登录Codeigniter后如何修复页面重定向

Question

我编写了一个可以在我的本地主机上完美运行的代码，但是当应用程序继续循环回到登录页面时，即使使用正确的登录凭据也无法成功登录。

由于该应用程序在本地运行良好，所以我认为我的问题将是php / apache版本或/和配置问题。我在.htaccess文件中尝试了几种设置，但均未成功。该应用程序已使用codeigniter框架版本2.2.0编写。

登录控制器

    function ajax_login()
    {

        $response = array();
        $url = $this->get_url();

        if (strpos($url, 'students')  !== FALSE)
        {

            $mat_no = $_POST["mat_no"];

        }else
        {
            $email = $_POST["email"];
        }

        //Recieving post input of email, password from ajax request
        //$email        = $_POST["email"];
        $password   = $_POST["password"];
        $response['submitted_data'] = $_POST;
        //$login_status = $this->validate_login_student( $mat_no ,  $password );
        //Validating login
        $url = $this->get_url();
        if (strpos($url, 'students') !== FALSE)
        {
            $login_status = $this->validate_login_student( $mat_no ,  $password );
        }else
        {
            $login_status = $this->validate_login( $email ,  $password );
        }


        $response['login_status'] = $login_status;
        if ($login_status == 'success') {

            $response['redirect_url'] = '';

        }

        //Replying ajax request with validation response
        echo json_encode($response);
    }

  function logout()
    {
        $acctype = $this->session->userdata('login_type');
        if ($acctype == 'admin')
        {
            $acctype = 'webadmin';
        }elseif ($acctype == "student"){
            $acctype = 'students';
        }elseif ($acctype == "teacher"){
            $acctype = 'teachers';
        }
        elseif ($acctype == "parent"){
            $acctype = 'parents';
        }
        $this->session->unset_userdata();
        $this->session->sess_destroy();
        $this->session->set_flashdata('logout_notification', 'logged_out');
        redirect(base_url().$acctype , 'refresh');
    }

routes.php

$route['404_override'] = '';

$route['students'] = "login";
$route['teachers'] = "login";
$route['parents'] = "login";
