我有一个寄存器视图和一个寄存器控制器和一个标题。在标题有一个下拉菜单。
现在，当我从header nav下拉菜单中点击登录按钮时，它不会做任何事情，它只会刷新页面，而不会将我带到登录或注册页面。（这对于我的所有其他视图和控制器都是如此。
即使当我导航到硬编码的URL，如/register/login，它给我404页未找到错误
如何在控制器中正确加载视图，然后从视图中导航到这些视图。
我做错了什么？
下面是我的代码：
控制器为register.register.php：

class Register extends CI_Controller {

    public function __construct()
    {
        parent::__construct();

        $this->load->library(array(
            'session',
            'email',
            'form_validation',
        ));
        $this->load->database();
        $this->load->helper(array(
            'url',
            'string',
        ));
        $this->load->model(array(
            'auth_model',
            'user_model',
            'price_ranges_model',
            'category_model',
            'quote_model',
        ));
    }

    public function index()
    {
        $this->load->view('footer', array(
            'page_title' => 'Register',
        ));
        $this->load->view('register', array(
            'price_ranges' => $this->price_ranges_model->get(),
            'categories' => $this->category_model->get(),
            'delivery_timings' => $this->user_model->_delivery_timings,
        ));
        $this->load->view('footer');
    }

public function login()
    {
        $this->form_validation->set_rules('c_username', 'Username', 'required');
        $this->form_validation->set_rules('c_password', 'Password', 'required');

        if ($this->form_validation->run() == FALSE)
        {
            $this->load->view('header', array(
                'page_title' => 'Register',
            ));
            $this->load->view('register', array(
                'price_ranges' => $this->price_ranges_model->get(),
                'categories' => $this->category_model->get(),
                'delivery_timings' => $this->user_model->_delivery_timings,
            ));
            $this->load->view('footer');
        }

register.php视图：
