Answer 1

Yes, you can use Custom Attributes functionality for liferay entities (in your case, User) and can add as many extra fields as necessary for each liferay entity.

Custom field for the user-entity can be created through:
Control Panel -> Portal -> Custom Fields -> User.

And programmatically can be created as follows:

user.getExpandoBridge().addAttribute("yourCustomFieldKey");

Then set the value as:

user.getExpandoBridge().setAttribute("yourCustomFieldKey", "valueForCustomField");

If your custom field is already present you can check like this:

if (user.getExpandoBridge().hasAttribute("yourCustomFieldKey")) { ... };

The data is stored in tables prefixed with "EXPANDO":

• EXPANDOCOLUMN: stores the custom field key and other settings (contains the tableId refrences)
• EXPANDODATA: stores the custom field value for the key (contains the columnId and tableId refrences)
• EXPANDOTABLE: stores for which liferay entity (user) are you adding the custom field
• EXPANDOROW: stores linking information between a user and its values (contains tableId and userId refrences)

Hope this helps.

Answer 2

yes, you can add custom fields to user-entity and add them the field-values to user:

user.getExpandoBridge().addAttribute(...);

Custim field for the user-entity you can create by Control Panel Portal->Custom Fields or programmaticaly at liferay start.

The data will be stored in ExpandoValue tables.
