Data validation on Birthdate and username?

[KatFennec]

The birthday is actually pretty simple.
You just need to drop

PHP Code:

elseif(preg_match('/[01]\d\/[0123]\d\/19\d\d|20[012]\d/', $birthday)){

         $this->seterror("Please enter your birthdate in the format provided.");

         return FALSE;

      } 


into the birthdayvalidate function in the same file.

EDIT:
It looks like I was wrong. You need to partially re-write the birthdayvalidate function like so:

PHP Code:

protected function birthdayvalidate($birthday = ""){
      $lang = Registry::get("lang");
      if(empty($this->value['birthday'])){
         $this->seterror($lang->birthday, TRUE);
         return FALSE;
      }
      if(preg_match_all('/[01]\d\/[0123]\d\/19\d\d|20[012]\d/', $birthday)){

         

         return TRUE;

      }
      else{
         $this->seterror("Please enter your birthdate in the format provided.");
          return FALSE;
      };
  }
