Question

I am developing my first facebook app, which includes creating a new album and posting photos to the user wall.

By learning through facebook documentation and few tutorial and came up this code, but I am getting following error with it.

Fatal error: Call to a member function setFileUploadSupport() on a non-object …

        $facebook -> setFileUploadSupport(true);
        $album_details = array('message' => 'Album desc', 'name' => 'Album name');
        $create_album = $facebook -> api('/me/albums', 'post', $album_details);
        $album_uid = $create_album['id'];

        $photo_details = array('message' => 'Photo message');
        $file = 'app.jpg';
        $photo_details['image'] = '@' . realpath($file);

        $upload_photo = $facebook -> api('/' . $album_uid . '/photos', 'post', $photo_details);

Kindly help me with this. thankyou

You will need instantiate the class with file upload support and request the correct permissions.

$facebook = new Facebook(array(
    'appId'  => 'YOUR_APP_ID',
    'secret' => 'YOUR_APP_SECRET',
    'fileUpload' => true // enable file upload support
));

// get a login url with the correct perms
$facebook->getLoginUrl(array(
  'scope' => 'photo_upload,first_name,email,publish_stream,read_stream'
));

photo_upload is the key permission here, allowing you to upload photos.
