Codeigniter:重定向和加载视图之间的flash数据 - Codeigniter : flashdata between redirect and loading view

Codeigniter : flashdata between redirect and loading view

控制器内注册

    function signup() { 
     if('user already exists') {
     $this->session->flashdata('flsh_msg', 'You have already signed up using goole. you will be redirected to home page.');
    redirect('signup/signup/show_message'); 
     }
 }

在同一控制器中显示消息，只是为了显示视图

 function show_message()
  {
      $this->load->view('header/header');
      $this->load->view('signup/signup_message');
      $this->load->view('footer/footer');
  }

视图文件：

<div class="alert alert-success">
    <?php echo $this->session->flashdata('flsh_msg'); ?>
</div>

我无法显示"你已经使用谷歌注册了。你将被重定向到主页。"查看消息时，我已经测试了keep_flashdata和set_flashdata。

有其他方法可以做到这一点吗？如何在重定向和调用视图之间传递flash消息

控制器变更：

$this->session->set_flashdata('flsh_msg', 'You have already signed up using goole. you will be redirected to home page.');

视图原样：

<?php echo $this->session->flashdata('flsh_msg'); ?>

希望这对你有帮助。谢谢

试试这个。

function signup() { 
    if('user already exists') {
       $this->session->set_flashdata('flsh_msg', 'You have already signed up using goole. you will be redirected to home page.');
          redirect('signup/signup/show_message'); 
    }
}

flashdata的设置功能是set_flashdata，而不仅仅是flashdata。。只有flashdata（"flsh_msg"）会获得该字符串，但是set_flashdata设置了它；）

//Controller
$this->session->set_flashdata('flsh_msg', 'You have already signed up using goole. you will be redirected to home page.');
redirect('signup/signup/show_message'); 
//View
<?= $this->session->flashdata('flsh_msg'); ?>

$this->session->set_flashdata('flsh_msg', 'You have already signed up using goole. you will be redirected to home page.');
