How do I automatically format phone numbers on user input?

Digioh App Marketplace

There’s an app for that. You can have form input fields automatically format as phone numbers, so that it’s impossible for a user to enter a syntactically invalid phone number.

From the profile menu top right, select Custom JS (Apps), then install “Real-time phone number formatting (USA)”, one time for your account. All your boxes can now use the feature.

The input field rejects any input not a number, and automatically adds dashes to standardize.

To activate, select the specific phone number field in the Box Editor and at the bottom of the screen enter the metadata key “format_phone_usa”, with value “true”. The field must be of type Text, or be the built-in Phone field.
