Codeigniter Controller return to previous page
提问by luka032
I'd like to ask you how can I instead of $this->load->view('some_view.php') at the end of controller code, return user to page from where he invoked controller method? Simple return statement is not working.
我想问你如何在控制器代码的末尾而不是 $this->load->view('some_view.php') ，将用户返回到他调用控制器方法的页面？简单的 return 语句不起作用。
ie.
IE。
public function someMethod($IDCustomer) {
$this->Some_modal->persist($IDCustomer);
// how to return to previous page instead of line after?
// i've used $this->load->view('someView.php');
}

This should help http://www.codeigniter.com/user_guide/libraries/user_agent.html
这应该有助于http://www.codeigniter.com/user_guide/libraries/user_agent.html
$this->load->library('user_agent');
if ($this->agent->is_referral())
{
echo $this->agent->referrer();
}
or straight PHP:
或直接PHP：
redirect($_SERVER['HTTP_REFERER']);

I've found answer on some thread.
我在某个线程上找到了答案。
In the page that you want to go back to you can do:
$this->session->set_userdata('referred_from', current_url());Then redirect back to that page
$referred_from = $this->session->userdata('referred_from'); redirect($referred_from, 'refresh');
在您要返回的页面中，您可以执行以下操作：
$this->session->set_userdata('referred_from', current_url());然后重定向回那个页面
$referred_from = $this->session->userdata('referred_from'); redirect($referred_from, 'refresh');

I've tried header('location:'.$_SERVER['HTTP_REFERER']);and it's working quite well.
我试过了header('location:'.$_SERVER['HTTP_REFERER']);，效果很好。
Just a one-liner plain old PHP code.
只是一个单行普通的旧 PHP 代码。

Use the REDIRECT_QUERY_STRINGalternative of HTTP_REFERRER:
使用以下REDIRECT_QUERY_STRING替代方法HTTP_REFERRER：
// set in session redirect back URL in your common is_logged_in function if user is not logged in
$CI->session->set_userdata('redirect_back', $_SERVER['REDIRECT_QUERY_STRING']);
// below code user after successful login in auth.php library
if($this->ci->session->userdata('redirect_back')){
$redirectBackUrl = $this->ci->session->userdata('redirect_back');
$this->ci->session->unset_userdata('redirect_back');
redirect(base_url() . $redirectBackUrl);
}
