Text match plugin

I am using the text match plugin to validate a phone number to ensure that it starts with a zero (True).

How do I prevent submission of the form if the result is False?

If you use the native form, you can only create a message/hint. However, to prevent the form from being submitted, you will need custom CSS.

Another alternative is to use a custom form and enforce conditions through a custom action on your submit button.

That is brilliant. I think hint will be OK for now

An alternative for you is using Twilio’s Lookup API.
