我正在使用Yoast SEO插件，我试图使用'wpseo_sitemap_entry'过滤器从帖子XML站点地图手动排除帖子，但到目前为止没有运气。
这是我目前的代码：
function sitemap_exclude_post( $url, $type, $post) {
if($post->ID == 6298 ) {
return false;
}
return $url;
}
add_filter( 'wpseo_sitemap_entry', 'sitemap_exclude_post', 1, 3 );
任何建议将不胜感激？
注意：我知道可以通过手动输入帖子ID通过Yoast插件的后端来完成，但我需要通过过滤器来完成。上面的代码将在以后进一步更改，以自动从wordpress中的类别获取帖子的帖子ID（single.php）。
我知道这个问题已经得到了解答但是我需要一个更加动态的方法来解释@ clodclod91所解释的问题，因为我不止一次收到这个问题，我写了一些关于如何以“更流畅的方式”做到最好的代码而不是硬编码值。
我希望它可以帮助一些人。
我还写了一篇文章，附有更多解释。读它here。
/**

function beee_get_sitemap_excludes_transient() {
// get transient
$output = get_transient( 'beee_exclude_sitemap' );
// if transient returns false, create it

我在我的问题中发布的上述代码工作正常。
我刚按下Yoast的仪表板“排除帖子”部分中的“保存更改”按钮，它就可以了。不确定如何，但它的工作原理。
可以使用update_option函数。
$array = array(
"excluded-posts" => 6298
);
update_option('wpseo_xml', $array);
也应该在add_filter钩子里面工作。 update_option是一个在表选项中插入或更新的wp函数。关于XML Sitemap的Yoast SEO的wp_options表内的关键是wpseo_xml。在值中有一个包含其他信息的数组：

s: 22: "disable_author_sitemap";
b: 1;
s: 22: "disable_author_noposts";
b: 1;
