【问题描述】:
当我使用 set_userdata 设置会话并检查其他页面时,除了 userdata 之外,一切都设置得很好......
我使用var_dump($this->session->all_userdata()); 和代码说
array(5) { ["session_id"]=> 字符串(32) "7195e5aea1695762492bf85d44112120" ["ip_address"]=> 字符串(13) "xxx.xxx.x.xxx" ["user_agent"]=> 字符串(120) "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.104 Safari/537.3" ["last_activity"]=> int(1414848680) ["user_data"] => 字符串(0) "" }
user_data 部分为空。
这是我的代码 (应用程序/控制器/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');
$this->load->view('footer');
}
}
}
和应用程序/views/nav.php
var_dump($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;?>
和应用程序/config/config.php
$config['encryption_key'] = 'asdfqwerertydfghcvbnsdfgqwerxcvb';

请!帮我!这个错误让我抓狂!请...!
(我尝试在控制器中解决这个调用 userdata 并使用 $this->load->view('nav.php',$data); 将数据发送到视图但它不起作用......)
【问题讨论】:
-
我已经测试了你的代码并且没问题。尝试调试它有什么问题。write var_dump($this->session->userdata); die() 在 $this->session->set_userdata($new_data) 行之后;并检查它是否设置了您的会话数据。如果没有,那么问题可能出在您查询它没有获取数据的位置。
-
我也面临这个问题,在我成功登录后的情况下,我在会话中设置 user_data 并在回显整个会话数据之后,这很好,但在重新加载页面后 user_data 变量显示空值.. ..您对此有任何解决方案吗....?
