php - FACEBOOK auto posting to facebook site (Curl)

I am trying to implement auto posting through cron to a facebook site that I created. The hard part about this is: no account is logged in during the process.

I checked a lot of sites for my problem and somehow it still doesn't work... Does anybody see any problem in my code QQ HELP

$username = "xx";
$password = "xx";

// access to facebook home page (to get the cookies)
$curl = curl_init ();
curl_setopt ( $curl, CURLOPT_URL, "http://www.facebook.com" );
curl_setopt ( $curl, CURLOPT_FOLLOWLOCATION, 1 );
curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $curl, CURLOPT_ENCODING, "" );
curl_setopt ( $curl, CURLOPT_COOKIEJAR, getcwd () . '/cookies_facebook.cookie' );
curl_setopt ( $curl, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"] );
$curlData = curl_exec ( $curl );


// do get some parameters for login to facebook
$charsetTest = substr ( $curlData, strpos ( $curlData, "name=\"charset_test\"" ) );
$charsetTest = substr ( $charsetTest, strpos ( $charsetTest, "value=" ) + 7 );
$charsetTest = substr ( $charsetTest, 0, strpos ( $charsetTest, "\"" ) );

$locale = substr ( $curlData, strpos ( $curlData, "name=\"locale\"" ) );
$locale = substr ( $locale, strpos ( $locale, "value=" ) + 7 );
$locale = substr ( $locale, 0, strpos ( $locale, "\"" ) );

$lsd = substr ( $curlData, strpos ( $curlData, "name=\"locale\"" ) );
$lsd = substr ( $lsd, strpos ( $lsd, "value=" ) + 7 );
$lsd = substr ( $lsd, 0, strpos ( $lsd, "\"" ) );

// do login to facebook
curl_setopt ( $curl, CURLOPT_URL, "https://login.facebook.com/login.php?login_attempt=1" );
curl_setopt ( $curl, CURLOPT_POST, 1 );
curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt ( $curl, CURLOPT_POSTFIELDS, 
    "charset_test=" . $charsetTest . 
    "&locale=" . $locale . 
    "&non_com_login=&email=" . $username . 
    "&pass=" . $password . 
    "&charset_test=" . $charsetTest . 
    "&lsd=" . $lsd );
curl_setopt ( $curl, CURLOPT_COOKIEFILE, getcwd () . '/cookies_facebook.cookie' );
$curlData = curl_exec ( $curl );//this actually is the code of my facebook profile page so it works


//Page access_token
$access_token = "xx";   
$params=array(
      'access_token'=>$access_token, 
      'message'=> "Testing newwjjj7wwwg", 
      'name'=>'TEST6678888');

//Postng to facebook page
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($curl, CURLOPT_URL, "https://graph.facebook.com/".variable_get('webconnect_facebook_pageId')."/feed");
$result = curl_exec($curl);

curl_close ($curl);
Copy code

When I try to make a post:{ "error": { "message": "Error validating access token: This may be because the user logged out or may be due to a system error.", "type": "OAuthException", "code": 190, "error_subcode": 467 } }

When I try to use the user access_token:{ "error": { "message": "(#200) The user hasn't authorized the application to perform this action", "type": "OAuthException", "code": 200 } }

The thing is I did authorize it... Any ideas ??
