Question

我想从数据库中获取每个用户的登录和注销条目。现在可以通过传递用户的emp_id来获取登录或注销。因此，无论我在哪个用户中传递条件，都会获取该用户的登录和注销数组。

现在我有多个用户，因此想要获取每个用户的登录注销条目。所以我用于每个循环并循环用户emp_id。并将其传递给我的模型方法，以便我可以传递所有emp_id并获取每个人的登录和注销详细信息。

现在这就是我在控制器中做的事情：

 $users = $this->data['users'] = $this->user_m->get();


        foreach ($users as $user) 
        { 
            $emp_id = $user->emp_id; 
            $all_login = $this->data['attendances_logins'] = $this->attendance_m->all_login($emp_id); 
            $all_logout = $this->data['attendances_logouts'] = $this->attendance_m->all_logout($emp_id); 

        }

        $this->data['subview'] = 'admin/dashboard/index';
        $this->load->view('admin/_layout_main',$this->data);

因此，如果我var_dump($users);，我将获得所有用户的所有数组。如果我var_dump($all_login/all_logout);，我将获得每个用户的登录入口和注销条目。

现在在我看来，如果我这样做 var_dump($attendances_logins);我只是获取最后一位用户的数据。为什么它不像我进入控制器那样打印每个用户的登录和注销条目？

这是我的代码，用于获取我已经通过$emp_id的登录和注销条目，因此它返回每个用户的登录和注销：

public function all_login($emp_id)
{

    $startDate = new DateTime("first day of last month");
    $endDate = new DateTime("last day of last month");
    $this->db->select('*');
    $this->db->from('daily_data2');
    $this->db->where('users.emp_id',$emp_id);
    $this->db->where('entry >','100');
    $this->db->where("date(date_data) BETWEEN '" . $startDate->format( 'Y-m-d' ) . "' AND '" . $endDate->format( 'Y-m-d') . "' ");                                                  
    $this->db->order_by("date_data","ASC");
    $this->db->join('users', 'users.emp_id = daily_data2.emp_id','inner');     
    $query = $this->db->get(); 
    $res   = $query->result();        
    return $res;

}




public function all_logout($emp_id)
{


      $startDate = new DateTime("first day of last month");
      $endDate = new DateTime("last day of last month");
      $this->db->select('*');
      $this->db->from('daily_data2');
      $this->db->where('users.emp_id',$emp_id);
      $this->db->where('entry <','100');
      $this->db->where("date(date_data) BETWEEN '" . $startDate->format( 'Y-m-d' ) . "' AND '" . $endDate->format( 'Y-m-d') . "' ");                                                     
      $this->db->order_by("date_data","ASC");
      $this->db->join('users', 'users.emp_id = daily_data2.emp_id','inner');
      $query = $this->db->get(); 
      $res   = $query->result();        
      return $res;


}

Answer 1

尝试这样的事情

foreach ($users as $user) 
{ 
    $emp_id = $user['emp_id']; 
    $attendances_logins = $this->attendance_m->all_login($emp_id); 
    $attendances_logouts = $this->attendance_m->all_logout($emp_id); 

    $login_logout[] = array(
        'userId' => $emp_id,
        'login' => $attendances_logins, # Count number only 
        'logout' => $attendances_logouts # Count number only 
        );
}

$data['login'] = $login_logout
// load view

Answer 2

我相信你的PHP代码有错误：

    $all_login = $this->data['attendances_logins'] = $this->attendance_m->all_login($emp_id); 
    $all_logout = $this->data['attendances_logouts'] = $this->attendance_m->all_logout($emp_id);

应该像这样设置：

$this->data['attendances_logins'] = array();
$this->data['attendances_logouts'] = array();

        foreach ($users as $user) 
        { 
            $this->data['attendances_logins']["$emp_id"] = $this->attendance_m->all_login($emp_id); 
            $this->data['attendances_logouts']["$emp_id"] = $this->attendance_m->all_logout($emp_id); 
        }

数据没有从控制器发送到codeigniter中查看？
