function send_mail($mailer,$to_name,$to_email,$from_name,$from_email,$subject,$msg,$email=true)

                      {

                          if ($email)

                          {

                            if ($mailer)

                            {

                              $MAILER = new PHPMailer();

 

                              $MAILER->IsSMTP();

                              $MAILER->Host      = "localhost";

                              $MAILER->SMTPAuth  = false;

                              $MAILER->IsHTML(false);

                              $MAILER->From      = $from_email;

                              $MAILER->FromName  = $this->char_back($this->strip_slashes($from_name));

                              $MAILER->AddAddress($to_email, $to_name);

                              $MAILER->Subject    = $subject;

                              $MAILER->Body      = $this->char_back($this->strip_slashes($msg));

                              $MAILER->Send();

                            }
