因此,我有一个登录脚本,它调用一个自定义用户类,用户登录并设置会话。在login.php页面的redict上做一个var转储,确认用户已经成功登录,并显示友好的欢迎消息。PHP会话在登录时存在,但不在另一页上登录
设置会话的代码是:
private function setIsLoggedIn($credentials) {
if (!isset($_SESSION)) {
session_start();
}
$_SESSION['verified'] = $credentials;
session_write_close();
}
这是对的login.php页面做工精细,该函数的自变量是:
// assign user info from db to the session
$this->setIsLoggedIn(array('UserId' => $user->userid,
'UserName' => $user->username,
'RoleId' => $user->roleid));
这是login.php中表格回发
// if the form was submitted
if (isset($_POST['submit'])) {
// Set local variables from $_POST array elements (userlogin and userpassword) or empty strings
$userLogin = (isset($_POST['userlogin'])) ? trim($_POST['userlogin']) : '';
$userPassword = (isset($_POST['userpassword'])) ? trim($_POST['userpassword']) : '';
//assign values to array and get user object
$authArray = array('UserName' => $userLogin, 'Password' => $userPassword);
$user = new Users($authArray);
if ($user->getUserId() > 0) { //If credentials check out
// redirect the user to SESSION value set from common class
if (isset($_SESSION['prev_page']))
{
header('location:' . $_SESSION['prev_page']);
exit;
}
else
{
// Otherwise, assign error message to $msg
$msg = '<p><strong>Thank your for logging in.<br />You may now visit tools that are in development.</strong></p>';
}
}
else
{
// Otherwise, assign error message to $msg
$msg = '<p><strong>Sorry, that username and password are not recognized.<br />Please try again.</strong></p>';
}
}
现在我到另一个页面并执行$ var_dump($ _ SESSION);我总是别的东西,因为在页面上我设置这样的:
$_SESSION['prev_page'] = "http://".$_SERVER[SERVER_NAME]."/id/AphID/";
该文件的第一行是:
<?php
session_start();
var_dump($_SESSION);
这里是我的PHP会话设置:
Session Support enabled
Registered save handlers files user
Registered serializer handlers php php_binary wddx
Directive Local Value Master Value
session.auto_start Off Off
session.bug_compat_42 On On
session.bug_compat_warn On On
session.cache_expire 180 180
session.cache_limiter nocache nocache
session.cookie_domain no value no value
session.cookie_httponly Off Off
session.cookie_lifetime 0 0
session.cookie_path//
session.cookie_secure Off Off
session.entropy_file /dev/urandom /dev/urandom
session.entropy_length 16 16
session.gc_divisor 1000 1000
session.gc_maxlifetime 1440 1440
session.gc_probability 1 1
session.hash_bits_per_character 5 5
session.hash_function 0 0
session.name PHPSESSID PHPSESSID
session.referer_check no value no value
session.save_handler user files
session.save_path /tmp /tmp
session.serialize_handler php php
session.use_cookies On On
session.use_only_cookies Off Off
session.use_trans_sid 1 1
所以,基本上我的会话只在登录页面上存在,并且没有其他地方,并且当我调用Session_start();我总是得到一个不同的会议。有任何想法吗?
会话哪里设置你$ _SESSION [ 'prev_page']?如果它在session_write_close调用后设置,则不起作用。 – 2012-03-20 21:46:45
