Controller.php

    function index(){

    $user_profile = 'user';
    $this->authModel->loggedin() == FALSE || redirect($user_profile);

    $rules = $this->authModel->rules;
    $this->form_validation->set_rules($rules);
    if($this->form_validation->run() == TRUE){
        if($this->authModel->login() == TRUE){
            redirect($user_profile);
        }else{
            $this->session->set_flashdata('error', 'That email/password combination does not exist');
            redirect('signin');

    }
 }

Model.php

    function login(){

    $user = $this->get_by(array(
            'email' => $this->input->post('email', TRUE),
            'password' => $this->hash($this->input->post('password'))
        ), TRUE);

    if(count($user)){
        $data = array(
            'name' => $user->name,
            'email' => $user->email,
            'username' => $user->username,
            'loggedin' => TRUE
        );
        $this->session->set_userdata($data);
        return TRUE;
    }

}

嗯，你需要使用 HTTP_REFERER url。 http Referer url 将用户重定向到上次访问的 url 正如你所说

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

为此，您需要检查上次访问的 url 参见代码示例。

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