Codeigniter會話在當地工作正常，但不能在Godaddy上工作

Question

我開發了關於在我的本地（WAMP服務器）上正常工作的php框架（Codeigniter）的網站。當我將它上傳到Godaddy主機時，它無法登錄到網站。以下是登錄類功能。

public function index() 
{ 

    if ($this->session->userdata('admin_login') == 1) 
     redirect(base_url() . 'index.php?admin/dashboard', 'refresh'); 


    $this->load->view('backend/login'); 
} 


function ajax() 
{ 
    $response = array(); 


    $email  = $_POST["email"]; 
    $password = $_POST["password"]; 
    $response['submitted_data'] = $_POST;  


    $login_status = $this->validate_login($email , sha1($password)); 
    $response['login_status'] = $login_status; 
    if ($login_status == 'success') { 
     $response['redirect_url'] = ''; 
    } 

    echo json_encode($response); 
} 


function validate_login($email = '' , $password = '') 
{ 
    $credential = array( 'email' => $email , 'password' => $password); 

    $query = $this->db->get_where('users' , $credential); 

    if ($query->num_rows() > 0) { 
     $row = $query->row(); 
      $this->session->set_userdata('admin_login', '1'); 
      $this->session->set_userdata('admin_id', $row->id); 
      $this->session->set_userdata('name', $row->name); 
      $this->session->set_userdata('login_type', 'admin'); 

      return 'success'; 
    } 

    return 'invalid'; 
} 

我意識到這 - $>會話級> set_userdata（）方法是在GoDaddy的工作。

Answer 1

Please try this 
Please add session library just like below. 

$this->load->library('session'); 
if ($this->session->userdata('admin_login') == 1) 
     redirect(base_url() . 'index.php?admin/dashboard', 'refresh'); 



    $this->load->view('backend/login'); 

Answer 2

首先加載Session庫 然後 而不是使用此

if ($this->session->userdata('admin_login') == 1) 

使用此

if ($this->session->userdata['admin_login'] == 1) 

檢查它是否是工作或沒有

Answer 3

嘗試一些替代品的可能工作： 更改這些l在application/config/config.php

$config['sess_cookie_name'] = 'cisession';  //remove(underscore) 
$config['cookie_domain'] = ".example.com"; //make it site wide valid 

Answer 4

INES您可以將多個會話變量存儲在陣列

function validate_login($email = '', $password = '') { 
    $credential = array('email' => $email, 'password' => $password); 

    $query = $this->db->get_where('users', $credential); 

    if ($query->num_rows() > 0) { 
     $row = $query->row(); 
     $sess_array = array(
       'admin_login' => 1, 
       'admin_id' => $row->id, 
       'name', $row->name, 
       'login_type', 'admin' 
      ); 

     $this->session->set_userdata('logged_in', $sess_array); 
    } 
    return 'invalid'; 
} 

你需要在你的構造

public function __construct() 
{ 
    parent::__construct(); /* necessary! */ 

    /* load model for calls to database */ 
    $this->load->library('session');// load session library 
    $this->load->helper('url'); 
} 

上傳session library在你index你要檢查用戶logged_in是是否設置

public function index() 
{ 
     if ($this->session->userdata('logged_in')){// check session set or not 
     redirect(base_url() . 'index.php?admin/dashboard', 'refresh'); 
     $this->load->view('backend/login'); 
     } 
} 

Answer 5

好的，我假設你使用CI2，因爲你在一個不存在的會話變量上獲得FALSE。 CI會話使用Cookie和/或數據庫，具體取決於您的配置。你的配置文件有哪些cookie設置？

你應該注意這些設置：

$config['cookie_prefix'] = ""; 
$config['cookie_domain'] = ""; 
$config['cookie_path']  = "/"; 
$config['cookie_secure'] = FALSE; 

和這些的（在這兩種情況下顯示默認配置）：

$config['sess_cookie_name']  = 'ci_session'; 
$config['sess_expiration']  = 7200; 
$config['sess_expire_on_close'] = FALSE; 
$config['sess_encrypt_cookie'] = FALSE; 
$config['sess_use_database'] = FALSE; 
$config['sess_table_name']  = 'ci_sessions'; 
$config['sess_match_ip']  = FALSE; 
$config['sess_match_useragent'] = TRUE; 
$config['sess_time_to_update'] = 300; 

是您的網站託管在一個子？ Cookie通過標題設置。是否有任何輸出在您的Cookie設置之前生成？將您的log_threshold設置爲2，以便您可以看到生成的最終錯誤和調試消息。

$config['log_threshold'] = 2; 

您是否設置了密碼？

$config['encryption_key'] = '[there-must-be-something-here]'; 

Answer 6

我嘗試了所有在這裏提到的答案，但沒有爲我的問題工作。

我的問題是

$this->session->userdata('admin_login')返回false。

Finaly我試過數據庫來存儲會話。

$config['sess_use_database'] = TRUE; 
$config['sess_table_name']  = 'ci_sessions'; 

而創建ci_sessions表。

CREATE TABLE IF NOT EXISTS `ci_sessions` (
    session_id varchar(40) DEFAULT '0' NOT NULL, 
    ip_address varchar(45) DEFAULT '0' NOT NULL, 
    user_agent varchar(120) NOT NULL, 
    last_activity int(10) unsigned DEFAULT 0 NOT NULL, 
    user_data text NOT NULL, 
    PRIMARY KEY (session_id), 
    KEY `last_activity_idx` (`last_activity`) 
); 

然後正常工作

Answer 7

這應該是你的Config配置

$config['sess_cookie_name']  = 'cisession'; 
$config['sess_expiration']  = 7200; 
$config['sess_expire_on_close'] = TRUE; 
$config['sess_encrypt_cookie'] = TRUE; 
$config['sess_use_database'] = TRUE; 
$config['sess_table_name']  = 'ci_sessions'; 
$config['sess_match_ip']  = FALSE; 
$config['sess_match_useragent'] = TRUE; 
$config['sess_time_to_update'] = 300; 

而且在模型中必須設置會話。

public function login() 
{ 
    $user = $this->get_by(array(
     'email' => $this->input->post('email'), 
     'password' => $this->hash($this->input->post('password')), 

    ), TRUE); 

    if (count($user)) { 
     // Log in user 
     $data = array(
      'name' => $user->name, 
      'email' => $user->email, 
      'gender'=>$user->gender, 
      'user_num'=>$user->user_num,  
      'id' => $user->id, 
      'loggedin' => TRUE, 
      'balance' =>$user->balance, 
      'usertype' =>'admin', 
     ); 
     $this->session->set_userdata($data); 
    } 
} 

這個工作對我來說:)
