页面加载之间失去了与本地主机上WAMPserver 2.0 PHP会话数据 [英] PHP SESSION data lost between page loads with WAMPserver 2.0 on localhost

问题描述

我有一个PHP的认证系统上使用$ _SESSION变量我的网站。

一个表单提交的用户名和密码的文件的login.php。它是这样处理的：

 ＆LT;？PHP的包括../includes/sessionstart.inc.php'; ？＆GT;
＆LT;？PHP的ob_start（）; ？＆GT;如果（$ _ POST）{
    $ Q =的mysql_query（SELECT ID，公司从用户其中username ='.mysql_real_escape_string（$ _ POST ['用户名']）。'和密码='.md5（$ _ POST ['密码']）。' ）;
    如果（mysql_num_rows（$ Q）＆GT; = 1）{
        $ F = mysql_fetch_Array（$ Q）;
        $ _SESSION ['公司'] = $ F ['公司'];
        $ _SESSION ['身份证'] = $ F ['身份证'];
        $ _SESSION ['logedin'] =真;
        session_write_close（）;        ob_clean（）;
        标题（地点：的index.php）;}
 

之后，index.php文件被加载，并检查logedin是否是真实的。

 ＆LT;？PHP的包括../includes/sessionstart.inc.php'; ？＆GT;
？＆LT;如果PHP（！使用isset（$ _ SESSION ['logedin']））标题（位置：login.php中'）; ？＆GT;
 

在我的生产服务器，它继续进行，但在我的Wampserver，它将恢复为login.php中。我注意到，Wampserver在页面加载速度很慢，这可能需要用它做什么。这就是为什么我包括session_write_close，使切换页面之前，请确保会话数据被保存，但它并不能帮助。

session_start.inc.php的内容是简单的：

 ＆LT; PHP
    在session_start（）;
？＆GT;
 

我以前有更多的code在那里，但目前它只是这个。之前，我开始使用一个包含文件的问题也存在。

没有任何人有一个想法，我做错了什么？为什么不Wampserver我的会话数据传输到下一个PHP文件？

解决方案

在我终于修正了这个错误很长的时间。

在我的本地WAMP，会话数据不保存页面加载之间，因为会话数据存储在cookie中，有对本地主机设置没有cookie域。

解决方案：

  

session.cookie_domain'应该被设置为空字符串所有本地域名，不仅关于'本地主机'（但不应该是空的本地IP地址）：

 ＆LT; PHP
的ini_set（'。'！'session.cookie_domain'，（strpos（$ _ SERVER ['HTTP_HOST']）==假）$ _ SERVER ['HTTP_HOST']：''）;
？＆GT;
 

由于马尔钦Wiazowski 谁张贴在这里。

I have a PHP authentication system on my website using the $_SESSION variable.

A form submits a username and password to the file "login.php". It is handled like this:

<?php include '../includes/sessionstart.inc.php'; ?>
<?php ob_start(); ?>

if($_POST){
    $q = mysql_query("SELECT id, company FROM users WHERE username = '".mysql_real_escape_string($_POST['username'])."' AND password = '".md5($_POST['password'])."'");
    if(mysql_num_rows($q) >= 1){
        $f = mysql_fetch_Array($q);
        $_SESSION['company'] = $f['company'];
        $_SESSION['id'] = $f['id'];
        $_SESSION['logedin'] = true;
        session_write_close();

        ob_clean();
        header("Location: index.php");

}

Afterwards, index.php is loaded and checks whether 'logedin' is true.

<?php include '../includes/sessionstart.inc.php'; ?>
<?php if(!isset($_SESSION['logedin'])) header('Location: login.php'); ?>

On my production server, it continues, but on my Wampserver, it reverts back to login.php. I notice that Wampserver is very slow in page loading, this might have to do something with it. That's why I included the session_write_close, to make sure session data is saved before the pages are switched, but it doesn't help.

The contents of session_start.inc.php are simply:

<?php
    session_start();
?>

I used to have more code in there, but at the moment it's just this. The problem also existed before I started using an include file.

Does anybody have an idea what I'm doing wrong? Why doesn't Wampserver transmit my SESSION data to the next PHP file?

解决方案

After a long time I have fixed this bug finally.

On my localhost WAMP, the session data is not saved between page loads, because the session data is stored in a cookie, and there is no cookie domain to be set for localhost.

The solution:

'session.cookie_domain' should be set to empty string for all local domain names, not only for 'localhost' (but should not be empty for local IP addresses):

<?php
ini_set('session.cookie_domain', (strpos($_SERVER['HTTP_HOST'],'.') !== false) ? $_SERVER['HTTP_HOST'] : '');
?>
