Adds a new role to WordPress.

NB: This setting is saved to the database (in table wp_options, field wp_user_roles), so it might be better to run this on theme/plugin activation

add_role() 参数


When to call

Make sure that the global $wp_roles is available before attempting to add or modify a role. The best practice of course is to use your plugin- or theme-activation hook to make changes to roles (since you only want to do it once!).

mu-plugins will load too early, so use an 动作 hook (like 'init') to wrap your add_role() call if you're doing this in the context of an mu-plugin.

Delete existing role

If you are defining a custom role, and adding capabilities to the role using add_role(), be aware that modifying the capabilities array and re-executing add_role() will not necessarily update the role with the new capabilities list. The add_role() function short-circuits if the role already exists in the database.

The workaround in this case is to precede your add_role() call with a remove_role() call that targets the role you are adding.

This is for development only. Once you have nailed down your list of capabilities, there's no need to keep the remove_role() code, though there is, in fact, no harm in doing so.
