filter wpcf7_validate_text doesn't seem to work with qtranslate?

Hello,

So i added a custom filter wpcf7_validate_text validation but it doesn’t seem to work with qtranslate and a form in another language.

function cf7_custom_form_validation($result,$tag) {
    $type = $tag['type'];
    $name = $tag['name'];
    $code= $_POST['gotcode'];
    $invcode= $_POST['invcode'];
    $gatewaycode= $_POST['gateway_code'];
  if(($name == 'gotcode') && ($hebcode=='1')){
      if($invcode == ''){
        $result['valid'] = false;
        $result['reason']['gotcode'] = 'No code';
      }
      if($invcode == 'No valid code'){
         $result['valid'] = false;
        $result['reason']['gotcode'] = 'No valid code';
      }
  }
  if(($name == 'gotcode') && ($hebcode=='0')){
      if($gatewaycode=='free'){
        $result['valid'] = false;
        $result['reason']['gotcode'] = 'Select Payment method';
      }
  }
 return $result;
}
add_filter('wpcf7_validate_radio','cf7_custom_form_validation', 10, 2);

How can i fix this?

btw: i have one select menu as html code not with WPCF7 shortcode, should i add a class?
