Allows access control for Drupal book nodes.

Code

function book_access_form_alter($form_id, &$form) {
  if ($form_id == 'book_node_form' && isset($form['parent'])) {
    _book_access_restrict_options($form['parent']['#options']);
  }

  // When an outline is modified, taxonomy is changed, but the node is not
  // saved, so node grants can become broken if a book page is moved into
  // another book. so we fix that by adding an additional #submit callback
  // that rebuilds the grants when the book outline is modified.
  if ($form_id == 'book_outline_form') {
    $form['#submit'][] = '_book_access_build_node_grants';
  }
