Perl expression format checking broken with latest release!

Hello, I have had Perl Regular expression checking for fields such as Phone Numbers working for many releases. This latest release has stopped them from working. Because of that, no record can be saved in the back-end. Once they are removed, all work fine.

This is what I've always used for phone number validation:
Can anyone assist with a fix?

Works perfectly fine in all my tests. Ensure you've CB 2.0.13 installed. Your REGEXP is missing delimiters as well, which you must supply. The below is 1:1 more about what you should be using.


This will match the following exactly.

111-1111
111-111-1111
(111) 111-1111

If still not working check that your browser is up to date or try a different browser as the JS regex parsing is a different engine from PHP regex parsing and an out of date browser may not be able to parse some usages. This means you need to be careful to ensure your REGEXP is JS and PHP compatible.
