Yes, you can use our Skeleton plugin to develop this:

- Download, install and enable skeleton plugin (you can download this at the end of https://www.easy-profile.com/docs/44-triggers.html )
- Edit file /plugins/jsn/skeleton/skeleton.php
- Remove example functions: triggerFieldAvatarUpdate, triggerProfileUpdate
- Add this function

triggerProfileUpdate($user,&$data,$changed,$isNew){ 

    $data['new_email_field_alias']=$data['email'];

}

replace "new_email_field_alias" with your duplicate email field alias

Now when user register or update his profile the email field is copied into new_email_field_alias field (located into #__jsn_users table)

NOTE: This code is not tested and supported

Thanks for the reply

=$data['email'];

does that bring across the email from the core user table?
Thanks
A

$data array contain the new values of the user.

You can read and write all new fields value before write on DB, only one limitation:
- $data contain Easy Profile field and Joomla User field, you can manipulate only Ep field, this because Joomla default field are written before that is trigger our plugin

Hi,
sorry this is not features of Easy Profile.

are you introducing this function?

in future yes, but we not have a timeline
