使用会话 ID 过滤数据

Question

我想使用会话 ID 过滤数据。有一个如下表。

id   | user_id | plan
  1  | 1       |.sjhsjh.jpg
  2  | 2       |bchdj.jpg

我想根据登录 user.user id 过滤那个数据库值，它是用户表的外键。以前过滤过，现在不行了。

型号

function get_plan(){

$this->db->select("floor_plan.id,floor_plan.image"); 
$this->db->where("user_id",$this->session->userdata['logged_in']['id']); 
$this->db->from('floor_plan');
$query = $this->db->get();
return $query->result();

会话

<?php
if (isset($this->session->userdata['logged_in'])) {
$firstname = ($this->session->userdata['logged_in']['firstname']);
$email = ($this->session->userdata['logged_in']['email']);
$id = ($this->session->userdata['logged_in']['id']);
} else {
header("location: login");
}

改变模型如下。

    function get_plan(){
       $userdata=$this->session->userdata('logged_in');
       $this->db->select("floor_plan.id,floor_plan.image"); 
         $this->db->where("user_id",$userdata['id']); 
        $this->db->from('floor_plan');
      $query = $this->db->get();
      return $query->result();

       }

会话更改如下。

     <?php
     if (isset($this->session->userdata('logged_in'))) {
       $userdata=$this->session->userdata('logged_in');
     $firstname = $userdata['firstname'];
     $email = $userdata['email'];
    $id = $userdata['id'];
   } else {
    redirect("login/index");
    }
