validation approaches

[Emerson Cargnin - MSA <em...@sicredi.com.br>]

What are u people using to validate form data in client and server without
rewriting code?  I know validator does that, although this approach doesn't
allows complex validation (as calculated validation digits). It looks like a
few people are using validator... (please correct me if I'm wrong)

Regards
Emerson

RE: validation approaches

[James Mitchell <jm...@telocity.com>]

I guess that depends on where you draw the line on customization.

If you can build a tool that handles your needs in a 'generic' fashion.
Then by all means, help us out and donate it.

However, if you app requires special validation handling, then customize the
app to do so.
