在 Codeigniter 会话数据中保存 URL

Question

在用户登录到他们之前所在的页面后，我正在使用 codigniter 重定向用户。

一个示例网址可能是：

http://alpha.scrollr.co/app?tile=TITLE&credit=CREDIT&caption=CAPTION

这是保存网址的代码

$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

 $this->session->set_userdata('redirect', $actual_link);

这用于在他们登录后检索它：

$actual_link = $this->session->userdata('redirect');

但是我无法检索到 actual_link 我在 url 中有多个 GET 参数。

任何想法

Answer 1

没有必要非常聪明。 Codeigniter 已经非常聪明了；

就这样吧：

<?php
/**
 * set session variable 'redirect'
 * with URL and query string
 */
$this->session->set_userdata ( 'redirect', current_url () . '?'. $this->input->server ( 'QUERY_STRING' ) );

/**
 * get session variable 'redirect'
 * with URL and query <string></string>
 * and redirect to user
 */
redirect ( $this->session->userdata ( 'redirect' ) );

/*
If URL is: 
http://localhost/development/ci-admin-with-template/index.php?test=pass&user=valid
User will Redirect on: 
http://localhost/development/ci-admin-with-template/index.php?test=pass&user=valid

If URL is: 
http://localhost/development/ci-admin-with-template/?test=pass&user=valid
User will Redirect on: 
http://localhost/development/ci-admin-with-template/index.php?test=pass&user=valid
*/
?>

如何将 get 变量存储到会话中。

像这样：

$domain = current_url(); //http://alpha.scrollr.co/app
$this->session->set_userdata('tile'   , 'TITLE'); //stores the title
$this->session->set_userdata('credit' , 'CREDIT'); //stores the credit
$this->session->set_userdata('caption', 'CAPTION'); //stores the caption

然后你可以UNSET他们之后。

$this->session->unset_userdata('tile');
$this->session->unset_userdata('credit');
$this->session->unset_userdata('caption');

将get变量存储到会话中怎么样？

像这样：

$domain = current_url(); //http://alpha.scrollr.co/app
$this->session->set_userdata('tile'   , 'TITLE'); //stores the title
$this->session->set_userdata('credit' , 'CREDIT'); //stores the credit
$this->session->set_userdata('caption', 'CAPTION'); //stores the caption

然后你可以UNSET他们之后。

$this->session->unset_userdata('tile');
$this->session->unset_userdata('credit');
$this->session->unset_userdata('caption');
