linkback check

[Chris2k]

it works as i planned, not bad for a noob. 1 prob, its not blacklisting heres m y code:

function linkback($link, $ururl)  
{  
    $ch = curl_init($link);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
    curl_setopt($ch, CURLOPT_HEADER, 0);  
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  
    curl_setopt($ch, CURLOPT_USERAGENT, 'Opera/9.80 (Windows NT 5.1; U; en) Presto/2.7.62 Version/11.01');  
    $page = curl_exec($ch);  
    curl_close($ch); 
    if (stripos($page,$ururl)===false) 
      return false; 
    else 
      return true;
}

$ururl = "http://warezrelease.org";

$reason = "Add our linkback, then email us.";

$date = date("d-m-Y");

  if(linkback($surl,$ururl)==true)
  {
mysql_query("INSERT INTO wcddl_queue (sid,title,type,url) VALUES ('".mysql_real_escape_string($sid)."','".mysql_real_escape_string($titles[$i])."','".mysql_real_escape_string($types[$i])."','".mysql_real_escape_string($urls[$i])."')");
  }
  else
  {
  die('We cant find our link on your site, please add it.');
   
  $b = mysql_query("INSERT INTO wcddl_blacklist VALUES ('".mysql_real_escape_string($surl)."','".mysql_real_escape_string($reason)."','".mysql_real_escape_string($date)."','".mysql_real_escape_string($email)."')");
  } 

can some1 take a look.
