Question

当我使用set_userdata设置会话并在另一页检查时，除了userdata之外，所有内容都设置得很好... 我使用var_dump($this->session->all_userdata());，代码说

array（5）{[＆＃34; session_id＆＃34;] =＆gt; string（32）＆＃34; 7195e5aea1695762492bf85d44112120＆＃34; [＆＃34; IP_ADDRESS＆＃34;] =＆GT; string（13）＆＃34; xxx.xxx.x.xxx＆＃34; [＆＃34; USER_AGENT＆＃34;] =＆GT; string（120）＆＃34; Mozilla / 5.0（Macintosh; Intel Mac OS X 10_10_0）AppleWebKit / 537.36（KHTML，类似Gecko）Chrome / 38.0.2125.104 Safari / 537.3＆＃34; [＆＃34; last_activity＆＃34;] =＆GT; int（1414848680）[＆＃34; user_data＆＃34;] =＆gt; string（0）＆＃34;＆＃34; }

user_data部分为空。

这是我的代码（应用/控制器/ login.php中）

class Login extends CI_Controller {
    function index(){
        $this->load->model('Join_model');
        $this->load->view('head');
        if($this->input->post('id')){
            $data = $this->Join_model->gets(array(
               'table'=>'acc_wait_tb',
               'id'=>$this->input->post('id'),
               'password'=>$this->input->post('password'),
            ));
            if($data == true){
                $dd = $this->db->get_where('acc_wait_tb', array('id'=>$this->input->post('id')))->row();
                $new_data = array(
                    'user_id'=>$dd->id,
                    'name'=>$dd->name,
                    'email'=>$dd->email,
                );
                $this->session->set_userdata($new_data);
                echo "<script>
                    location.href='/index.php/main';
                    </script>";
            }else if($data == false){
                echo "<script>alert('Login Fail.');</script>";
                $this->load->view('log_main');
                $this->load->view('footer');
            }
        }else{
            $this->load->view('log_main');
            $this->load->view('footer');
        }
    }
}

和application / views / nav.php

var_dump($data);
$user_id = $this->session->userdata('user_id');?>
<?php if($user_id != ""): ?>
<p class="navbar-text pull-right" style="margin-right:30px;">Hi,
  <a class="navbar-link" href=""><?=$this->session->userdata('name')?></a>
</p>
<?endif;?>

和application / config / config.php

$config['encryption_key'] = 'asdfqwerertydfghcvbnsdfgqwerxcvb';

/*

$config['cookie_prefix']  = "";

请！帮我！这个错误让我发疯！请...！（我尝试在控制器中解决此调用userdata并使用$this->load->view('nav.php',$data);将数据发送到视图但是它没有工作......）

Answer 1

您是在视图或控制器中打印用户数据吗？尝试在控制器中打印它。我觉得在视图中$ this与控制器中的不同可能是导致问题的原因。您可能必须将$ new_data传递给视图。另外代替

echo "<script>
location.href='/index.php/main';
</script>";

你可以使用

redirect(main);

重定向服务器端

Answer 2

您正在加载会话类吗？

$这 - ＆GT;负载＆GT;库（＆＃39;会话＆＃39）;

我总是在自动加载中设置会话。但是当我忘记我遇到这种问题时。

Answer 3

我可能错了，因为我不知道你的代码在哪里运行，但如果你是localhost，你可能会发现浏览器拒绝你的cookie。你也有

$config['cookie_secure']  = TRUE

和＆＃39; cookie_secure＆＃39; =只有存在安全的HTTPS连接时才会设置Cookie。

Codeigniter userdata会话为空
