من با این روش به خواستم رسیدم 
اگه راه بهتری پیشنهاد دارید ممنون میشم بفرمایید

داخل helper view

function view($path, $data = [], $layout = null)
{
    $path = str_replace('.', DIRECTORY_SEPARATOR, $path);
    $path_explode = explode('/', $path);
    $full_path = BASEPATH . "views/$path.php";
    $is_file = is_readable($full_path) && file_exists($full_path);
    if ($path_explode[0] == 'frontend') {
        $data = inject_menu($path_explode[0]);
    }
    if (is_null($layout)) {
        $is_file ? buffering($full_path, $data, $path_explode[0]) : include_once BASEPATH . "views/error/404.php";
    }
    $is_file ? buffering($full_path, $data) : include_once BASEPATH . "views/error/404.php";
}
function inject_menu($path)
{
    $categoryModel = new Category;
    $categoryLevelOne = $categoryModel->get('*', ['parent_id' => 0]);
    foreach ($categoryLevelOne as $LevelOne) {
        $categoryLevelTwo[$LevelOne['id']] = $categoryModel->inner_join('photos', 'id', 'entity_id', 'categories.parent_id' . '=' . $LevelOne['id']);
    }
    return  [
        'categoryLevelOne' => $categoryLevelOne,
        'categoryLevelTwo' => $categoryLevelTwo
    ];
}
function buffering($full_path_view, $data, $dir = null)
{
    if (!is_null($dir)) {
        ob_start();
        extract($data);
        include_once $full_path_view;
        $view = ob_get_clean();
        include_once BASEPATH . "views/$dir/layouts/master.php";
    }
    include_once $full_path_view;
}
