REGEX to check entries in form fields

hello, before to buy,
I'd like to know if form fields support REGEX to check the entries .
It's a must-have because I have to check user saler-ID-number and Belgian Phone number.

When booking is closed, can the organiser of the event receive automatically an email with all the attendance list (before the event session)?

Hello David

1. Unfortunately, the extension doesn't support custom REGEX to validate the custom field data

2. We don't have an option to email event organiser list of registrants. However, if the event is assigned to his account, he can login to your site, export list of registrants of that event

Regards,

Tuan
