Putting it all Together
You have seen how to create a Paginator object, how to render the items on the current page,
and how to render a navigation element to browse through your pages. In this section you
will see how Paginator fits in with the rest of your MVC application.
In the following examples we will ignore the best practice implementation of using a Service
Layer to keep the example simple and easier to understand. Once you get familiar with using
Service Layers, it should be easy to see how Paginator can fit in with the best practice
approach.
Lets start with the controller. The sample application is simple, and we'll just put
everything in the IndexController and the IndexAction. Again, this is for demonstration
purposes only. A real application should not use controllers in this manner.
select()->from('posts')->sort('date_created DESC');
// Create a Paginator for the blog posts query
$paginator = Zend_Paginator::factory($select);
// Read the current page number from the request. Default to 1 if no explicit page number is provided.
$paginator->setCurrentPageNumber($this->_getParam('page', 1));
// Assign the Paginator object to the view
$this->view->paginator = $paginator;
}
}

The following view script is the index.phtml view script for the IndexController's
indexAction. The view script can be kept simple. We're assuming the use of the default
ScrollingStyle.
paginator as $item) {
echo '' . $item->title . '';
}
?>
paginator; ?>
]]>
Now navigate to your project's index and see Paginator in action. What we have discussed
in this tutorial is just the tip of the iceberg. The reference manual and
API documentation can tell you more about what you can do with
Zend_Paginator.
