Prevent users entering non acceptable symbols

[mcinik]

Our payment provider will not accept certain symbols in fields e.g full stop in contact telephone number field. How do I prevent non acceptable alpha, numeric or symbols being entered in fields. Nikki

You would need to use some custom Javascript to do the validation, probably a much bigger and technical task than you might realise. Each field could need its own rules set, i'm guessing you have no JS experience, so it'd be a case of trawling Google and finding some code via a Javascript library or perhaps contacting a developer to do this for you.

Probably cheaper and easier to just change PSPs, who is it setting these rules?
