在 wordpress 中为多个站点创建编辑器

Question

在 Wordpress 多站点平台上，通常如果我创建“编辑”用户帐户，该用户只能对正在创建的站点执行职责。

但是我想创建一个特殊的编辑帐户，可以在所有站点（多个站点）上执行编辑职责

谁能指导我如何创建这样的用户？

Answer 1

我认为您可以使用插件Multisite user management 做您需要的事情。这应该允许您将用户和角色复制到所需的站点...或者您可以创建一个新的管理员帐户。

Answer 2

我正在检查来自Felipe's answer 的多站点用户管理插件的代码，并决定进行概念验证。

以下仅限网络的插件添加了以下选项：

当我们在下拉列表中选择一个用户并更新设置时，该用户被添加为网络的所有站点中的编辑器。
创建新网站时，也会添加此用户。

重要提示：

• 有noundo功能，更新设置后，您只能逐个站点删除/更改用户。李>
