如何在 Codeignitor 中获取会话 ID

Question

How to retrieve session-id in codeignitor? since I was new to the framework the documentation is too unfamiliar to me

Answer 1

first of all you should put the query or CI ACTIVE RECORD in model, NOT IN Controller..

try this

$user->YourIDTableColumn

CI DB ACTIVE RECORD

Answer 2

多年后我得到了答案，因为当时我在 codeignitor 方面的经验较少，我感到困惑我知道这是一个非常简单的问题，但那是我开始使用 codeignitor 的那一天，所以我自己写了答案

$session_id = $this->session->userdata('id');

Answer 3

If you want id of session than you can use session_id . One more thing please use to load session in application/config/autoload.php

$autoload['libraries'] = array('session');

Than you can use it in controller or model or view.

$this->load->library('session');

echo $this->session->session_id; 

Or if you want some user info like email, id etc so you can use.

echo $this->session->userdata("email");

Answer 4

首先，您需要在用户登录时将用户 ID 获取到会话数据数组中。让我们认为您的会话数据数组是user_data() 。

$userid = $this->session->user_data('user_id');
