thanks!

check select query.... "url_domein" or "url_domain"?

what trying in insert method?

i couldnt see prepared statements have called execute method?

 $query->execute(         array(             ':created_time'     =>  date('d-m-o'),             ':swf_theme'            =>  $_post['image'] . ".swf",             ':url_text'             =>  explode('/', $_post['url'])[1],             'url_domain'            =>  explode('/', explode(".", $_post['url'])[1])[0],             ':creator_ip'           =>  $_server['remote_addr'],             ':creator_name' =>  $_post['creator_name'],             ':creator_text'     =>  $_post['creator_text'],             ':creator_email'    =>  $_post['creator_email']         )     );

try change query this... use prepare

$query = $pdo->prepare('insert trolls (created_time, swf_theme, url_text, url_domain, creator_ip, creator_name, creator_text, creator_email)          values (:created_time, :swf_theme, :url_text, :url_domain, :creator_ip, :creator_name, :creator_text, :creator_email)');

use try catch block query know error

try {        // query here        } catch (pdoexception $pe) {           die("error:" . $pe->getmessage());       }
