Auto Nav Display Second Level plus current parent.

Permalink
I currently have an auto nav in a sidebar. My code below shows all pages from the second level and below. If I wanted to display the top most parent of the current page, how would I go about that?

For example, my tree:

Resources
--Downloads
--FAQs
----General
----Selling
--Videos

I want to display Resources at the very top of the auto nav. Right now it's just:

Downloads
FAQs
--General
--Selling
Videos

<?php 
   $nh = Loader::helper('navigation');
   $path = $nh->getTrailToCollection($c);
   $c = Page::getCurrentPage();
   if ( count($path) > 1) {
      $revPath = array_reverse($path);
      $sectionPage = $revPath[1];
   } elseif ( count($path) == 1) {
      $sectionPage = $c;
   } else {
      $sectionPage = Page::getByID(HOME_CID);
   }
   $cID = $sectionPage->getCollectionID();
   $subNavBlock = BlockType::getByHandle('autonav');
   $subNavBlock->controller->displayPages = 'second_level'; /* top, second_level, third_level, above, current, below, custom */

Any help would be great. Thanks!

This site:http://www.webli.us/cheatsheet/doku.php#display_a_page_s_parent_pag...
has a lot of useful snippets of code you can use.

Looks like this will work.

<?php
  $page=Page::getByID($c->getCollectionParentID());
  echo $page->getCollectionName();
?>

This works if I want to display the parent of the current page, but let's say I always want to show the Top Level parent regardless of what child page you're on. How would I do that?

I found one solution, although it may not be the most efficient.

<?php 
   $nh = Loader::helper('navigation');
   $path = $nh->getTrailToCollection($c);
   $c = Page::getCurrentPage();
   if ($c->cID > 1) {
     $arrTrail = array_reverse($nh->getTrailToCollection($c));
     $objHomePage = $arrTrail[0]; // Home page object;
     // If we're on a top-level page then our $arrTrail array will only have the home page object
     // so we test to see if its Page object exists
     $objTopPage = is_object($arrTrail[1]) && $arrTrail[1] instanceof Page && !$arrTrail[1]->error ? $arrTrail[1] : $c;
     // If we have a valid top page Page object we retrieve 
     $title = $objTopPage->getCollectionName();
     $url = $nh->getLinkToCollection($objTopPage);
     // print parent
     echo '<h5><a class="current" href="' . $url . '"' . '>' . $title . '</a>' . '</h5>';

Probably too late but someone might find this useful...

Add this to the top of the autonav:
foreach ($navItems as $ni) {
   if ($ni->level = 1) {
     $parent = Page::getByID($ni->cObj->getCollectionParentID());
     break;
   }
}

then you can add this just before the output foreach ni:
echo '<li class="parent"><a href="' . $parent->getCollectionPath() . '" target="_self" class="parent">' . $parent->getCollectionName() . '</a></li>';

A little dirty but works well and efficiently.
