php Curl posting to PHPBB

I used to post updates to a forum though a PHP script though my account, Recently it has stopped working, and im not 100% sure why - there are no errors returned by curl and everything seems to be ok apart from the message appearing.

The board im posting to has disable flood limit set for my user and I have permissions to post what ever type of topic is needed

the code to post im using is the following (found online a while ago - minor edits)

$url = "http://url.co.uk/board/";

$post_fields = 'username=user&password=pass&redirect=&login=Log+in';
$lurl = $url."ucp.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$lurl);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch,CURLOPT_COOKIEJAR,"cookie.txt");
$result= curl_exec ($ch);
curl_close ($ch);
$sid1 = explode("sid=",$result);
$sid2 = explode('&',$sid1[1]);
$sid = rtrim(substr($sid2[0], 0, -29),'"');

$purl = url&"posting.php?mode=post&f=20&sid=$sid";
var_dump($purl);
$ch1 = curl_init();
curl_setopt($ch1, CURLOPT_URL,$purl);
curl_setopt($ch1,CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch1, CURLOPT_HEADER, false );
curl_setopt($ch1, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch1,CURLOPT_COOKIEFILE,"cookie.txt");
$result1= curl_exec ($ch1);
curl_close ($ch1);

preg_match('%name="form_token" value="(.*)" />%',$result1,$security123);
preg_match('%name="lastclick" value="(.*)" />%',$result1,$lastclick);
preg_match('%name="creation_time" value="(.*)" />%',$result1,$ctime1);
$lclick = explode('" />',$lastclick[1]);

$title = "title";
$subject = "subject to post";
$post_fields = array(
            'subject'   => $title,
         'message'   => htmlspecialchars_decode($subject),
            'icon'      => 0,
'poll_title' => "Poll Name",
'poll_option_text' => "poll 1rnpoll 2",
'poll_max_options' => 1,
'poll_length' => 0,
'poll_vote_change' => "on",


            'disable_smilies'   => 0,
            'attach_sig'        => 1,
            'notify'           => 0,
         'topic_type'         => 2,
            'topic_time_limit'   => "",
           'creation_time'      => $ctime1[1],
         'lastclick'          => $lclick[0],
          'form_token'   => $security123[1],
              'sid'     =>  $sid,
         'post'   => 'Submit',

         );
print_r($post_fields);
$ch1 = curl_init();
curl_setopt($ch1, CURLOPT_URL,$purl);
curl_setopt($ch1, CURLOPT_POST, 1);
curl_setopt($ch1, CURLOPT_POSTFIELDS, $post_fields);
curl_setopt($ch1,CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch1, CURLOPT_HEADER, false );
curl_setopt($ch1, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch1,CURLOPT_COOKIEFILE,"cookie.txt");
$result2= curl_exec ($ch1);
if(curl_errno($ch1))
{
    echo 'Curl error: ' . curl_error($ch1);
}
curl_close ($ch1);
echo $result2;

From this $result2 has the output threads from the forum, But the message submitted hasnt been posted.

I am logged in ok in $result2 with no error messages visible.

Any suggestions ? ive checked sid, form_token, lclick and creation_time and they all seem to be the same and correct.

Solved it

posting.php line 49

if ($cancel || ($current_time - $lastclick < 2 && $submit))

Although flood is disabled for my user there is still a hard coded delay of 2 seconds that i have to stick to.
