Question

I have created an app, and now i want to post a message on one of my friends wall with use of the new Graph API. Is this do-able?

I am already using oAuth and the Graph-api to get a list of all my friends.
The API at http://developers.facebook.com/docs/api tells me to cURL https://graph.facebook.com/%5Buserid%5D/feed to read the feed, but it also tells me howto post a message:

curl -F 'access_token=[...]' -F 'message=Hello, Arjun. I like this new API.' https://graph.facebook.com/arjun/feed

Ofcourse this doesn’t work! And I can’t find out why..

Here are my PHP-code:

require_once 'facebook.php'; // PHP-SDK downloaded from http://github.com/facebook/php-sdk
$facebook = new Facebook(array(appId=>123, secret=>'secret'));
$result = $facebook->api(
        '/me/feed/',
        array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..')
);

This code does not throws any error, and I know my access_token are correct (otherwise i could’t run $facebook->api(‘/me?access_token=’.$this->access_token); to get my userobject.

Have anyone out there sucsessfully posted a message using Graph-api? Then i need your help! 🙂

Okay, I finally solved this. Thanx to phpfour for your help 🙂

First: My connection-url looks like this (with “publish_stream”):

$connectUrl = $this->getUrl(
  'www',
  'login.php',
  array_merge(array(
    'api_key'         => $this->getAppId(),
    'cancel_url'      => $this->getCurrentUrl(),
    'req_perms'       => 'publish_stream',
    'display'         => 'page',
    'fbconnect'       => 1,
    'next'            => $this->getCurrentUrl(),
    'return_session'  => 1,
    'session_version' => 3,
    'v'               => '1.0',
  ), $params)
);

Second; I tried to post to facebook via

$result = $facebook->api(
    '/me/feed/',
    array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..')
);

But the correct way to do this is include one more parameter (‘post’):

$result = $facebook->api(
    '/me/feed/',
    'post',
    array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..')
);
