husobj快速修复：

function my_page_css_class( $css_class, $page ) {
    global $post;
    if ( $post->ID == $page->ID ) {
        $css_class[] = \'current_page_item\';
    }
    return $css_class;
}
add_filter( \'page_css_class\', \'my_page_css_class\', 10, 2 );

您可以使用此代码在菜单中激活父帖子类型：

<?php

add_action(\'nav_menu_css_class\', \'add_current_nav_class\', 10, 2 );

function add_current_nav_class($classes, $item) {

    // Getting the current post details
    global $post;

    // Getting the post type of the current post
    $current_post_type = get_post_type_object(get_post_type($post->ID));
    $current_post_type_slug = $current_post_type->rewrite[slug];

    // Getting the URL of the menu item
    $menu_slug = strtolower(trim($item->url));

    // If the menu item URL contains the current post types slug add the current-menu-item class
    if (strpos($menu_slug,$current_post_type_slug) !== false) {

       $classes[] = \'current-menu-item\';

    }

    // Return the corrected set of classes to be added to the menu item
    return $classes;

}

?>

我想添加一个适合我的解决方案。

我有自定义分类法的自定义帖子类型，并希望列出这些帖子，只要它们位于特定的自定义类别中—当前页面类位于li.

上述代码^*生成了所有帖子的列表，但没有过滤类别
^{* [编者注]答案可能会改变其顺序，但不确定引用的代码是什么}

我的解决方案来自该代码，不确定它是否是最佳实践，但它是有效的。。

<?php
// get current page/post ID
$pageID = get_the_ID();
query_posts( array( \'post_type\' => \'developments\', \'custom_cat\' => \'current\' ) );
if ( have_posts() ) : 
    while ( have_posts() ) : 
        the_post();
        // test if current page/post ID matches
        if ( $post->ID == $pageID ) {
            $class = \'current_page_item\';
        } else {
            $class = \'\';
        }
?>
        <li <?php if ($class != \'\') echo \'class="\'.$class.\'"\'; ?>>
            <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
        </li>
<?php 
    endwhile; 
endif; 
wp_reset_query(); 
?>

您需要将其添加到函数中。php：

function kct_page_css_class( $css_class, $page, $depth, $args, $current_page ) {
  if ( !isset($args[\'post_type\']) || !is_singular($args[\'post_type\']) )
    return $css_class;

  global $post;
  $current_page  = $post->ID;
  $_current_page = $post;
  _get_post_ancestors($_current_page);

  if ( isset($_current_page->ancestors) && in_array($page->ID, (array) $_current_page->ancestors) )
    $css_class[] = \'current_page_ancestor\';
  if ( $page->ID == $current_page )
    $css_class[] = \'current_page_item\';
  elseif ( $_current_page && $page->ID == $_current_page->post_parent )
    $css_class[] = \'current_page_parent\';

  return $css_class;
}
add_filter( \'page_css_class\', \'kct_page_css_class\', 10, 5 );

if(site_url()."/".get_post_type() == $menu_item->url || site_url()."/".$post->post_name == $menu_item->url){#STUFF TO IDENTIFY ON FRONT}
