Modifying a plugin to redirect a user back to their primary blog if they are logged in

Hi all,

I am disgustingly new at WordPress, plugins, and getting my site to do what I want. But this CMS has so many opportunities, I had to stick with it.

So I have a Multisite setup. Users are added by site admins, which in that process are a part of that child site by way of primary_blog. I have one parent page that all users log in through, and once logged in, they are automatically redirected to their primary_blog (primary site).

I am using the following code in my mu folder

<?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) . '';

if ($primary_url) {

wp_redirect($primary_url);

die();

}

}

}

return $redirect_to;

}

add_filter('login_redirect','ds_login_redirect', 100, 3);

?>

So that when a user reaches the main site and clicks on the login button, they are logged in and redirected to their primary_blog.

I have blocked out My Sites and Dashboard to regular users. So my issue is that while a user is logged in, if they leave the site and come back to the primary site, they are not returned to their primary blog.

I am looking to modify the above code in such a way that if the user returns to the main site they are automatically redirected to their primary blog if they are logged in.

I have the following code that was meant to help, but it doesn’t do what I need it to do and I am not sure how to incorporate it.

if(is_user_logged_in()) {

$user_info = get_userdata(get_current_user_id());

if ($user_info->primary_blog) {

$primary_url = get_blogaddress_by_id($user_info->primary_blog) . 'wp-admin/';

if ($primary_url) {

echo '<div class="home-link"><a href="' . $primary_url . '">Blog Home</a></div>';

}

}

}

Any help would be so much appreciated. I would like just something I can drop into the MU folder, other than that I’d need help with instructions. I’m such a newbie, I feel terrible, but after racking my brain for a while, I thought the humble thing to do is ask for help.

Thanks everyone for their time and dedication!
