我在我的测试站点http://www.weddingsplanner.co.in/test/收到了这么多错误
这是 index.php 的代码，我在页面 db.php 中遇到错误，但我认为如果我能从这里找到一些问题，它会解决
<?php
require_once 'config.php';
function __autoload($class_name)
{
include_once 'library/' . strtolower($class_name) . '.php';
}
$user = new User();
$facebook = new Facebook(array(
'appId' => FB_ID,
'secret' => FB_SECRET,
));
if ($user->isLogged())
{
$registerOrLoginNeeded = false;
}
else
{
$registerOrLoginNeeded = true;
/*
To disable auto login, comment the code used to login automatically.
(Must be used together with documented changes in JavaScript)
Start Here.
*/
$fbUser = $facebook->getUser();
if ($fbUser)
{
try {
$userProfile = $facebook->api('/me');
if ($user->fbLogin($fbUser))
{
$registerOrLoginNeeded = false;
}
else
{
$db = Db::init();
$sth = $db->prepare("SELECT * FROM users WHERE email = ?");
$sth->execute(array($userProfile['email']));
if (false != $sth->fetch())
{
$sth = $db->prepare("UPDATE users SET facebook = ? WHERE email = ?");
if ($sth->execute(array($fbUser, $userProfile['email'])))
{
if ($user->fbLogin($fbUser))
$registerOrLoginNeeded = false;
}
}
}
} catch (FacebookApiException $e) {
$fbUser = null;
}
}
