Can I stop customers entering speech marks at the checkout?

[jonsurf]

Hi

I'd like to be able to prevent customers from entering speech marks in any of the fields at the checkout. This could be from disabling the " key or by means of some kind of validation. Can anybody suggest how to do this please?

The reason for this is that speech marks in customer input causes problems with our 3rd party ERP software, which isn't easy to change at their end.

Many thanks

Jon

A little bit of javascript validation would do it. As an example of something similar you could look for the threads on postcode formatting or name and address capitalisation scripts.
