   I'm trying to add a custom class to the menus that are generated. I am adding a custom field to each page/post and I need the value to be in the class. Here is my code.
   

   add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);
   	function special_nav_class($classes, $item){
   		$color = get_post_custom($item->object_id, 'color', TRUE);
   		echo "[".$item->object_id."][".$color."]";
   		if($color == "green"){
   			$classes[] = 'green';
   		}else if($color == "yellow"){
   			$classes[] = 'yellow';
   		}else{
   			$classes[] = 'pink';
   		}
   		return $classes;
   	}

   The part the does the echo is spitting out the correct ID but the $color is always an array. I can't figure out what is going wrong.

   get_post_custom only takes one argument and always returns an array.

   Function Reference/get post custom

   I think you're looking for get_post_meta:

   $color = get_post_meta( $item->object_id, 'color', true );

   Function Reference/get post meta
