Form fill - overwrite fields when the values are blank

with some mktoForm js you could change the field values to be "NULL" on submit if the field value is empty

To achieve this:

you can set default values.

or

    The problem with simply setting the value to NULL using JS (and it's even more obvious if you set a default value) is the user sees the word NULL, which looks unprofessional IMO.

      Ah yes, I admit I forgot that the form field is still visible for a split second when you change values that way.

       

      I would then probably just use js to add hidden fields for the fields that are empty and set the values of those to NULL. It might be hacky but I think it should work.

      That'll work fine, though requires a proxy for every field that might be blank-able. I think you'll like my technique when it comes out.
