如何从WordPress的wp-sitemap.xml中排除特定的帖子?

在 WordPress 5.5 中,引入了一项新功能,它将基本的、可扩展的XML 站点地图功能添加到 WordPress核心。

在 5.5 版中,WordPress 将在/wp-sitemap.xml 使用站点地图索引. 这是包含 WordPress 站点公开的所有站点地图页面列表的主要 XML 文件。默认此功能是开启状态,如果你的站点打开是404,那么可能是主题或插件禁止了它,可以使用wp_sitemaps_enabled来开启:

add_filter( 'wp_sitemaps_enabled', '__return_true' );

站点地图索引最多可包含 50000 个站点地图,单个站点地图最多可包含 2000 个(可过滤的)条目。

默认情况下,站点地图包括主页,所有公共和可公开查询的帖子类型和分类法,以及作者档案。

从站点地图中排除某个特定的帖子

我们常常会有一些特定的帖子,不希望被搜索引擎收录的,那么最好也将它们从站点地图中排除。

过滤器wp_sitemaps_posts_query_args可用于从站点地图中排除特定帖子。下面是我的一个商城,排除购物车和结账页面的例子,将下面的代码加到子主题的functions.php,亲测有效:

// disable cart and check out page
function disable_sitemap_specific_page($args, $post_type) {
if ('page' !== $post_type) return $args;
$args['post__not_in'] = isset($args['post__not_in']) ? $args['post__not_in'] : array();
$args['post__not_in'][] = 23;
$args['post__not_in'][] = 24; 
return $args;
}
add_filter('wp_sitemaps_posts_query_args', 'disable_sitemap_specific_page', 10, 2);

下面是自定义站点地图排除帖子,页面,产品等PHP示例
