Can't pass a session variable logging in with OpenID? - php

Question

I tried running this code which creates a SESSION variable for the Google email but for some reason the $_SESSION['email'] does not want to store the data. I run the code and the only output I get after signing in with google is
hello world 1
hello world 2
<?php
session_start();
require 'openid.php';
$openid = new LightOpenID('http://www.splunk.com');
if (!$openid->mode)
{
$openid->identity = 'https://www.google.com/accounts/o8/id';
$openid->required = array('contact/email');
header('Location: ' . $openid->authUrl());
}
else
{
if ($openid->validate())
{
//echo "Hello World!";
$attributes = $openid->getAttributes();
$google_email = $attributes['contact/email'];
$_SESSION['email'] = $google_email;
echo $google_email."<br />";
echo "<pre>" . print_r($_GET, true) . "</pre>";
echo $_GET['contact_email'];
header("Location: " . google_login.php);
}
else
{
echo '<p>hello world 1</p>';
echo "<p>". $_SESSION['email']. "</p>";
echo '<p>hello world 2</p>';
}
}
?>
I modified the above example with the google example from the LightOpenID site but now it doesn't validate for some reason.
<?php
# Logging in with Google accounts requires setting special identity, so this example shows how to do it.
require 'openid.php';
try
{
# Change 'localhost' to your domain name.
$openid = new LightOpenID('http://www.splunk.com');
if(!$openid->mode)
{
if(isset($_GET['login']))
{
$openid->identity = 'https://www.google.com/accounts/o8/id';
$openid->required = array('contact/email');
header('Location: ' . $openid->authUrl());
}
?>
<form action="?login" method="post">
<button>Login with Google</button>
</form>
<?php
}
else if($openid->mode == 'cancel')
{
echo 'User has canceled authentication!';
}
else
{
$attributes = $openid->getAttributes();
$google_email = $attributes['contact/email'];
echo $google_email;
echo 'User ' . ($openid->validate() ? $openid->identity . ' has ' : 'has not ') . 'logged in.';
}
} catch(ErrorException $e) {
echo $e->getMessage();
}
