I need it now and have make this:

In template.inc at the end a new function:

 
/******************************************************************************
  * This function strip comments from templates.
  *
  * Returns: 
  *
  * @param     $str
  * @access    public
  * @return    string
  */
  function delete_comment($str) {
    if ($this->debug & 1) {
      print("<b>Varname:</b> $str<br>\n");
    }
    
    $left_delimiter = '{*';
    $right_delimiter = '*}';

    // Quote regular expression characters
    $ldq = preg_quote($left_delimiter, '!');
    $rdq = preg_quote($right_delimiter, '!');

    $str = preg_replace("!$ldq(.*?)$rdq!se", "", $str);
    
    return $str;
  }


Its not the best, but it works.

And i have write it in the finish function:


  function finish($str) {
    switch ($this->unknowns) {
      case "keep":
        $str = $this->delete_comment($str);
      break;

      case "remove":
        $str = preg_replace('/{[^ \t\r\n}]+}/', "", $str);
        $str = $this->delete_comment($str);
      break;

      case "comment":
        $str = preg_replace('/{([^ \t\r\n}]+)}/', "<!-- Template variable \\1 
undefined -->", $str);
        $str = $this->delete_comment($str);
      break;
    }

    return $str;
  }



Better ideas are welcome (-;
