Question

How do I detect if a category has Include in Navigation Menu set to NO?

Answer 1

include_in_menu is an attribute so you can use,

if (!$category->getIncludeInMenu()) ...

Answer 2

This worked for me

 $category->load();
//$category->getIncludeInMenu() returns 1 if set to yes, returns 0 if set to no
if(!$category->getIncludeInMenu())
...
