ZIP Code user verification

[musqsim]

Hi everyone!

I want to verify if user zip code is in XXXX-XXX format, (where X is ONLY NUMBER)...

Something like this: http://html5pattern.com/

How and where can I do it?

Thanks in advance!

it can be done by javascript and you can use the tutorial below.

just add the field id whatever zip gets in the html and use it.
