当我使用set_userdata设置会话并在另一页面检查时，除了userdata之外，所有内容都设置得很好...我使用 var_dump($this->session->all_userdata()); 并且代码说
array（5）{[“session_id”] => string（32）“7195e5aea1695762492bf85d44112120”[“ip_address”] => string（13）“xxx.xxx.x.xxx”[“user_agent”] => string（120 ）“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”[“last_activity”] => int（1414848680）[“user_data”] => string（0）“”}
user_data部分为空 .
这是我的代码（application / controllers / login.php）
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';

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不起作用...）

你在视图或控制器中打印用户数据？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
你可以用
它重定向服务器端
你在加载会话类吗？
$这个 - >负载>库（ ' Session '）;
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 .
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
和'cookie_secure'=只有在存在安全的HTTPS连接时才会设置Cookie .
