Wordpress Yoast 从 XML 站点地图中排除帖子

Question

我正在使用 Yoast SEO 插件，我正在尝试使用 'wpseo_sitemap_entry' 过滤器从 posts XML 站点地图中手动排除 posts 但到目前为止运气不好。

这是我当前的代码：

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 Yoast 插件的后端手动输入 post ID 来完成，但我需要通过过滤器来完成。上面的代码后面会进一步修改，自动从wordpress的某个分类中获取posts(single.php)的Post个ID。

Answer 1

您可以从 Yoast 管理界面轻松完成：

Answer 2

我在问题中发布的上述代码运行良好。

我只是按下了 Yoast 仪表板 "Exclude Posts" 部分中的 "save changes" 按钮，它起作用了。不知道如何，但它的工作。

Answer 3

可以使用update_option功能。

$array = array(
  "excluded-posts" => 6298
);

update_option('wpseo_xml', $array);

也应该在 add_filter 钩子中工作。 update_option 是一个 wp 函数，可以在 table 选项中插入或更新。 XML 站点地图的 Yoast SEO wp_options table 中的键是 wpseo_xml。在值中有一个包含其他信息的数组：

a:18: {
s: 22: "disable_author_sitemap";
b: 1;
s: 22: "disable_author_noposts";
b: 1;
s: 16: "enablexmlsitemap";
b: 1;
s: 16: "entries-per-page";
i: 1000;
s: 14: "excluded-posts";
s: 7: "1,2,3,4";
s: 38: "user_role-administrator-not_in_sitemap";
b: 0;
s: 31: "user_role-editor-not_in_sitemap";
b: 0;
s: 31: "user_role-author-not_in_sitemap";
b: 0;
s: 36: "user_role-contributor-not_in_sitemap";
b: 0;
s: 35: "user_role-subscriber-not_in_sitemap";
b: 0;
s: 36: "user_role-authors_tes-not_in_sitemap";
b: 0;
s: 40: "user_role-authors_academy-not_in_sitemap";
b: 0;
s: 30: "post_types-post-not_in_sitemap";
b: 0;
s: 30: "post_types-page-not_in_sitemap";
b: 0;
s: 36: "post_types-attachment-not_in_sitemap";
b: 1;
s: 34: "taxonomies-category-not_in_sitemap";
b: 0;
s: 34: "taxonomies-post_tag-not_in_sitemap";
b: 0;
s: 37: "taxonomies-post_format-not_in_sitemap";
b: 0;

}

我知道这个问题已经得到了回答，但我需要一种更动态的方法来解释@clodclod91 的解释，因为我不止一次收到这个问题，所以我写了一些关于如何在 [=18] 中做到最好的代码=] 而不是对任何值进行硬编码。

希望对一些人有所帮助。

我还写了一篇 post，其中有更多的解释。阅读 here.
