我正在使用CodeIgniter来开发我的登录系统。通过获取当前用户信息的控制器类的核心扩展，我在整个app控制器中使用$ this-＆gt;用户来显示用户的信息。在我当地的WAMP服务器上，这非常有效。但是，在我的Web服务器上，它始终在您登录后显示来宾的信息。注意var_dump朝向成员获取信息方法的底部。这始终显示正确的帐户信息。但是一旦我从控制器扩展中调用它，它就会显示访客信息。
Controller扩展类：
class MY_Controller extends CI_Controller {
var $user = array();
function __construct(){
parent::__construct();
$this->benchmark->mark('foo');
//$this->output->cache(5);
if(!$this->config->item('global_maintenance')){
$this->member->get_info($this->session->userdata('member_id'));
if($this->member->error == NULL){
$this->user = $this->member->info;
} else {
die($this->member->error);
}
} else {
die('BaseCMD is currently down for routine maintenance. Please try again later!');
}
}
}
会员模型：
<?php
class Member extends CI_Model {
var $info = array();
var $activation_code = '';
var $error = NULL;
function __construct(){
parent::__construct();
$this->error = NULL;

$info = array(
'id' => 0,

好的，所以在从我的控制器扩展，成员模型和我的模板转储变量之后，我意识到我的问题与我的会话或我的类没有任何关系。实际上我的条件语句确定用户是否已登录，而不是我在模板中使用。
<?php
if($this->user['id'] === 0){// This is correct.
echo "You're logged out.";
}
if($this->user['id'] == 0) // This is what I was using and is not correct, apparently.
