電話部件數據對用戶數據（）的非對象上

Question

我的非對象

在得到錯誤

電話部件數據對用戶數據（）當我設置Session$this->session->userdata('userName', $userName);

登錄控制器

<?php 
    class loginController extends CI_Controller { 
     function __construct() { 
      parent::__construct(); 
      $this->load->library('session'); 
     } 
     public function login() { 
      $this->load->View("template/header"); 
      $this->load->View("login_view"); 
     } 
     public function AuthenticateUser() { 
      //Is the UserName and Password values retrieved? 
      if(isset($_POST['userName']) && isset($_POST['password'])) { 
       $this->load->library("UserFactory"); 

       $userName = addslashes($_POST['userName']); 
       $password = addslashes($_POST['password']); 

       //Get User details based on UserName and Password 
       $data = array(
        "users" => $this->userfactory->checkLogin($userName, $password) 
       ); 
       if($data["users"] != null) {      
        $this->session->userdata('userName', $userName); 
       } 
       header('Content-Type: application/json'); 
       echo json_encode($data["users"]); 
      } 
     } 
    } 
?> 

任何想法爲什麼發生這種情況？

Answer 1

$this->session->userdata() 

此用於從會話檢索數據。

到組會議在這裏

if($data["users"] != null) {      
    $this->session->userdata('userName', $userName); # retrieving data 
} 

您試圖從會話訪問數據使用本

$this->session->set_userdata('some_name', 'some_value'); 

---

錯誤的參數沒有設置它

確保已加載$this->load->library('session');

Answer 2

變化

if($data["users"] != null) {      
        $this->session->userdata('userName', $userName); 
       } 

到

if($data["users"] != null) {      
         $this->session->set_userdata('userName', $userName); 
        }
