I'm trying to upload www hosted (e.g. http://www.google.se/intl/en_com/images/srpr/logo1w.png) files to a facebook album.
Creating an album works just fine, but I don't seem to uploading any photos. I'm using the facebook php-sdk ( http://github.com/facebook/php-sdk/ ) and the examples I already tried are:
Upload Photo To Album with Facebook's Graph API
How can I upload photos to album using Facebook Graph API
I'm guessing CURL uploads perhaps only can manage locally stored files and not web hosted ones.
Here's my code:
/*
Try 1:
$data = array();
$data['message'] = $attachment->post_title;
$data['file'] = $attachment->guid;
try {
$photo = $facebook->api('/' . $album['id'] . '/photos?access_token=' . $session['access_token'], 'post', $data);
} catch (FacebookApiException $e) {
error_log($e);
}
*/
// Try 2:
//upload photo
$file = $attachment->guid;
$args = array(
'message' => 'Photo from application',
);
$args[basename($file)] = '@' . realpath(file_get_contents($file));
$ch = curl_init();
$url = 'https://graph.facebook.com/' . $album['id'] . '/photos?access_token=' . $session['access_token'];
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
$data = curl_exec($ch);
//returns the photo id
print_r(json_decode($data,true));
...where attachment->guid contains the photo url.
I'm pretty much stuck right now...
