How to redirect user "back two pages" after login

Question

My users are only able to log in on the mysite.com/user page (I don't use any of the login blocks). How can I redirect those users to their location "two pages ago"? For example, they might visit the about us page, then click login (taking them to the /user page). After they complete their login, I would like for them to be redirected back to the about us page.

I currently have it set to redirect to the previous page after login, but that will always be the "user" page, which is not particularly useful in this instance.

Thanks!

Answer 1

Append

?destination=[PATH]

to your login link.

You can do this with the Menu Token Module

Answer 2

If you have put the user/login in a menu you can you this theme function in your template.php file to override the links to add the destination parameter, here is a sample code.

function yourthemename_menu_link(array $variables) {
  $element = $variables['element'];
  $sub_menu = '';

  if ($element['#below']) {
    $sub_menu = drupal_render($element['#below']);
  }
  // Add destination query parameter for login, logout and register menus
  if (in_array($element['#href'], array('user/login', 'user/register'))) {
    $element['#localized_options']['query'] = array('destination' => current_path());
  }
  $output = l($element['#title'], $element['#href'], $element['#localized_options']);
  return '<li' . drupal_attributes($element['#attributes']) . '>' . $output . $sub_menu . "</li>\n";
}
