Update User Role Across Network when Main Site User is Updated

Question

I'm using a slightly modified copy of the Multi Site User Management plugin to keeps users synced across a multisite network, but have one problem with it. When a user's role is updated on the main site, the role is NOT updated on the sub site. In order for everything to work correctly, user roles must stay in sync.

I've been looking without success, so is there an action that runs when a user is updated? I know about the profile_update and wp_update_user functions / hooks, but neither of these work because the user role is updated via an external function. So I need a new way of always syncing user roles.

Any ideas?

Answer 1

I've found a way around the problem. It's not a "fix", but rather a way to get around the problem of needing synchronized user roles. Instead of trying to make all user roles match up, I decided to only check the user roles for the main site. see my function below for how I did it:

/*
* Function to check a specified user from a subsite against
* the role of that same user on the main site
*
* @param int $site_to_check the id of the site to check the user's role from
* @param int $user_id the user's id to check
*/
function cgc_check_for_citizen($site_to_check = 1, $user_id = null) {
    if(!isset($user_id)) {
        return false;
    }
    $citizen = false;

    global $blog_id;

    if($blog_id == 1) { // we're on the main site
        if(user_can($user_id, 'read_citizen')) {
            $citizen = true;
        }
    } else {
        switch_to_blog($site_to_check);
            if(user_can($user_id, 'read_citizen')) {
                $citizen = true;
            }
        restore_current_blog();
    }
    return $citizen;
}

I'm thinking if you can't figure it out, no one can. ;(

Anyway, this plugin automatically updates user roles for sub-sites based on the main site. So maybe you can extract the code:

Hi i'm not sure whether this plugin will help you or not. But give it a try. Try scribu's proper-network-activation plugin
