CakePHP 1.3 Application Development Cookbook

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.

Building queries with ad-hoc JOINs

CakePHP has a very easy way to handle bindings, and through the use of the Containable behavior, as shown in several recipes in Chapter 2, Model Bindings, we have a lot of flexibility when dealing with bindings.

However, there are times where we need to fall outside of a normal find operation and perform queries that join several models, without using normal binding operations, to save us some valuable queries. In this recipe, we will see how to specify JOIN operations when performing a find on a model.

Getting ready

We need some sample models and data to work with. Follow the Getting ready section of the recipe, Performing GROUP and COUNT queries.

To illustrate the difference between normal binding operations and what is shown in this recipe, we need the Containable behavior. Create a file named app_model.php and place it in your app/ folder, with the following contents. If you already have one, make sure that, either you add the actsAs property shown as...
