[Zope] How to check if a string contains some characters??

[David Burton]

A better idea would normally to try to handle invalid values before it
reaches ZOPE.
Something like this is usually best handled by Javascript verification.

You can take this too far (one form page given to us by a design company had
well over 100K of Javascript validation text), but if the system is going to
be handled over the web, using Javascript is a lot faster than detecting
this server-side. It saves on the server hits too.

Save the server validation for checking for duplicate entries, etc.

If you need a sample of validating a form like this, let me know.

Yours,
David Burton
