well you need use HTTP_REFERER url. http Referer url redirect user to last visited url as you say

E.g: Member is reading a news at this URL domain.com/article/news-18565 once he click the login button then how to get currenturl() before going to domain.com/login and after login member should go to domain.com/article/news-18565

For this you need check the last visited url see in code example.

$this->session->set_userdata($data);
if(!empty($_SERVER['HTTP_REFERER'])){
    redirect($_SERVER['HTTP_REFERER']);
} else {
   // add here the default url for example dashboard url
}

Hope it's help you if you have any question let me know
