You'll need Javascript.

You can't do this, as mentioned previously, without javascript of some description. You can use javascript validation or even use ajaxed validation - although this would be overkill IMO.

BUT, bear in mind that javascript (or client-side) validation can be circumvented and you MUST back up this with server-side validation (PHP validation in your case).

HMTL5 comes with a set of pre-defined validation attributes and properties, like require, min, max etc.
