Facebook PHP SDK 3.1.1を使用しています このページはヘッダーから値を収集し、後でイメージをアップロードするために使用されます。facebook appリダイレクト後にセッション値が失われる
問題：$_SESSION['file']は、ユーザーがFacebookにログインした後にnullになります。
<?php
require 'facebook.php';
include('connect.php');
$facebook = new Facebook(array('appId' => "XXXXXX",'secret' => "XXXXX","cookie" => true,'fileUpload' => true));
session_start();
$user_id = $facebook->getUser();
if(isset($_REQUEST["src"]))
{
echo "<center><img src='loader.gif'/></center>";
echo "<center><div id='msg'>Exporting Image..</div></center>";
$_SESSION['file'] = $_REQUEST["src"];
$_SESSION['club'] = $_REQUEST["club"];
}
$code = $_REQUEST["code"];
if(empty($code))
{
$_SESSION['state'] = md5(uniqid(rand(), TRUE));
$dialog_url = "http://www.facebook.com/dialog/oauth?client_id=". $app_id . "&redirect_uri=" . urlencode($my_url) . "&state=". $_SESSION['state'];
echo("<script> top.location.href='" . $dialog_url . "'</script>");
exit();
