Unexpected getLevel values in autonav

Permalink
Concrete 5.3.1.1

I've created a couple of custom autonav views to provide a common dropdown nav menu at the top of page and a location-specific popout menu at the side of the page. Both use a test on the item level like

$thisLevel = $ni->getLevel();
  if ($thisLevel > $lastLevel) {


to determine closing A LI and UL tags and so forth; basically a minor revision of concrete/blocks/autonav/view.php

However, I seem to be getting odd values for $ni->getLevel in relation to the position of items in the menu; some of the offending items are single pages; others may have been moved in the sitemap hierarchy. Example - the numbers in square brackets are the level and previous level respectively:

# NCETA[1, 0]
  * About Us[2, 1]
      o Strategic Context[3, 2]
        + Strategic Directions[3, 3]
        + Business Plan[3, 3]
        + Annual Reports[2, 3]
      o Partnerships[2, 2]
      o Board of management[2, 2]
      o Contact Us[2, 2]
      o Staff[1, 2] (single page)
  * Publications[1, 1] (single page)
  * Research & Projects[2, 1]
      o Current Projects & Research[2, 2]
      o Past Projects & Research[0, 2]


This results in extra closing tags in some cases which fouls up the page validation and I suspect may also be causing me some major problems in IE6 with popouts and dropdowns. Surprise :-)

Any ideas where I might look to try and resolve this?

It looks like the level is for the next item in the list, not the current item. So your values are [next item, current item].

Does a normal autonav produce valid html?

BTW all the logic for the autonav is in /concrete/blocks/autonav/controller.php

The following code snippet produces the level values in my first post:
$_c = $ni->getCollectionObject();
    /* Exclude any entries marked not for general navigation display, or not for top menu display */
      if (!$_c->getCollectionAttributeValue('exclude_nav') && !$_c->getCollectionAttributeValue('exclude_topNav') ) {
         $thisLevel = $ni->getLevel();
      echo "$thisLevel, $lastLevel";  // Debug echo

Unless I misunderstand what getLevel() returns, that should show the current and previous levels??

Creating a test autonav with no custom template (should then use the default autonav view) returns no HTML errors in the menu block, so I guess I need to revisit my custom view :-(

I'd be interested to know which of the db tables holds the page structure, particularly the item level?

I'm looking into the controller code as well.

Thanks for your response!
