Question

我的登录页面：

这是我的登录页面，在该页面中，我仅验证用户名和密码。现在，我要选择“公司名称和年份”作为输入，但不能简单地验证输入值。我的问题是我想在顶部的仪表板页面上显示公司名称和年份。

我如何在仪表板中显示值

 function index()
 {
   //This method will have the credentials validation
   $this->load->library('form_validation');

   $this->form_validation->set_rules('username', 'Username', 'trim|required');
   $this->form_validation->set_rules('password', 'Password', 'trim|required|callback_check_database');

   if($this->form_validation->run() == FALSE)
   {
     //Field validation failed.  User redirected to login page
    $query = $this->db->get('company_name');    
    $data['PName']=$query->result_array();

     $this->load->view('admin/login',$data);
   }
   else
   {
     //Go to private area
    redirect('Dashboard', 'refresh');
    //  $this->load->view('Dashboard');
   }

 }

 function check_database($password)
 {
   //Field validation succeeded.  Validate against database
   $username = $this->input->post('username');
   $password = $this->input->post('password');
   $year= $this->input->post('Year');

   //query the database
   $result = $this->User_model->login($username, $password);

   if($result)
   {
     $sess_array = array();
     foreach($result as $row)
     {
       $sess_array = array(
         'id' => $row->id,
         'username' => $row->username,


       );

       $this->session->set_userdata('logged_in', $sess_array);
     }
     return TRUE;
   }
   else
   {
     $this->form_validation->set_message('check_database', 'Invalid username or passwords');
     return false;
   }
 }

首先将数据存储在会话中，为此，您的索引函数应如下所示：

function index()
 {
       //This method will have the credentials validation
       $this->load->library('form_validation');

       $this->form_validation->set_rules('username', 'Username', 'trim|required');
       $this->form_validation->set_rules('password', 'Password', 'trim|required|callback_check_database');

       if($this->form_validation->run() == FALSE)
       {
         //Field validation failed.  User redirected to login page
        $query = $this->db->get('company_name');    
        $data['PName']=$query->result_array();

         $this->load->view('admin/login',$data);
       }
       else
       {
           $newdata = array(
                   'username'  => $this->input->post('username'),
                   'Year'     => $this->input->post('Year'),
                   'company_name'     => $this->input->post('company_name')
               );
            $this->session->set_userdata($newdata);


            //Go to private area
            redirect('Dashboard', 'refresh');
        //  $this->load->view('Dashboard');
       }

 }

此后，当您重定向到仪表板页面中视图中的仪表板视图文件中时，可以通过执行以下操作来显示数据：

<h1>Company: <?php echo $this->session->userdata('company_name'); ?> </h1>
<h1>User: <?php echo $this->session->userdata('username'); ?> </h1>
<h1>Year: <?php echo $this->session->userdata('Year'); ?> </h1>

尝试在您的登录页面上使用会话因此您可以在登录后显示公司名称和年份

登录页面后如何显示用户详细信息？
