Question

I am working on a site and i need to post page links from that site to a special user wall or page if something is published on it which means i only need one user to post that question.

the problem which i am facing is access token since i am not trying to show facebook login page in front of website traffic. its not like sharing on user wall we are basically trying to post status on a page automatically so any help for this problem will be appreciated.

i am using the following code which seems to work fine as long as the access token for the page is valid but i need to make something permanent so that i can add all the info in the php code hardcoded and it work for some weeks at-least without changing the api key or token

$appid = 'code';
$appsecret = 'code';
$wall= $pageId = 'code';

$token='page token';

$facebook = new Facebook(array('appId'  => $appid, 'secret' => $appsecret, 'cookie' => true));

$params=array( 'message' => $msg,'name' => $title, 'caption' => $title, 'link' =>$uri,'description' => $desc, 'picture' => $pic, 'access_token' => $token,'actions' => json_encode(array('name' => $action_name,'link' => $action_link)) );

$result = $facebook->api($wall.'/feed/','post',$params);

if i make token from the graph api debug page then it works fine but after some time i got the message “OAuthException: An active access token must be used to query information about the current user.”

i am really desperate to find something solid for it.

thank you

You can write a backend script (maybe a cron job using the FB PHP-SDK) that runs as the special user and makes the desired FB api calls. For this, you will want to use a long-lived access token, which needs to be renewed every 60 days. You might also try your FB api calls using an App Access Token, which do not expire but also do not support all FB publishing and other operations.
