How to add post count to wp_nav_menu?

2 comments

1. Basically the easiest thing should be a callback to the start_el() method of the Walker class.

   // From core:
   apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
   

   Just grab the data (whatever the actual data is and from wherever it comes) and append it.

   add_action( 'walker_nav_menu_start_el', 'wpse_10042_nav_menu_post_count', 10, 4 );
   function wpse_10042_nav_menu_post_count( $output, $item, $depth, $args )
   {
       // Check $item and get the data you need
       printf( '<pre>%s</pre>', var_export( $item, true ) );
       // Then append whatever you need to the $output
       $output .= '';
   
       return $output;
   }
   

2. Have you seen this thread?

   $menu_to_count = wp_nav_menu(array(
       'echo' => false,
       'theme_location' => 'menu'
       ));
   $menu_items = substr_count($menu_to_count,'class="menu-item ');
   echo $menu_items;
