Codeigniter控制器返回上一页

Question

我想问你怎么能代替$ this-> load-> view('some_view.php')在控制器代码的末尾,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.

即.

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');
}

Answer 1

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();
}

或直接PHP:

redirect($_SERVER['HTTP_REFERER']);

Answer 2

我在某个帖子上找到了答案.

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());

然后重定向回该页面

$referred_from = $this->session->userdata('referred_from');
redirect($referred_from, 'refresh');
