CakePHP 1.3 Application Development Cookbook

Overview of this book

CakePHP is a rapid development framework for PHP that provides an extensible architecture for developing, maintaining, and deploying web applications. While the framework has a lot of documentation and reference guides available for beginners, developing more sophisticated and scalable applications require a deeper knowledge of CakePHP features, a challenge that proves difficult even for well established developers.The recipes in this cookbook will give you instant results and help you to develop web applications, leveraging the CakePHP features that allow you to build robust and complex applications. Following the recipes in this book you will be able to understand and use these features in no time. We start with setting up authentication on a CakePHP application. One of the most important aspects of a CakePHP application: the relationship between models, also known as model bindings. Model binding is an integral part of any application's logic and we can manipulate it to get the data we need and when we need. We will go through a series of recipes that will show us how to change the way bindings are fetched, what bindings and what information from a binding is returned, how to create new bindings, and how to build hierarchical data structures. We also define our custom find types that will extend the three basic ones, allowing our code to be even more readable and also create our own find type, with pagination support. This book also has recipes that cover two aspects of CakePHP models that are fundamental to most applications: validation, and behaviors.

Preface

Implementing AJAX based pagination


The previous recipe, Paginating a custom find type, showed us how to paginate a custom find type. Each page link changes the browser location, forcing the reload of all the elements in the page.

This recipe allows us to use AJAX (using the jQuery javascript library) to only load what is really needed, so that every time a page is changed, only the set of rows is changed without having to load a whole new page.

Getting ready

We need some sample models and data to work with, and we need a fully working pagination of a custom find type. Follow the entire recipe, Paginating a custom find type, including its Getting ready section.

How to do it...

  1. 1. We start by adding the jQuery javascript library to our layout. If you don't have one already, create a file named default.ctp in your app/views/layouts directory. Make sure you add the link to the jQuery library (here we are using the Google-hosted one), the place holder for a loading message (to be shown when an AJAX...
