codeigniter离子auth获取用户ID [英] codeigniter ion auth getting user id

问题描述

我需要获取登录的用户的用户ID，以便我可以为该用户运行查询。 Im使用离子auth，应该使用会话还是从db调用它，我应该使用帮助？无论如何，heres我试图做什么：

I need to get the user id of the person logged in, so that i can run a query for that user. Im using ion auth, should i use a session or call it from the db, should i use a helper or not? anyway, heres what im trying to do:

示例：用户登录的工作订单有多少？
查询将是：select * from work_orders WHERE status =1AND userid =％THE LOGGED IN USER

example: how many work orders does logged in user have? query would be: select * from work_orders WHERE status = "1" AND userid = "%THE LOGGED IN USER"

这里是我的控制器，具有获取用户ID代码：

here is my controller, which doesnt have the "get user id" code:

public function index()
{
    $this->load->view('templates/header');
    $data['total_open_wo'] = $this->Home_model->total_open_wo();
    $data['result'] = $this->Home_model->index();
    $this->load->view('home', $data);
    $this->load->view('templates/footer');

}

这里是我的模型：

public function total_open_wo()  {

        $this->db->where('status', "1");
        $this->db->where('tid', "NEED_THE_USER_ID");
        $num = $this->db->count_all_results('work_orders');

        return ($num);
    }

推荐答案

您可以使用离子授权中的 get_user_id（）函数来获取用户ID。在模型中的相关注释中，您需要一个 $ this-> db-> from（）调用来设置表以获取行数。

Provided the user is logged in you can get the user ID by using the get_user_id() function in ion auth. On a related note in your model you need a $this->db->from() call to set the table to fetch the number of rows from.

public function total_open_wo() {
  $userId = $this->ion_auth->get_user_id();
  $this->db->where('status', '1');
  $this->db->where('tid', $userId);
  $this->db->from('work_orders');
  $num = $this->db->count_all_results();

  return $num;
}

使用函数 $ this-> ion_auth- > logged_in（）以确保用户在调用模型函数之前已登录。

Use the function $this->ion_auth->logged_in() to make sure that the user is logged in before calling the model function.
