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

Using behaviors to add new fields for saving


In the recipe Using callbacks in behaviors we learnt how to implement different model callbacks to perform some tasks automatically. In this recipe we will continue that process and we will learn how to automatically save data that may not be provided in a save operation.

We will use the Twitter example we have been using in this chapter, so that when a profile is saved, its Twitter URL and its last tweet are saved when creating a new record, or when updating an existing one.

Getting ready

We need a working TwitterAccountBehavior together with its controllers, models, and views. Follow the recipe Using callbacks in behaviors (there's no need to enable caching in the behavior, so you can omit the There's more section).

Add two fields to the profiles table, url and last_tweet, by issuing the following SQL command:

ALTER TABLE `profiles`
ADD COLUMN `url` VARCHAR(255) default NULL,
ADD COLUMN `last_tweet` VARCHAR(140) default NULL;
