Typically, a WordPress book consists of several chapters, each of them containing different practical examples to suit each section. In this book, our main goal is to learn how we can build full stack web applications using built-in WordPress features. Therefore, I thought of building a complete application, explaining each and every aspect of web development.
Throughout this book, we will develop an online portfolio management system for web development-related professionals. This application can be considered as a mini version of a basic social network. We will be starting the development of this application from Chapter 2, Implementing Membership Roles, Permissions, and Features.
Planning is a crucial task in web development, in which we will save a lot of time and avoid potential risks in the long run. First, we need to get a basic idea about the goal of this application, features and functionalities, and the structure of components to see how it fits into WordPress.
Developers and designers who work online as freelancers know the importance of a personal profile to show your skills for improved reputation. However, most people, including experts who work full-time jobs don't maintain such profiles, and hence get unnoticed among co-developers. The application developed throughout this book is intended to provide the opportunity for web professionals to create their public profiles and connect with the experts in the field.
This application will be targeted towards all the people who are involved in web development and design. I believe that both output of this application and the contents of the book will be ideal for the PHP developers who want to jump into WordPress application development.
Basically, our application consists of both frontend and backend, which is common to most web applications. In the frontend, both registered and unregistered users will have different functionalities based on their user roles. The following diagram shows the structure of our application home page:
The backend will be developed by customizing the built-in admin features of WordPress. Existing and new functionalities of the admin area will be customized based on the user role permissions.
Application consists of four user roles, including the built-in admin role. User roles and their respective functionalities are explained in the following section:
Admin: This manages the application configurations, settings, and capabilities of the users.
Developer: This is the user role common to all web professionals who want to make profiles. All the developers will be able to create complete profile details to enhance their reputation.
Members: These are normal users who want to use the things created by developers and designers. They will be able to access and download the work made public by developers. Basically, members will have more permission to directly interact with developers, compared to subscribers. Also, we can implement premium content section in future for paid members.
Subscribers: These are also normal users who want to follow the activities of their preferred developers. These users will be notified whenever their preferred developers create a new activity within application.
Our main intention of building this application is to learn how WordPress can be adapted to advanced web application development. Therefore, we will be considering various small requirements, rather than covering all aspects of a similar system. Each of the functionalities will be focused on explaining various modules in web applications and the approach of WordPress in building similar functionality.
Let's consider the following list of functions, which we will be developing throughout this book:
Developer profile management: Users who register as developers will be given the opportunity to construct their profile by completing content divided into various sections such as services, portfolio, articles, and books.
Frontend login and registration: Typically, web applications contain the login and registration in the frontend, whereas WordPress provides it on the admin area. Therefore, custom implementation of login and registration will be implemented in the application frontend.
Settings panel: Comprehensive settings panel will be developed for administrators to configure general application settings from the backend.
XML API: A large number of popular web applications come up with a fully functional API to allow access to third-party applications. In this application, we will be developing simple API to access the developer details and activities from external sources.
Notification service: A simple notification service will be developed to manage subscriptions as well as manage updates about the application activities.
Responsive design: With the increase of mobile devices in Internet browsing, more and more applications are converting their apps to suit various devices. So, we will be targeting different devices for fully responsive design from the beginning of the development process.
Third-party libraries: Throughout the book, we will be creating functionalities such as OpenAuth login, RSS feed generation, and template management to understand the use of third-party libraries in WordPress.
While these are our main functionalities, we will also develop small features and components on top of them to explain the major aspects of web development.
