How to redirect new WordPress multisite user inside their admin panel after they log in?

Question

Here is the code in my functions.php that redirects users (to their new "Sample Page") when they log in:

function admin_default_page() {  
  return '/wp-admin/post.php?post=2&action=edit';
}

add_filter('login_redirect', 'admin_default_page');

The problem is that the url to which we redirect is missing the users site url. For example, if a user creates a site "Bobs Trucks", it redirects them to

example.com/wp-admin/post.php?post=2&action=edit (does not work)

instead of

example.com/bobstrucks/wp-admin/post.php?post=2&action=edit

I've tried all the WordPress functions to get the full url needed (example.com/bobstrucs/url-to-redirect-to) but have not succeeded.

I'm trying a rather hackish solution where I get the user ID form the logged in user, and get all the blogs the user has (= just one, "Bobs Trucks"):

function admin_default_page() {
    global $current_user;
    get_currentuserinfo();
    $blogs = get_blogs_of_user( $current_user->ID);
    foreach($blogs as $blog) { $userblog = $blog->siteurl; }
    return $userblog .'/wp-admin/post.php?post=2&action=edit';
}

add_filter('login_redirect', 'admin_default_page');

But this one has the problem of not working the first time user logs in.

Thank you very much!

Its an array with an object inside it. Quick question, whats the user id in that example? — Darren
echo $current_user->ID; ends up as "37". Was this what you meant? How can I access the ["siteurl"] (key..?) of this object inside the array? — Jonathan
You could use a foreach($blogs as $blog) { $userblog = $blog->siteurl; } then check if $userblog is correct. — Darren
im sure theres a better alternative than looping but that should work for now provided the user only ever has one blog. Will find something when i can get to the computer :-) — Darren
Ok. Although the loop-solution was correct here seems to be a problem not knowing the necessary information early enough. Since the function gets triggered when user clicks "log in" apparently we don't know the $userblog etc. When user is logged in, the function works but not on the firts time when users loggs in. — Jonathan

Try something like this:

function admin_default_page() {
    if ( is_user_logged_in() && is_admin() ) {
        $blog_id = get_current_blog_id();
        $blog = get_blog_details( array( 'blog_id' => $blog_id ) );
        $location = '/' . $blog->blogname . '/wp-admin/post.php?post=2&action=edit';
        wp_redirect( $location );
        exit;
    }
}
add_filter( 'login_redirect', 'admin_default_page' );
