Here is how I exclude specific page types from an autonav menu in Concrete5.
Navigate to concrete/blocks/autonav and open the view.php file.
Scroll down to this line:
foreach($aBlocks as $ni) {
$_c = $ni->getCollectionObject();
if (!$_c->getCollectionAttributeValue('exclude_nav')) {
Add this block of code:
$typeHandle = $_c->getCollectionTypeHandle();
if($typeHandle!="page_type"){
Change “page_type” to the handle of page type that you want to exclude from your autonav menu (for example: blog_post).
Now scroll down and add “}” after this line:
$lastLevel = $thisLevel; $i++;
You can also see or download the edited view.php here (this is a text file, so if you want to use it, make sure you save it as a php file!!).
