Redirect back to blog instead of dashboard in multisite

Update: The bahaviour occurs when the plugin Better WP Security is active with the Option Hide > Hide Backend is enabled.

“I need to prevent subscribers from entering the dashboard after login”

In a network a user may in fact not belong to any blog at all. SO by default they will(should) always be able to see the “Global Dashboard” @ “/wp-admin/user/”. I won’t add code to my plugin to deny user’s ability to edit their profile.

If a user only belongs to a sub site, they should get a WordPress error page that lists the sites they do have permission to login to.

The default behaviour of WordPress is to redirect a login to the page the user requested to initiate the login. My plugin alone doesn’t change this behaviour.

You can write and add your own plugin to /mu-plugins/ to redirect logins to wherever you like. Here’s an example of a snippet that works for me:

<?php
function ds_login_redirect( $redirect_to, $request_redirect_to, $user )
{
    if ($user->ID != 0) {
        $user_info = get_userdata($user->ID);
        if ($user_info->primary_blog) {
//        $primary_url = get_blogaddress_by_id($user_info->primary_blog) . 'wp-admin/';
           $primary_url = get_blogaddress_by_id($user_info->primary_blog);
           if ($primary_url) {
                wp_redirect($primary_url);
                die();
            }
        }
    }
    return $redirect_to;
}
add_filter('login_redirect','ds_login_redirect', 100, 3);
?>
