Adding Pagination

As we already know, the homepage of Quickwall shows all the questions that have been posted. This is a good thing, but what will happen when there will be many more questions? All the questions will be shown in the page, and as a result the page might be a big one! Also, it is not a good idea in terms of performance. One solution may be user paginations—so that all the questions are not shown together in a page, but divided into many pages.

Implementing pagination using CakePHP can be ridiculously easy. It is a default functionality in version 1.2.

Time for Action

  1. In the Questions controller, add the following variable:

    <?php
class QuestionsController extends AppController {
var $name = 'Questions';
var $paginate = array('limit' => 5, 'page' => 1, 'order' => array('Question.created'=>'desc'));
...
}
?>

  2. In the home action of the Questions controller, change the following line:

    <?php
class QuestionsController extends AppController {
...
function home() {
if...
