php - Codeigniter Controller 返回上一页

Question

我想问你，我怎样才能代替 Controller 代码末尾的 $this->load->view('some_view.php')，让用户返回到他调用 Controller 方法的页面？简单的返回语句不起作用。

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');
}

这应该有帮助 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']);
