Validation Callbacks!!!

[eluser]reset[/eluser]
Hi Bramme, I add empty to MY_Validation, and it doesn't work.

My Code is:

Code:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class MY_Validation extends CI_Validation{

    function MY_Validation(){
        parent::CI_Validation();
        log_message('debug', 'MY_Validatin Class Initialized');
    }
    
    function greaterthan_sysdate($date){
        $sysdate = date('Ymd');
        $date = substr($date,6).substr($date,3,2).substr($date,0,2);
        if ($date > $sysdate)
            return TRUE;
        return FALSE;    
    }

    function check_date_format($date){
        $ddmmyyyy='(0[1-9]|[12][0-9]|3[01])[- \/.](0[1-9]|1[012])[- \/.](19|20)[0-9]{2}';
           if(preg_match("/$ddmmyyyy$/", $date))
            return TRUE;
        return FALSE;
    }

    function check_date($date){
        if (checkdate((int) substr($date,3,2),(int) substr($date,0,2), (int) substr($date,6)))
                return TRUE;
        return FALSE;
    }
    
    function empty($param){ //line 31
        return empty($param);
    }
    
    function is_array($param){
        return is_array($param);
    }
    

}
?>

And that is the error:
Parse error: parse error, unexpected T_EMPTY, expecting T_STRING in C:\Program Files\EasyPHP 2.0b1\www\uahlabs\system\application\libraries\MY_Validation.php on line 31

Thanks
