我正在使用自定义贴子类型，但导航菜单无法获取.current-menu-item 在我的custom post archive page 菜单项。事实上，当我在那一页或任何custom posts, 不是cpt archive菜单项获取当前类，而是指向文章的菜单项获取.current-menu-item （我的博客页面）。

经过几个小时的google测试和黑客攻击，我发现了这个thread on wordpress 下面是经过编辑的解决方案修复版本的副本：

// As of WP 3.1.1 addition of classes for css styling to parents of custom post types doesn\'t exist.
// We want the correct classes added to the correct custom post type parent in the wp-nav-menu for css styling and highlighting, so we\'re modifying each individually...
// The id of each link is required for each one you want to modify
// Place this in your WordPress functions.php file

function remove_parent_classes($class)
{
  // check for current page classes, return false if they exist.
    return ($class == \'current_page_item\' || $class == \'current_page_parent\' || $class == \'current_page_ancestor\'  || $class == \'current-menu-item\') ? FALSE : TRUE;
}

function add_class_to_wp_nav_menu($classes)
{
     switch (get_post_type())
     {
        case \'artist\':
            // we\'re viewing a custom post type, so remove the \'current_page_xxx and current-menu-item\' from all menu items.
            $classes = array_filter($classes, "remove_parent_classes");

            // add the current page class to a specific menu item (replace ###).
            if (in_array(\'menu-item-171\', $classes))
            {
               $classes[] = \'current_page_parent\';
         }
            break;
     }
    return $classes;
}
add_filter(\'nav_menu_css_class\', \'add_class_to_wp_nav_menu\');

当我们在存档页面或以更干净的方式在其中一个自定义帖子上时，有没有其他想法来选择与自定义帖子存档页面相对应的菜单项？

换句话说，归档模板不应该从框中选择自己的菜单项

我从来没有想过在wordpress导航菜单中突出某个元素可能是自定义帖子类型的问题，我对此有点失望。无论如何，下面是我用来管理自定义帖子（艺术家）的代码的n表：

artist.php:

/****************************************************************
* Custom Post Type
****************************************************************/

add_action( \'init\', \'custom_post_artist\' );
function custom_post_artist()
{
  $labels = array(
    [...]
    );

  register_post_type( \'artist\',
    array(
      \'labels\' => $labels,
      \'public\' => true,
      \'menu_position\' => 15,
      \'supports\' => array( \'title\', \'editor\', \'comments\', \'thumbnail\', \'revisions\', \'excerpt\'),
      \'show_in_nav_menus\' => true,
      \'show_in_menu\' => true,
      \'taxonomies\' => array( \'artist_genre\', \'artist_music_type\' ),
      \'has_archive\' => \'artistes\',
      \'rewrite\' => array( \'slug\' => __(\'artistes\', \'ppdev\'), \'with_front\' => False )
      )
    );
}

/****************************************************************
* Templates
****************************************************************/

add_filter( \'template_include\', \'include_tpl_function\', 1 );
function include_tpl_function( $template_path )
{
  if ( get_post_type() == \'artist\' )
  {
    if ( is_single() )
    {
      // checks if the file exists in the theme first,
      // otherwise serve the file from the plugin
      if ( $theme_file = locate_template( array(\'single-artist.php\') ) )
      {
        $template_path = $theme_file;
      }
      else
      {
        $template_path = ARTIST_PATH . \'templates/single-artist.php\';
      }
    } 
    else if( is_archive() )
    {
      if ( $theme_file = locate_template( array(\'archive-artist.php\') ) )
      {
        $template_path = $theme_file;
      }
      else
      {
        $template_path = ARTIST_PATH . \'templates/archive-artist.php\';
      }
    }
  }
  return $template_path;
}

archive-artist.php:

      <!-- Start the Loop -->         
      <?php while ( have_posts() ) : the_post();

      $thumbnail_attr = array(
        \'class\' => "aligncenter",
        \'alt\' => get_the_title()
      );

      <h2>
        <a title="<?php the_title(); ?>" href="<?php the_permalink(); ?>">
          <?php the_title(); ?>

      if ( has_post_thumbnail() ) : ?>
          <a title="<?php the_title(); ?>" href="<?php the_permalink(); ?>">

      <?php endif; ?>
      <?php endwhile; ?>

     <!-- Display page navigation -->
   <?php global $wp_query;
   if ( isset( $wp_query->max_num_pages ) && $wp_query->max_num_pages > 1 ) { ?>
   <nav id="<?php echo $nav_id; ?>">
     <div class="nav-previous"><?php next_posts_link( \'<span class="meta-nav">&larr;</span> Previous artists\' ) ); ?></div>
     <div class="nav-next"><?php previous_posts_link( \'Next artists <span class= "meta-nav">&rarr;</span>\' ); ?></div>
   </nav>
   <?php };
  endif; ?>
 </div>
