Question

我正在使用代码段来包含来自自定义帖子类型的帖子＆＃34;视频＆＃34;在类别中导致WordPress。

代码是：

add_filter('pre_get_posts', 'query_post_type');
function query_post_type($query) {
    if(is_category() || is_tag()) {
        $post_type = get_query_var('post_type');
        if($post_type)
            $post_type = $post_type;
        else
            $post_type = array('post','videos');
        $query->set('post_type',$post_type);
    return $query;
    }
}

在返回正确结果方面，此代码确实有效。然而，它奇怪地使网站菜单不起作用。在调查中，我收到以下错误：

Notice: Undefined property: stdClass::$db_id in /homepages/16/d673645047/htdocs/SiteName/wp-includes/class-wp-walker.php on line 136

Notice: Undefined property: stdClass::$ID in /homepages/16/d673645047/htdocs/SiteName/wp-includes/class-walker-nav-menu.php on line 204

有谁知道如何解决此问题？我已经测试过，上面的代码片段就是问题所在。我在网上看到这是一个已知问题，但一直无法找到解决方案。

我不确定您的问题具体是什么，但我查询自定义帖子类型的方法略有不同。

<?php
$args = array( 'post_type' =>  'testimonials_list', 'order'   => 'ASC'  ); 
$postslist = get_posts( $args );    
foreach ($postslist as $post) :  setup_postdata($post); ?> //Do Something <?php endforeach;?>

在类别循环中包括自定义帖子类型 - Walker Nav错误
