{form_relationship} Controller The profile information controller (controllers/profile/ profileinformationcontroller.php) needs to communicate with the model, to get the data for the profile, and have the data assigned to template variables We already have a method in the controller to this, so it should be a fairly trivial task: include the model, and call the toTags method to push the profile information to template tags, as highlighted in the code below: Template The template for this aspect of the profile is shown below (views/default/ templates/profile/information/view.tpl.php); the highlighted aspects show the common template information shared by all aspects of the profile (including aspects we may add in the future) Friends
