I have a NumericField that represents the amount of items in a video page.
In the CMS i have a NumericField that may only contain a number between 1 and infinity. How can i make a validator on the NumericField so that is doesn't allow negative numbers or a zero?

Any help will be welcome!

note this is code I use in ModelAdmin, so it may require changing to work for a Page...

in the MyPage.php

   function getCMSValidator() {
      return new MyValidator();


class MyValidator extends RequiredFields {
   function php($data) {
      $bRet = parent::php($data);

      $i = (int)$data['ItemsInAVideoPage'];
      if (!ctype_digit($strValue) || $i < 1) {
         $this->validationError('ItemsInAVideoPage','Items In A Video Page must be a non-zero integer',"required");
         $bRet = false;

      return $bRet;
