This is a bit of a weird request, so no surprise I haven't found any solution anywhere...
I'm using the Date Field option (DD/MM/YYYY) on multiple forms.
I need "00" to validate for the DD or MM and "0000" to validate for the YYYY
So if only a partial date is known.... 00/09/2012 or 00/00/2012 or 23/09/0000 would validate ok.
I had a look at Gform_validation but my attempts just break all validation :-/
Any help would be much appreciated...
