Re: [Zope] Validating data entry (dates)

10 Dec 1999


      Hi Jens,
...
my suggestion for data validation *before* submitting the form would be
javascript. (is that blasphemy??? ;)
Blasphemy no (for me at least;) I was hoping that i could avoid Javascript.
Mixing DTML and Javascript for such
a simple task  seems to me a bit messy.
...
DTML is interpreted on the server, so you would not be able to validate
using DTML without sending the data back to the server...
Shame om me, that's something I completly overlooked. That said it would be
nice if you can evaluate the outcome of a form submit, trapping errors.
Something like (Delphish pseudocode):

 if form.submit.errocode <> 0 {an error accured) then
 begin
  case errorcode of
   begin
     00001: ShowMessage('InvalidDate');
   end;
 end
