我有一个带有名称仪表板的PHP CodeIgniter控制器，该控制器位于管理员命名文件夹中，如何使用URL访问该控制器

Question

我有一个带有名称仪表板的PHP CodeIgniter控制器，并且该控制器位于管理员命名文件夹中，我尝试使用url =＆gt;＆＃39; admin / dashboard＆＃39;登录管理仪表板。但它没有显示任何内容并将我重定向到登录页面。

 class Dashboard extends Admin_Controller {

    public function __construct() {

        parent::__construct();
        $this->load->model('admin_model');
    }

    public function index() {

        $data['title'] = "Care Your Car";
        $employee_id = $this->session->userdata('employee_id');
        //total employee count
        $this->admin_model->_table_name = "tbl_employee"; //table name
        $this->admin_model->_order_by = "employee_id"; // order by
        $data['employee'] = $this->admin_model->get_by(array('status' => 1)); // get resutl
        $data['total_employee'] = count($this->admin_model->get()); // get resutl

        $data['subview'] = $this->load->view('admin/main_content', $data, TRUE);
        $this->load->view('admin/_layout_main', $data);
    }

登录模型

<?php

class Login_Model extends MY_Model {

    protected $_table_name;
    protected $_order_by;
    public $rules = array(

            $this->session->set_userdata($data);

登录控制器

class Login extends MY_Controller {

    $this->load->model('admin_model');
}

public function index() {

    $this->login_model->loggedin() == FALSE || redirect($dashboard);

    $this->form_validation->set_rules($rules);
    if ($this->form_validation->run() == TRUE) {
        // We can login and redirect
        if ($this->login_model->login() == TRUE) {
            redirect($dashboard);
        } else {
            $this->session->set_flashdata('error', 'Username / Password combination does not exist');
            redirect('login', 'refresh');
        }
    }
    $data['title'] = "User Login";
    $data['subview'] = $this->load->view('login', $data, TRUE);
    $this->load->view('login', $data);
