customAttributes in Liferay

Steps to add customAttributes to user registration page:

* Click on control panel > User > Custom attributes > Add Custom attributes.
 * Here we need to give a key (name) and type of the field.
 * For eg. We will have an Field called Designation added which is a text field.

Key :   Designation

Type : Text-field(Indexed) and save.

* Then add the custom attribute taglib in the create_account.jsp in /tomcat/webapps/ROOT/html/portlet/login as follows:

< liferay ui:custom-attribute-list
            className="com.liferay.portal.model.User"

            classPK="<%= 0l %>"

            editable="<%= true %>"

            label="<%= true %>"

      />

  * But this field will not appear on the create account page because permissions are

 not given.

    * Hence to permission click on action tab of that custom attribute(here eg.Designation) and permissions



    * Here for guest we give permission for view and update.



    * Now in the create account page this field will appear.




TO ACCESS the custom fields in portlet

String Designation = (String)currentUser.getExpandoBridge().getAttribute("Designation").toString();
