Nav / menu current-item-parent not avaliable

Try removing the , after 'main-menu'

Oh gosh, how lame of me to not catch that ",". Thank you, Zac! I promptly removed it, however my result is still the same. Dang.

Perhaps I'm missing something when setting up pages? The wp-portfolio project did not require saving a separate single-work page in the admin, so I followed suit. I had also toyed around with making a single-work.php template page and setting the Work page as its parent via the WP Admin. I didn't get the desired result with this either. Hmmm.

Okay, one problem down, one more to go ;p

There are a number of different approaches to this now that I fully get what you're trying to do. Try a few of these top results here. It's definitely something that others have created work arounds for: https://www.google.com/search?q=active+class+for+custom+post+pages

I'm pretty sure the parent pages association won't work, although I like the clever thinking!

Thank you for the help with a better search. Often times it is most important to know what questions to ask!

After wrestling with this for 5-6 hours I'm feeling like a dullard, and still not solving the problem.

In this thread -> http://wordpress.stackexchange.com/questions/3014/highlighting-wp-nav-menu-ancestor-class-w-o-children-in-nav-structure The author seems to have the same problem. However, what seems to be a popular answer, I cannot quite work out. It involves adding another menu item which I, and I assumed the author doesn't need?

I tried other suggestions without progress.

The one seemingly simple snippet I found was on the Codex http://codex.wordpress.org/Function_Reference/wp_nav_menu

Adding Conditional Classes to Menu Items

<?php
add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);
function special_nav_class($classes, $item){
     if(is_single() && $item->title == "Blog"){ //you can change the conditional from is_single() and $item->title
         $classes[] = "special-class";
     }
     return $classes;
}
?>

I changed '$item->title' to get_post_type() == 'portfolio'.

One problem is that this adds the class 'special-class' to every nav item. I don't know how to apply it to only a specific nav item.

Another thing that I don't understand is that making this an anonymous function does not work.

At any rate, I can use this 'special-class' combined with the specific 'menu-item-#' to style with. However, I'm not very pleased with the solution as it's a bit of a hack job.

Okay, let's take a slightly different approach. There are some plugins that address this. Try testing one or two of theme out and see if that can help?

Did anyone find a solution to this problem? I went to the links suggested by Zac and found this recommendation for the problem. He suggests adding this to the functions.php file but it gives me an error. Any thoughts?

// Add class of current-page-ancestor to Custom Post Types function remove_parent($var) { if ($var == ‘current_page_parent’ || $var == ‘current-menu-item’ || $var == ‘current-page-ancestor’) { return false; } return true; }

function tg_add_class_to_menu($classes) { // Add custom post type name if (is_singular(‘cakes’)) { $classes = array_filter($classes, “remove_parent”);

// Need to add menu item number if (in_array(‘menu-item-56?, $classes)) $classes[] = ‘current-page-ancestor’; }

return $classes; }

if (!is_admin()) { add_filter(‘nav_menu_css_class’, ‘tg_add_class_to_menu’); }
