title: codeigniter - Page with multiple forms
body: <p>I'm new to codeigniter this is my case:
  I have a homepage with a list of items, I can navigate through pagination, but I have in my sidebar a login form, it's possible to return to the same page after try to login in the case that is valid or not with a validation message.
  for the login option I have a controller and login function but I don't know what view load after validation.
  I need to login in any controller and return to the same url.
  thanks</p>
