Question

使用Codeigniter 2.xx，如何在需要新HTTP请求的方法调用之间保留属性值？我试图避免多次获取和设置相同的数据。当前的例子：型号：

class Plan_model extends Ci_model{
     public $plan_id;
     public function __construct()
     {
         parent::construct(); 
     }

     public function set_plan_id($plan_id) 
     {
        $this->plan_id = $plan_id; //Becomes NULL with new http request, want to keep value  
     }
}

控制器：

class Plan extends Ci_controller{

     public function __construct()
     {
        parent::__construct();
        $this->load->model('plan_model');
     }

    public function set_plan_id()
    { 
       $this->plan_model->set_plan_id(3)
       redirect('/plan/get_plan_id');
    }

    public function get_plan_id()
    {
       $plan_id = $this->plan_model->plan_id; //produces NULL, Expecting 3
    }

您可能正在考虑使用会话来定义信息。

$this->session->set_userdata($plan_id);

以下是会话数据的链接：https://ellislab.com/codeigniter/user-guide/libraries/sessions.html
