我正在尝试按作者筛选wp\\u dropdown\\u pages函数的结果，以下是我到目前为止得到的结果。

$dropdown_args = array(
            \'post_type\'        => $post->post_type,
            \'exclude_tree\'     => $post->ID,
            \'selected\'         => $post->post_parent,
            \'name\'             => \'parent_id\',
            \'show_option_none\' => __(\'(no parent)\'),
            \'sort_column\'      => \'menu_order, post_title\',
            \'echo\'             => 0,
            \'authors\'          => \'-11\',
        );
wp_dropdown_pages( $dropdown_args );
