WP多站点-从一个子站点创建和更新网络范围内的帖子

Question

我有Wordpress Multisite安装。有5个子站点。我想发布和编辑子站点No中的所有帖子。 1.即我想在子网站no上发布帖子。 1，然后单击“发布”按钮，我希望将此帖子发布到我的网络的每个子站点上。我还想编辑子站点编号上的帖子。 1，并在点击按钮更新后，希望在整个子网站网络上更新此帖子。

我能够编写脚本，使我能够在每个子站点上创建新帖子，但是当我更新帖子时，脚本会创建新帖子而不是编辑帖子，这是主要问题。我已经尝试过另一个钩子，例如“ edit_post”或“ post_updated”，但是它没有用。我也无法使用WP REST API来达到目的。

有人有创意吗？

在此先感谢您的帮助。
