我不能在Codeigniter中使用Cookie

Question

我想在Codeigniter中使用Cookie保持登錄狀態，但我無法在Codeigniter中設置Cookie。這是我在Controller中的代碼。當我在登錄表單中單擊提交按鈕時，它會調用chk_login（）函數來檢查數據庫中的用戶名和密碼。之後，它將轉到此行回顯「您沒有登錄」而已。如何在Codeigniter中使用cookie。

<?php 
class Login extends CI_Controller 
{ 

    public function __construct() 
    { 
     parent::__construct(); 
       $this->load->helper('cookie'); 
    } 

    function index() 
    { 
     redirect('login/form_login'); 
    } 

    function form_login() 
    { 
     $data['title'] = 'Login'; 
     $this->load->view('form_login_view', $data); 
    } 

    function goto_test() 
    { 
      if($this->input->cookie('login')){ 
       echo "You are logged in"; 
      } 
      else{ 

       echo "You are not log in"; // It show string in this line every time. that mean cookie not set yet. how to use cookie in Codeigniter. 
      } 
    } 


function chk_login() 
{ 
$this->load->model('login_model', 'login'); 
$this->login->username = $this->input->post('username'); 
$this->login->password = $this->input->post('password'); 

$user_login = $this->login->get_by_user_pass(); 

     if($user_login==null){ 
       $data['errors'] = 'Not found Username.<br />'; 
       $this->load->view('form_login_view', $data); 

    }else{ 

     // I set directed data in cookie but I can't get this cookie in goto_test(). 

     $this->input->set_cookie(array(
           'login'=>TRUE, 
       'username'=>"aaa", 
       'password'=>"123", 
       'status'=>"user")); 


      redirect('login/goto_test'); // Go to function goto_test in this class 
    } 
} 

} 
?> 

我嘗試使用此代碼顯示它布爾（假）測試。

$cookie = array(
      'name' => 'test_cookie', 
      'value' => 'test', 
      'domain' => '/', 
      'secure' => TRUE 
     ); 

$this->input->set_cookie($cookie); 

var_dump($this->input->cookie('name'));

現在我知道了。我不能像這樣設置cookie。我有2種設置cookie的方法。

1.

$cookies = array(
     array(
      'name' => 'login', 
      'value' => true, 
      'domain' => '/', 
      'secure' => true 
    ), 
     array(
      'name' => 'username', 
      'value' => 'aaa', 
      'domain' => '/', 
      'secure' => true 
    ), 
     array(
      'name' => 'password', 
      'value' => '123', 
      'domain' => '/', 
      'secure' => true 
    ) 
); 

foreach($cookie in $cookies){ 
     $this->input->set_cookie($cookie); 
} 

2.

setcookie('login', true); 
setcookie('username','aaa'); 
setcookie('password','123'); 

該Cookie不能設置這樣。

$cookie = array(
      'login' => TRUE, 
      'username' => 'aaa', 
      'password' => '123' 
     ); 

$this->input->set_cookie($cookie);
