MODx Web Development - Second Edition

Overview of this book

MODx is a content management system and PHP web application framework rolled into one. With the ease of a CMS and the extendibility of a framework, MODx allows you to develop professional-looking, intricate websites with its easy-to-use interface and flexible architecture. MODx provides reusable code fragments called snippets, most of which are so generic that, without any modification, they can serve multiple functionalities. The generic nature of the snippets makes it possible to get the perfect customization that is so hard in other CMS. This book will get web developers up-and-running with MODx. With step-by-step examples and illustrative screenshots, you will be guided through installation, configuration, and customization. By the end of the book, you will have created a powerful, dynamic website by using the individual elements of MODx, without the need for programming know-how. Starting with a walk-through of how to install MODx, you will quickly learn how to develop your site without having to use any programming language. Logical, step-by-step instructions will show you how to create your own unique site by adding and editing documents using the inbuilt TinyMCE editor. You will change the look and feel of your site by creating your own templates using HTML, CSS, and widgets. By following the example of a blog site, you will learn how to extend your templates to allow rich user interactions through comments, posts, and forms. The book teaches a few code snippets such as Ditto and Wayfinder in detail. These powerful and flexible snippets will enable you to add multiple functionalities to your site. The book will also introduce you to many more snippets that will help you build some of the commonly required web functionalities such as forums and image galleries. You will manage your users with authentication and authorization and make your site user-friendly with user groups, forums, and the use of PHx notations to embed logic in templates. Through following this easy-to-use, step-by-step guide you will, by the end of the book, have a fully functional, feature-rich MODx site with professional-looking, dynamic web pages that are totally customizable.

The basic element of MODx: Resources


Resources are the basic building blocks in MODx. They are the elements that make up the content of the site. Every web page in MODx corresponds to a Resource page. In early versions of MODx, Resources were called Documents. Thinking of them as documents may make it easier for you to understand. Every resource has a unique ID. This ID can be passed along in the URL, and MODx will display the page for the resource with the same ID. In the simplest case, a resource contains plain text.

As can be seen from the previous screenshot, the ID referred to here is 2, and the content displayed on the screen is from resource ID 9. It is also possible to refer to a resource by an alias name instead of an ID. An alias is a friendly name that can be used instead of having to use numbers. Aliases will be explained in more detail later in the book.

Containers

Resources can be contained within other resources called containers. Containers in MODx are like folders in filesystems...
