[php + cURL] odpowiadanie w temacie

Witam wszystkich. Chciałem napisać skrypt, który odpowie mi automatycznie np. w tym temacie, tak więc w curl musi się pierw zalogować, a pozniej napisac odpowiedź. Jednak mam trochę problem ;/

probowalem napisać, jednak logowanie nawet mi się nie udaje

<?
curl_login('http://www.test.org/login.php?','username=ss&password=ss&autologin=on&login=Log+in','','off');


function curl_login($url,$data,$proxy,$proxystatus){
    $fp = fopen("cookie.txt", "w");
    fclose($fp);
    $login = curl_init();
    curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt");
    curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt");
    curl_setopt($login, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
    curl_setopt($login, CURLOPT_TIMEOUT, 40);
    curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE);
    if ($proxystatus == 'on') {
        curl_setopt($login, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($login, CURLOPT_HTTPPROXYTUNNEL, TRUE);
        curl_setopt($login, CURLOPT_PROXY, $proxy);
    }
    curl_setopt($login, CURLOPT_URL, $url);
    curl_setopt($login, CURLOPT_HEADER, TRUE);
    curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($login, CURLOPT_POST, TRUE);
    curl_setopt($login, CURLOPT_POSTFIELDS, $data);
    ob_start();      // prevent any output
    return curl_exec ($login); // execute the curl command
    ob_end_clean();  // stop preventing output
$postFields['url']="http://test/posting.php?mode=reply&t=910943?";
$postFields['message']="tak";
$postFields['t']=910943;
$postFields['post']="Submit";
$ch = curl_init('http://test/posting.php?mode=reply&t=910943?message=tak&post=Submit');
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_exec($ch);
    curl_close ($login);
    unset($login);    
}      
?>

na pewno dobrze się loguje, natomiast nie odpisuje w danym temacie tak więc za to odpowiada kod:

$postFields['url']="http://test/posting.php?mode=reply&t=910943?";
$postFields['message']="tak";
$postFields['t']=910943;
$postFields['post']="Submit";
$ch = curl_init('http://test/posting.php?mode=reply&t=910943?message=tak&post=Submit');
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_exec($ch);

Niestety nie wiem co może być wyżej źle.

Proszę o pomoc

Daj nazwe skryptu i URL prawdziwy. Może są jakieś ukryte pola w formularzu. Poza tym "Mozilla/4.0" to mi nie wygląda na zbyt akceptowalny User-Agent.
