我正在使用以下作者存档代码：

                 * what author we\'re dealing with (if that is the case).

我需要从作者页面中排除一个类别。然而，我不能让它工作。

如果添加

query_posts (query_posts( \'cat=-x\' ); where x is category to skip), 

我总是看到一篇/同一篇不属于所选类别的帖子，而不是循环浏览帖子。

有什么建议，为什么这可能不起作用？

function wpd_exclude_author_category( $query ) {
    if ( $query->is_author() && $query->is_main_query() ) {
        $query->set( \'category__not_in\', array( 42 ) );
    }
}
add_action( \'pre_get_posts\', \'wpd_exclude_author_category\' );
