Gets a book menu link by its menu link ID.

Like menu_link_load(), but adds additional data from the {book} table.

Do not call when loading a node, since this function may call node_load().

Parameters

$mlid: The menu link ID of the menu item.

Return value

A menu link, with the link translated for rendering and data added from the {book} table. FALSE if there is an error.

File

drupal-7.x/modules/book/book.module, line 1356

Allows users to create and organize related content in an outline.

Code

function book_link_load($mlid) {
  if ($item = db_query("SELECT * FROM {menu_links} ml INNER JOIN {book} b ON b.mlid = ml.mlid LEFT JOIN {menu_router} m ON m.path = ml.router_path WHERE ml.mlid = :mlid", array(
    ':mlid' => $mlid,
  ))->fetchAssoc()) {
    _menu_link_translate($item);
    return $item;
  }

  return FALSE;
}
