It's not really a madder of what the user has clicked which anyway you don't have access to since it's on client side (apart using some ajax/javascript). You can know what URI/URL have been requested when you take the decision to redirect the user to the login page.

You have to stock in session ($_SESSION) the requested page. In your login page and when the user manage to login redirect him to the page stocked in session.

for example:

where you take the decision to redirect the user to the login page

if($foobar){
 $_SESSION['requested_page'] = $_SERVER['REQUEST_URI'];
 header('Location: login.php');
 die();
}

on the login page

if($loginOK){
  if(isset($_SESSION['requested_page'])){
    header('Location: ' . $_SESSION['requested_page']);
    die(); 
  }
  header('Location: /index.php');
  die();
}

This is usually handled with $_SERVER['HTTP_REFERER'] which will tell you where the user is coming from. Your log in page can then redirect back to it. (You don't need a session.)
