facebook graph api don´t publish to news feed

im trying to update my news feed on facebook. Im using the new graph api. I can connect to graph, but when i try to publish some content to the feed object, nothing happens.

here´s my code:

<?php   
$token = "xxxx";

$fields = "message=test&access_token=$token";

$c = curl_init("http://graph.facebook.com/me/feed");
curl_setopt($c,"CURLOPT_POST", true);
curl_setopt($c,"CURLOPT_POSTFIELDS",$fields);

$r = curl_exec($c);
print_r($r);

this returns:

{"error":{"type":"QueryParseException","message":"An active access token must be used to query information about the 开发者_开发知识库current user."}}1

then I try to pass access_token via GET:

$c = curl_init("http://graph.facebook.com/me/feed?access_token=$token");

this returns:

{"data":[]}1

Am I doing something wrong?

thanks

I found my error! I was putting CURL options as a string rather than constants. oopps...
