Hello! Welcome to the WordPress development course. This is the most comprehensive and effective course on WordPress development around. This is the only course you'll ever need to learn WordPress development. 

WordPress currently holds over 30% of the market share on the web. WordPress is an absolute dominant force and it's popularity continuously grows. One of the best things about WordPress is that it's easily extendable. There are thousands of plugins and themes available both free and premium.

In this course I will teach you how to create your very own plugins and themes. This course was designed for those who truly want to master WordPress inside and out. There is no stone left unturned. This course will help make you into one of the most competitive WordPress developers out there. You will be able to develop custom plugins and themes no matter how hard the task is.

You can expect high quality and fresh tutorials. This course uses the latest versions of software development including PHP (7.x), Twitter Bootstrap (3.x), MySQL/MariaDB (5.x) and, Vue.js (2.x) . 

Here is an overview of what you can expect to learn.

  • Take a static HTML bootstrap template and convert it into a fully functioning WordPress theme. 
  • Extend the functionality of your theme by using the WordPress customizer API. Work with the various fields you can create from simple text fields to the color picker and file uploader.
  • Write code that scales and learn the best practices for writing clean, efficient, secure and reusable code. The WordPress coding standards are covered from PHP to JavaScript and CSS.
  • Properly take advantage of the template hierarchy system and create your own custom templates for more unique designs.
  • Build your own custom widgets to display your own content.
  • Build plugins that extend the core functionality of WordPress.
  • Develop custom post types for content that give you the flexibility to curate content you want to. Apply meta data to your content and display everything on the front end.
  • Learn about the various methods for creating your own custom admin forms and process the data securely.
  • Want to learn about WooCommerce and BuddyPress development? That's covered too! The theme we create will be full compatible with these 2 plugins and we'll even customize the look and feel to suit our needs.
  • Other topics include licensing, translations, security, transients, authentication, front end publishing, shortcodes and so much more!
  • The APIs that are covered are the following: Dashboard widgets, API, Database API, HTTP API, Metadata API, Options API, Plugins API, REST API, Rewrite API, Settings API, Shortcode API, Theme Modification API, Transients API

In a nutshell, we'll explore the various WordPress APIs and how they should be used. The codex page is filled with examples and each page is quite lengthy. WordPress development doesn't have to be hard to learn. The biggest mistake most coding tutorials make is expecting someone to learn simply by imitating others' code. Real world situations are never exactly like the tutorial.

I believe the best way to learn is to understand how a tool works and what it does for you, look at examples, and then try it yourself. That's how this course is built, with the goal to help you both learn and understand WordPress.

Take the leap into Single Page Application Development

This course goes beyond the simple WordPress plugin development and WordPress theme development tutorials. You will learn how to create single page applications with WordPress as the back end. The CEO of WordPress, Matt Mullenweg, has urged developers to start learning JavaScript deeply

You will first learn the basics such as the command line and ES6. You will be caught up with the latest standards of JavaScript from modules to destructuring and so much more! Tools such as babel and webpack are also explored and implemented with our code. We will build a functioning WordPress single page application theme using Vue.js

Vue.js is the most developer friendly and flexible framework for building single page apps. Build components to separate your code and wire up your own custom routes for a better user experience. All this knowledge right at your fingertips!

Why am I qualified to teach this course?

I've been developing sites in WordPress for over 6 years. I know all the tricks to working with WordPress. I don't fool around. You will learn all my techniques and the teach you the exact process I go through. I currently sell premium commercial themes and plugins with over 1000+ sales worldwide. I know what it takes to create stuff that works!

There's a lot of money to be made with this industry and I will show you how. You will also be taught how to sell your plugin online and make a profit. This includes licensing and learning about the various platforms out there to help you with marketing.

You'll have the skills and confidence to build your own custom themes and plugins your clients will love. You'll be able to take on bigger projects for more money. Don't believe me?
