重定向到上一页时如何发送变量数据 [英] How to send variable data when redirecting to previous page

问题描述

完成特定任务后，我使用以下代码将用户重定向到上一页。

I am using the following codes to redirect my user to previous page after a particular task is done.

        if (isset($_SERVER['HTTP_REFERER']))
         {
         $this->session->set_userdata('previous_page', $_SERVER['HTTP_REFERER']);
         }
         else
         {
         $this->session->set_userdata('previous_page', base_url());
         }

我在控制器中使用以上代码，在另一个控制器中使用以下代码。 。

The above code I use in a controller and the following code in another controller..

    .... some other stuffs... I am updating database values here....

        $this->db->where('t_expenseid', $t_expenseid);
        query=$this->db->update('teacherexpense', $data); 


        redirect($this->session->userdata('previous_page'));

上面的代码工作正常，但我面临的问题是我想发送成功消息重定向，以便在上一页加载时弹出一条成功消息（我已经为此使用了jquery）。为此，我在重定向上方添加了以下代码，但我不知道如何与重定向一起发送$ data或消息。如果我能够发送它，如何在上一页的控制器中检索值。

The above code is working fine but the problem I am facing is I want to send a success message with the redirect so that when the previous page loads a success message pops up (I already have jquery for that). And for this I added the following code above the redirect, but I don't know how to send the $data or the message along with the redirect. And if I am able send it how to retrieve the value in the controller of the previous page.

 $data['msg']='Information Has been Successfully Inserted'; 

能否请您告诉我如何发送然后取回它？

Could you please tell me how to send it and then retrieve it?

谢谢：）

推荐答案

您可以使用CI的set_flashdata。该消息只能使用一次刷新页面消息变为空白后。

You can use set_flashdata of CI.You can use only once that message after refresh page message goes blank.

  $this->session->set_flashdata('message', 'Authentication failed');

  redirect(site_url('message/index/'), 'refresh'); 

在该页面上，您可以通过

And on that page you can catch this message by

$message = $this->session->flashdata('message').
