我一直试图验证我的WordPress杂志RSS提要，但仍然有一些我无法删除的错误 .

目前有5个错误：

此Feed无效 . 第54行，第2栏：未定义的项目元素：特色：帖子（6次出现）<featured_post> 1 </ featured_post> <cover_post>常规</ cover_post> <single_fe
... ^第54行，第34列：未定义的项目元素：封面：发布（10次出现）<featured_post> 1 </ featured_post> <cover_post>常规</ cover_post> <single_fe
... ^第54行，第66列：未定义的项目元素：单个：featured_image（5次出现）<featured_post> 1 </ featured_post> <cover_post>常规</ cover_post> <single_fe
... ^第54行，第114列：未定义的项目元素：单个：sidebar_source（10个出现次数）... featured_image> 1blog-side ... ^第54行，第173列：未定义的项目元素：post：views_count（10次出现） ... rce> blog-sidebar8

我进入了 function.php 文件并看到了这个 . 这有点关联，你知道该怎么做吗？谢谢

//Function to add featured image in RSS feeds
function featured_image_in_rss($content)
{
    // Global $post variable
    global $post;
    // Check if the post has a featured image
    if (has_post_thumbnail($post->ID))
    {
        $content = get_the_post_thumbnail($post->ID, 'full', array('style' => 'margin-bottom:10px;')) . $content;
    }
    return $content;
}
//Add the filter for RSS feeds Excerpt
add_filter('the_excerpt_rss', 'featured_image_in_rss');
//Add the filter for RSS feed content
add_filter('the_content_feed', 'featured_image_in_rss');

/*

function featured_image_in_feed( $content ) {
    global $post;
    if( is_feed() ) {
        if ( has_post_thumbnail( $post->ID ) ){
            $output = get_the_post_thumbnail( $post->ID, 'medium', array( 'style' => 'float:right; margin:0 0 10px 10px;' ) );
            $content = $output . $content;
        }
    }
    return $content;
}
add_filter( 'the_content_feed', 'featured_image_in_feed' );
*/

非常感谢你的帮助
