Error "Requires upload file thrown in" from Facebook Graph API - php

Question

I'm trying to make a script to automatically post a picture to my three fan pages.
Here is the script:
$facebook = new Facebook(array(
'appId' => $fbconfig['appid'],
'secret' => $fbconfig['secret'],
'fileUpload' => true,
));
if($_GET["postType"] == "picture"){$type = "picture";}
else {$type = "link";}
// Download the picture, if $type == picture.
if($type == "picture")
{
$tempFileName = $_SERVER['DOCUMENT_ROOT'].'/TemporaryFiles/';
$tempFileName .= uniqid().'_'.basename($_GET["pictureUrl"]);
// Check if content retrieval is successful :D
if($imgContent = #file_get_contents($_GET["pictureUrl"]))
{
#file_put_contents($tempFileName,$imgContent);
}
}
foreach($pageIDs as $index=>$item)
{
$fbconfig['pageid'] = $item;
$facebook->setFileUploadSupport(true);
if($type == "picture")
{
$args = array(
'access_token' => $pageAccessTokens[$index],
'message' => $_GET["message"],
'source' => '#' . realpath($tempFileName),
);
$post_id = $facebook->api("/" . $albumIDs[$index] . "/photos","post",$args); // Post made :)
}
else if($type == "link")
{
$args = array(
'access_token' => $pageAccessTokens[$index],
'message' => $_GET["message"],
'link' => $_GET["linkUrl"],
'picture' => "",
);
$post_id = $facebook->api("/$pageid/feed","post",$args); // Post made :)
}
}
if($type == "picture")
{
unlink($tempFileName);
}
It's throwing out the following error:
Uncaught OAuthException: (#324) Requires upload file thrown in
I've tried to debug it and have no clue what's wrong with it. If anyone could help, would be grateful.

Answer 1

You need to add photo_upload to your requested scopes to upload images.
array('scope' => 'user_status,publish_stream,user_photos','photo_upload')

Answer 2

put this in your code after the $ facebook-> api ('/ me');
$this->facebook->setFileUploadSupport(true);
