Joomla!'s core content management has a built-in feature where visitors are able to send articles to their friends through email. A similar feature can be added to the "Restaurant Reviews" component. The component can be modified to display a link to a form where the email address of a friend can be entered along with a short message.

We will create a new view to handle this form. Go to the /components/com_restaurants/views folder and create a new folder named email. In this folder, create a file called view.html.php, and load it with the following code:

<?php
defined( '_JEXEC' ) or die( 'Restricted access' );
jimport( 'joomla.application.component.view');
JTable::addIncludePath(JPATH_COMPONENT_ADMINISTRATOR . DS . 'tables');
class RestaurantsViewEmail extends JView
{
function display($tpl = null)
{
$id = JRequest::getInt('id', 0);
$review =& JTable::getInstance('review', 'Table');
$review->load($id);
$this->assignRef('review', $review);
parent::display($tpl);...
