Hi,

We have the phone numbers formatted as (123) 456-7890;ext=12

I would like to show an error if the phone number contains any other non numbers or special characters. Please advise the code on how to achieve this?

Thanks.

RE: Phone number validate

Hi,

You can create or use a PCF. See pcf.gallery/.../ for example. A regular expression like \(\d{3}\) \d{3}-\d{4};ext=\d{2} should works.

Or you can write a javascript code that check the format with a regex:
const invalidPhoneNumberNotif = "INVALID_PHONE_NUMBER_FORMAT"; function checkPhoneNumberFormat(execCtx) { const formCtx = execCtx.getFormContext(); const phoneNumberAttr = execCtx.getEventSource(); const phoneNumberCtrl = formCtx.getControl(phoneNumberAttr.getName()); const phoneNumber = phoneNumberAttr.getValue(); const phoneNumberRegex = /\(\d{3}\) \d{3}-\d{4};ext=\d{2}/; if (phoneNumber != null && !phoneNumberRegex.test(phoneNumber)) { phoneNumberCtrl.setNotification("Phone number format must be (123) 456-7890;ext=12", invalidPhoneNumberNotif); } else { phoneNumberCtrl.clearNotification(invalidPhoneNumberNotif); } }

Add this javascript function to the "on change" event of your phone number fields. Ensure to check "Pass the execution context as first parameter".

If ;ext=12 is optional, you will need to adapt the regex. You can test/adapt the regex here: regex101.com/.../1

RE: Phone number validate

Thanks Xavier, this really helps. In the case where if I would like to allow the phone number EXTENSION maximum from 1 to 10 numbers after ext=, how do I do that in regex? Please advise

For example, I want the user to allow the phone number (123) 456-7890;ext=12345 or (123) 456-7890;ext=123412 or (123) 456-7890;ext=12345897

RE: Phone number validate

In this case, the regex will be \(\d{3}\) \d{3}-\d{4};ext=\d{1,10}

See the regex in action: regex101.com/.../3
