FB Developer: Uncaught OAuthException: (#120) Invalid album id - php

Question

i'm trying to post photos on a fanpage and I get this error:
Fatal error: Uncaught OAuthException: (#120) Invalid album id thrown in /home/eyikmdnu/public_html/jack/facebook-sdk/base_facebook.php on line 1264
This is the code of the page (obv the token, the secret etc are not the "original"
require_once("../facebook-sdk/facebook.php");
define("APP_ID", "*****");
define("APP_SECRET", "********");
$fanpage_token = "*******";
$user_access_token = "********";
$config = array(
'appId' => APP_ID,
'secret' => APP_SECRET,
'fileUpload' => true // optional
);
$facebook = new Facebook($config);
//pagina = 358226040977616
//album id = 402459486554271
//$access_token = $_POST['access_token'];
//echo $access_token;
$facebook->setAccessToken($fanpage_token);
echo "Access Token Settato <br>\n";
$facebook->setFileUploadSupport(true);
echo "setFileUploadSupport(true) settato <br>\n";
$img_url = "images/jack.png";
//$img_url = $_POST['url'];
echo "$img_url = $img_url <br>\n";
$page_id = "358226040977616";
$album_id = "402459486554271";
echo "Page id: $page_id <br>\n";
echo "Album id: $album_id <br>\n";
$real_img_url = realpath($img_url);
echo "Real img url: $real_img_url <br>\n";
$args = array(
'message' => 'message to write in legend',
'image' => "#" . $img_url,
'aid' => $album_id,
'no_story' => 1,
'access_token' => $fanpage_token
);
echo "<br>\n";
print_r($args);
echo "<br>\n";
$photo = $facebook->api("/".$album_id."/photos", 'post', $args);
print_r($photo);
Need help! :O

Answer 1

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
