 На одном из проектов возникла необходимость вывести меню в шапке сайта со всеми вложенными пунктами. Изначально меню было выведено с помощью кода в page.tpl: <pre> <code class="language-php"><?php print theme( 'links__system_main_menu', array( 'links' => $main_menu, 'attributes' => array( 'id' => 'main-menu-links', 'class' => array('links', 'clearfix'), ), ) ); ?></code></pre> Но с этим кодом одна проблема - меню выводится только первого уровня. В целом такую задачу можно было бы решить просто выводом меню блоком в новый регион. Но не хотелось менять классы, поэтому нашёл другое решение. Оно выводит меню сайта со всеми уровнями вложенности, классами(active-trail, active), в заданное место сайта. <pre> <code class="language-php"><?php function _menu_tree_full_data($menu_name) { $tree = &drupal_static(__FUNCTION__, array()); // Check if the active trail has been overridden for this menu tree. $active_path = menu_tree_get_path($menu_name); // Generate a cache ID(cid) specific for this page $item = menu_get_item($active_path); $cid = "links:$menu_name:full:{$item['href']}:{$GLOBALS['language']->language}"; // Did we already build this menu during this request? if(isset($tree[$cid])) return $tree[$cid]; // If the static variable doesn't have the data, check {cache_menu}. $cache = cache_get($cid, 'cache_menu'); if($cache && isset($cache->data)) { $tree_params = $cache->data; if(isset($tree_params)) return $tree[$cid] = menu_build_tree($menu_name, $tree_params); } $tree_params = array( 'min_depth' => 1, 'max_depth' => null, ); // Parent mlids; used both as key and value to ensure uniqueness. // We always want all the top-level links with plid == 0. $active_trail = array(0 => 0); // Find a menu link corresponding to the current path. If $active_path // is NULL, let menu_link_get_preferred() determine the path. $active_link = menu_link_get_preferred($active_path, $menu_name); // The active link may only be taken into account to build the // active trail, if it resides in the requested menu. Otherwise, // we'd needlessly re-run _menu_build_tree() queries for every menu // on every page. if(@$active_link['menu_name'] == $menu_name) { // Use all the coordinates, except the last one because there // can be no child beyond the last column. for($i = 1; $i < MENU_MAX_DEPTH; $i++) { if($active_link['p' . $i]) $active_trail[$active_link['p' . $i]] = $active_link['p' . $i]; } } $parents = $active_trail; do { $result = db_select('menu_links', NULL, array('fetch' => PDO::FETCH_ASSOC)) ->fields('menu_links', array('mlid')) ->condition('menu_name', $menu_name) //->condition('expanded', 1) ->condition('has_children', 1) ->condition('plid', $parents, 'IN') ->condition('mlid', $parents, 'NOT IN') ->execute(); $num_rows = FALSE; foreach($result as $item) { $parents[$item['mlid']] = $item['mlid']; $num_rows = TRUE; } } while($num_rows); $tree_params['expanded'] = $parents; $tree_params['active_trail'] = $active_trail; // Cache the tree building parameters using the page-specific cid. cache_set($cid, $tree_params, 'cache_menu'); // Build the tree using the parameters; the resulting tree will be cached by _menu_build_tree(). return $tree[$cid] = menu_build_tree($menu_name, $tree_params); } ?></code></pre>
