Phperrorcode：

WordPress数据库错误您的SQL语法有错误；检查与您的MySQL服务器版本对应的手册以获取正确的语法，以在第1行的''附近使用SELECT SELECT term_taxonomy_id FROM wp_term_taxonomy WHERE term_taxonomy_id！= 0 AND parent =由require（'wp-blog-header.php'）制成，wp，WP-> main，WP-> query_posts，WP_Query-> query，WP_Query-> get_posts

是否提到我在运行此代码或其他内容之前必须先包含wp-blog-header.php文件。
