在主题的 func.php 中引入

//排行榜 function get_post_thumbnail_url($post_id) { $thumbnail_url = get_the_post_thumbnail_url($post_id, 'thumbnail'); if (empty($thumbnail_url)) { $content = get_post_field('post_content', $post_id); if (strpos($content, '<img') !== false) { preg_match('/<img.+src=['"]([^'"]+)['"].*>/i', $content, $matches); if (!empty($matches[1])) { $thumbnail_url = $matches[1]; // 验证缩略图URL是否有效 if (!filter_var($thumbnail_url, FILTER_VALIDATE_URL)) { $thumbnail_url = ''; } } } } return $thumbnail_url; }
