Question

      Input
      

        

Answer 1

I had the same problem with a hidden input field. Id i set the initial value on 0, it works fine, but sometimes i didn't want to have an initial value of 0. So i tested with value=" ", a whitespace, and it works for me too. If you fill the value dynamic from PHP you could do value="" if 0 is fine for you, or value=" " if a whitespace is fine.
