用Hex的session类取不到值的问题
本帖最后由 liaomars 于 2012-11-20 13:45 编辑我把ci的原session类,换成了Hex大的session类了.但是我输出session的值的时候是空的.这是代码中的一小段代码.$code是有值的
<?php
/*
* 调用验证码
* @author liaoyunyu@gmail.com
* 2012-07-12
*/
class Captcha extends CI_Controller {
function __construct() {
parent::__construct();
//$this->load->library('Authcode');
$this->load->library('captca');
$this->load->library('session');
}
//显示图片
function show(){
$this->captca->doimg();
}
function code(){
echo$code= $this->captca->getCode();
// echo $this->session->userdata('auth_code');
$this->session->set_userdata('auth_code', $code);//设置session
}
}
?>
这上面是session输入的
这下面是取出session值
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Reg extends CI_Controller {
function __construct() {
session_start();
parent::__construct();
$this->load->helper('url'); //加载帮助类的url类
$this->load->library('session'); //加载帮助类的url类
}
public function index() {
$this->load->view('reg_html');
$this->load->view('footer');
}
//用户提交的数据保存
function save() {
//这里需要session的值
if ($_POST['verifycode'] == $this->session->userdata('auth_code')) {
$data = array(
"user" => $this->input->post('AccountName'),
"pass" => md5($this->input->post('AccountPass')),
"email" => $this->input->post('Email'),
