to provide debugging information and to prep values from the {domain_access} table when editing nodes. Since not all users can see the domain access editing checkboxes, we pass some node_access values as hidden elements.

Code

function domain_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
  switch ($op) {
    case 'prepare':
    case 'load':
      // Append the domain grants to the node for editing.

      $node->editors = array();
      $node->domain_site = FALSE;
      $result = db_query("SELECT gid, realm FROM {domain_access} WHERE nid = %d AND (realm = '%s' OR realm = '%s' OR realm = '%s')", $node->nid, 'domain_id', 'domain_site', 'domain_editor');
      while ($data = db_fetch_object($result)) {
        // Transform the 0 to -1, since {domain_access} is unsigned.
        ($data->gid == 0) ? $gid = -1 : $gid = $data->gid;
        if ($data->realm == 'domain_id') {
          $node->domains[$gid] = $gid;
          if ($gid > 0) {
            $domain = domain_lookup($gid);
            $node->subdomains[] = $domain['sitename'];
          }
          else {
            $node->subdomains[] = variable_get('domain_sitename', variable_get('sitename', 'Drupal'));
