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.

It is really interesting that we can have three resources that aggregate and display the blogs belonging to one of the three categories that we have defined. This alone can be useful for showing the recent posts of a site from each category. However, this can be extended further to be more useful, by allowing these resources to render the content in a way that machines understand. We want the content to be processed and displayed by other websites or to be read by the news feed readers.

Machine-readable formats and readers

XML is about generating document definition tags on the fly and placing the data within such tags. Unlike HTML, there is no fixed set of such tags. Hence, to make sense of such tags, the machine reading them must have some prior knowledge of what those tags mean. Groups of such definitions in a specific order and convention are called Formats. We have many such formats that are commonly used for sharing data. We also have what are called Readers. Readers are...
