Codeigniter。控制器无法接收会话数据

Question

我将会话成功设置为输出分析器显示会话名称和值。 但是，当我的POST数据控制器不能接收会话数据。 图书馆被加载，$ config ['sess_expire_on_close'] = TRUE我改变了TRUE-FALSE没有任何成功。还尝试了重写代码。 另一个问题，我使用两台电脑，并在Linux机器上我得到错误“标题已发送...”，但在Win机器上我没有收到此消息。如何在Win PC上启用它。通知和警告已启用。

所以......

控制器kmgld：

function authorisation_user() 
    { 
      ...... 
      $data['set_cookie']  = "Surname"; 
      ...... 
      $this->load->view('vheader', $data); 
      $this->load->view('vuser_kmgld'); 
      $this->output->enable_profiler(TRUE); //show me only session name and value which I set 
    } 

查看：

if ($set_cookie!=NULL) 
    { 
     $this->session->set_userdata('surname',$set_cookie); 

    } 
    <!Doctype...> 

    <form action="<?php echo base_url()?>index.php/kmgld/update_kmgld" method="post" name=""> 

又一次控制器kmgld从视图

 function update_kmgld() 
     { 
     ...update DB 
     $test=$this->session->userdata('surname'); 
     echo $test; //it is NULL 
     $this->output->enable_profiler(TRUE); // show me only now session id, ip, user agent 
     } 

Answer 1

删除会话设置和做在控制ller：

function authorisation_user() 
    { 

      $data['set_cookie']  = "Surname"; 

      $this->session->set_userdata('surname',$set_cookie); 
      $this->load->view('vheader', $data);//are you sure here is where $data should go ? 
      $this->load->view('vuser_kmgld');//not $data here? 
      $this->output->enable_profiler(TRUE); //show me only session name and value which I set 
    } 

Answer 2

你必须在控制器中设置userdata，视图是不适合它的地方。所以你可能会做这样的事情在你的控制器：

$surname = "Surname"; 
$this->session->set_userdata('surname',$surname); 
$data['set_cookie'] = $surname; 
... 
$this->load->view('vheader', $data); 

不知道你是否自动加载Session库。否则你必须在你需要的每个函数中加载它。

查看vauthorisation：

<?php 
    $surname_value = $this->session->userdata('surname'); 
?> 

    <?php 
    if ($flag =="wrong") 
{ 
    echo "...Bad very bad. Try use another language "; 
} 


?> 

HTML： 形式方法= “邮报” 行动= “authorisation_user” 输入类型= “文本” 名称= “姓”

查看vheader：

<?php 
if ($set_cookie!=NULL) 
{ 
    $this->session->set_userdata('surname',$set_cookie); 
    echo "cookie set".$set_cookie; 

} 


?> 

查看vuser_kmgld：

HTML ： form action =“update_kmgld” inputs name = day，name = mon，name = year，name = spd_before ... etc。经过php代码：

if (isset($user_id[0]->user_id)) 
    { 
    foreach ($query as $row) 
{ 
    echo "<tr> 
           <td>".(isset($row->date)? date("d.m.Y",  strtotime($row->date)): "")."</td>
