I'd like to get some feedback on form validation. In my organization (major
insurance company), it is necessary to validate the following fields:
For existing and new customers:
- first name (letters only)
- last name (letters only)
- address
- city (only letters)
- state
- zip (only
I would highlight the field that fails validation and I'd put the
following message next to it:
This doesn't look like a [first name|last name|city]. Maybe you made
a spelling mistake?
This should be OK for users that just accidentally pressed a number
key when they were typing. Of course in

Thanks for the comments about the form

to your efforts at understanding Norwegian :-). I'll make a quick
attempt at answering your points:
There is definitely an issue with the telephone number. It's

I feel that having inline form validation is the best way there is. I
use a combination of generating a great form with pform (http://
www.phpform.org/) and using a php/ajax form validation library. there
are plenty of them around. But this can be a nice, and pleasing
experience to the person
I agree with Caroline on the need for UIs to exercise sufficient restraint
when people are entering data.
When designing interactions on web pages, I often refer to a little guy I
keep in my head, who's a concierge in a high-class hotel, and imagine how
he'd behave.

I'm with Caroline - Mint is disturbing!
I was experimenting with error fields and after some debate decided
to do it this way (granted this form is simple, sorry about the

Hi Maxim,
Please see Robert Hoekman Jr.'s book, *Designing the Obvious*. Chapter 5. He
goes into great detail regarding form design validation, the art of
setting good form defaults, and how to write effective error messages ( how
to keep errors from occurring in the first place). I'll never look
I would highlight something Bryan said above. Back end error checking
is important, but why not use some front end JavaScript to check for
simple things like blank fields.
With unobtrusive JavaScript you can set a script up once and apply it
to all your forms easily.
You can see an example here:

I've watched users working with forms like this. My concern
I gave the mint.com site a try and agree with your colorful remarks about
its effect on the experience =]. I've designed dozens of such forms with
validation on the previous field and feel the same as you - it's a good
start but feels like it could be better.
