Some other php code

My Code .
</html>
i got 2 Problems .
It is redirect to Facebook Home Page . See Demo : https://apps.facebook.com/246435698815637/
this is "$image = $images[ rand(0,(count($images)-1)) ];" is not working some time . it is didn't get image for imagecreatefromjpeg
Try like this and please avoid the blank statements.
if(!($me))
{
echo '<script> top.location.href="'.$facebook->getLoginUrl(array(
'req_perms' => $permsneeded,
'next' =>'https://apps.facebook.com/246435698815637/',
)). '";
</script>';
exit();
}
and second one is correct,it should work,but i don't get your point about imagecreatefromjpeg as you don't give any information about it.Paste your code where you have use that function.

I need some help, I am trying to implement facebook login in my website and right from the
get-go I am getting an error.
Error Class facebook\HttpClients\HttpClient Factory' not found
What does that even mean?
my code so far is pretty simple
in page one which for the example I called config.php, I write this little bit of code.
Page 1) config.php .
page 2) login.php
What am I doing wrong.. I am doing this on my own so I am pretty confused. Any help would be very much apprecitated.
I am not an expert. First time I am messing with facebook API so I apologize in advance.

I am trying to post on behalf of user. I have used tutorial given on this page: http://25labs.com/updated-post-to-multiple-facebook-pages-or-groups-efficiently-v2-0/ .
I could successfully perform authentication but could not post on behalf.
Here is the source code : https://github.com/karimkhanp/fbPostOnBehalf
Testing can be done here: http://ec2-54-186-110-98.us-west-2.compute.amazonaws.com/fb/
Does any one experienced this?
I'm not familiar with the batch process that the tutorial is using but below is a code sample that posts to a Facebook group

i am using FB SDK v.3.2.3 , and i'm trying to retrieve the events that my friends are going to. So far, my code can retrieve the list of friends who are using my app. The documentation on FB tells the event can be pulled out by using "me/events", but since i want my friend's event to be pulled, i used "me/friends/event" or "me/friends?fields=event", but it still does not work. Someone has an idea about it? Below is my code --
<pre>
require_once('facebook.php');
$config = array(
'appId' => 'xxx',
'secret' => 'xxx'
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
if($user_id) {
try {
$user_profile = $facebook->api('/me','GET');
echo "<pre>";
print_r($user_profile);
echo "</pre>";
$dost = $facebook->api('/me/friends','GET');
foreach ($dost as $friend) {
echo "<pre>";
print_r($friend);
echo "</pre>";
}
echo '<br><a href=' . $facebook->destroySession() . '>Logout</a>';
} catch(FacebookApiException $e) { }
} else {
$params = array(
'scope' => 'public_profile, user_friends, email',
'redirect_url' => 'http://xxxxx.com',
'auto_logout_link' => 'true',
'show_faces' => 'true'
);
$login_url = $facebook->getLoginUrl($params);
echo 'Please login.';
}
Try it:
//...
$dost = $facebook->api('/me/friends','GET');
foreach ($dost["data"] as $value) {
$friend_id = $value['id'];
$events = $facebook->api('/'.$friend_id.'/events');
print_r($events);
}
//...
Facebook changed the privacy policy for friends - your friends also need to give permission to your app

Need help! :O
I solved, the problem is that I should use the access_token of the page, that is not static, well I have to look in my /profile/accounts
$params = array('access_token' => $access_token);
$accounts = $facebook->api('/giacomo.torricelli/accounts', 'GET', $params);
foreach($accounts['data'] as $account) {
if( $account['id'] == $fanpage || $account['name'] == $fanpage ){
$fanpage_token = $account['access_token'];
}
}
Thanks
im try to make a fan gate content for my facebook fan page by singed_request. The code work perfectly but i don't want redirect in iframe, i need redirect after the user click LIKE to another page. How i can remove iframe and insert a redirect?
this is my code:
<?php
require_once('facebook.php');
$app_id = "id";
$app_secret = "secret";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
$signed_request = $facebook->getSignedRequest();
function parsePageSignedRequest() { if (isset($_REQUEST['signed_request'])) { $encoded_sig = null; $payload = null; list($encoded_sig, $payload) = explode('.', $_REQUEST['signed_request'], 2); $sig = base64_decode(strtr($encoded_sig, '-_', '+/')); $data = json_decode(base64_decode(strtr($payload, '-_', '+/'), true)); return $data; } >return false; } if($signed_request = parsePageSignedRequest()) { if($signed_request->page->liked) { echo "<iframe allowtransparency=\"true\" frameborder=\"0\" SCROLLING=\"YES\" style=\"width: 800px; height: 1000px;\" src=\"http://onlyimagination.com/dm3theme2\" id=\"any_name\" name=\"anyname\"><iframe>";
} else { echo "<img src=\"http://www.onlyimagination.com/facebook/crazyvideo/img.jpg\" width=\"582\" height=\"487\">"; } }
?>
This will only work if don't have any output before your code
if ($signed_request = parsePageSignedRequest()) {
if ($signed_request->page->liked) {
header('Location: http://onlyimagination.com/dm3theme2');
} else {
echo "<img src=\"http://www.onlyimagination.com/facebook/crazyvideo/img.jpg\" width=\"582\" height=\"487\">";
}
}
