Authorizing a Facebook Fan Page for Status Updates

Question

I'm able to update the status on my PROFILE wall using this code:

require_once 'facebook-platform/php/facebook.php';
$facebook = new Facebook('APP API KEY','APP SECRET KEY');
$user_id = 'MY USER ID';
$facebook->api_client->users_setStatus('This is a new status');

...after authorizing using this address: http://facebook.com/authorize.php?api_key=MYAPPAPIKEY&v=1.0&ext_perm=publish_stream

This code, however, does not work to update the status on my Facebook PAGE Wall. Are there additional parameters that I can add to the authorize.php url to specify authorizing the PAGE and not just my profile?

Or, are there better ways to post updates to Fan Page Walls?

Thanks!

Answer 1

I solved the problem by consulting the Facebook desktop application documentation (even though this is a web application).

I first had to authorize offline access with this url (replacing 'MYAPIKEY'): http://www.facebook.com/login.php?api_key=MYAPIKEY&connect_display=popup&v=1.0&next=http://www.facebook.com/connect/login_success.html&cancel_url=http://www.facebook.com/connect/login_failure.html&fbconnect=true&return_session=true&session_key_only=true&req_perms=read_stream,publish_stream,offline_access

Then, I needed to grant 'publish_stream' permissions to the PAGE with this url (replacing 'MYAPIKEY' and 'THEPAGEID'): http://www.facebook.com/connect/prompt_permissions.php?api_key=MYAPIKEY&v=1.0&next=http://www.facebook.com/connect/login_success.html?xxRESULTTOKENxx&display=popup&ext_perm=publish_stream&enable_profile_selector=1&profile_selector_ids=THEPAGEID

I could then use the following code to publish to the Fan Page wall:

require_once 'facebook-platform/php/facebook.php';
$facebook = new Facebook(MYAPIKEY, MYAPISECRET);
try{
    $facebook->api_client->stream_publish('INSERT_STATUS_HERE',null,null,null,'THEPAGEID');
}catch(Exception $o ){
    print_r($o);
}
