Question

观点：

<?php
    if($this->input->post('submit'))
    { 
        $username = $this->input->post('username');
        $password = $this->input->post('password');

        $this->db->select('username,password,admin_id');
        $this->db->from('admin');
        $where = "username='$username' and password = '$password'";
        $this->db->where($where);
        $query = $this->db->get();
        $result = $query->row_array();
        $num = $query->num_rows();
        if($num > 0)
        {
            $this->session->set_userdata('admin_id',$result);
            redirect('admin/home');
        }
        else
        {
            echo "<p style='color: red;font-weight: 400;margin-right: 60px;'>Wrong email id or password! </p>";
        }
    }
?>
<form class="form-signin" method="post">
    <input type="text" name="username" id="username" class="form-control" placeholder="username" required autofocus>
    <input type="password" name="password" id="password" class="form-control" placeholder="Password" required>
    <input type="submit" id="submit" name="submit" class="btn btn-lg btn-primary btn-block" value="Sign In">
</form>

controller：admin.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Admin extends CI_Controller {
    function __construct() 
    {
        parent :: __construct();
        $this->load->helper(array('form', 'url', 'captcha', 'email'));
        $this->load->model('ad_data');
    }
    public function home()
    {
        $data['admin_id'] = $this->session->userdata('admin_id');
        print_r($data['admin_id']);
    }
}

在这段代码中我创建了一个简单的登录表单，并希望在我的控制器上设置会话变量值，即在该控制器内部的admin.php我有会话的打印值，但没有从中获取任何内容。我想提一下somthing，即会话值是在localhost上启用但不在godaddy主机上工作我不知道为什么？我该如何解决这个问题？请帮帮我。

谢谢

检查godaddy服务器上的php版本和CI版本。我有同样的错误，发现这个answer

在godaddy服务器上不启用会话值，但在localhost上工作。
