Question

在控制器注册中

    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'); 
     }
 }

在同一个控制器中显示消息，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');
  }

在查看文件中：

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

我无法展示＆＃34;您已经使用goole注册了。您将被重定向到主页。＆＃34;在视图上的消息，我测试了keep_flashdata和set_flashdata。

还有其他方法吗？如何在重定向和调用视图之间传递flash消息

Answer 1

控制器更改：

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

视图就是这样：

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

希望这会对你有所帮助。谢谢！

Answer 2

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，不仅是flashdata ..只有flashdata（“flsh_msg”）会得到那个字符串，但set_flashdata设置它;）

Answer 3

//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'); ?>
