About This Solution

This snippet generates a new custom field on the registration form which asks the user to confirm their email address (enter it a second time). By asking the user to confirm their email address, mistakes a minimised by the user, meaning they are less likely to miss out on emails and other communications. If the confirm email address field is left empty upon registration, an error appears letting the user know it is a required field. If the new field is populated, by isn’t identical to the billing email field, an error appears letting the user know the email addresses do not match.
