Alternative User Emails

This module stores alternative email addresses for users, in addition to the single primary email address stored in the user's mail field.

This can be useful for preventing duplicate users being created for people who have multiple email addresses, as most of us do.

What it does

• A multi-value field called 'alternative_user_emails' is added to the user entity type.
• When the primary email is changed, the old email is automatically added to the alternatives.
• User entity queries are altered so that queries that filter by the mail field also filter by the alternatives.
• Validation ensures that mails and alternatives are unique to a user.

Recommended modules

• Read-only widget is useful if you wish to show the alternative emails on a user form, but not allow them to be edited.

Related modules

• Multiple E-mail Addresses is a much more ambitious and feature-rich approach to allowing multiple email addresses for users. It is now available for Drupal 8+. However, it does not modify user queries in the way this module does.
