示例我有一个名为

发生这种情况是因为您没有从当前页面重定向。您只是从

users/add

加载“users”视图

这样想：您所在的页面是

users/add

。此页面显示的内容由您加载的视图决定。因此，即使您加载了

user

视图，您仍然处于

users/add

页面

如果您想重定向，而不是

$this->load->view('dashboard/users',$data);

你需要做什么

redirect(site_url('users')); //or whatever your controller is called

但是，在后一种情况下，不能像加载视图时那样传递数据。如果要在重定向后保留数据，则需要将其存储在会话中

因此，在上面的代码中，创建$data['message']，将其添加到会话中：

$this->session->set_userdata('message',$data['message']);

重定向时，在另一个控制器上检索消息，并将其从会话中删除：

$message = $this->session->userdata('message');

if ($message === FALSE) {
   // message was not present in session
   $message = '';
} else {
    $this->session->unset_userdata('message');
}

编辑

在编辑中，在

用户

控制器中，您正在从会话中提取消息。但是，它对视图不可用。你还需要把它传下去

$message = $this->session->userdata('message');

if($message === FALSE)
{
    $message='';
} else {
    $this->session->unset_userdata('message');
}

//at this point, message is only available to the controller
// lets send it to the view

$data['message'] = $message;
$this->load->view('yourView',$data);

这是因为您没有从当前页面重定向。您只是从

users/add
