Description

WordPress is the hottest CMS available on the web.There are hundreds of jobs posted each day online with clients seeking WordPress developers. It's popularity is due to the fact that there are thousands of plugins and themes available online. There's a lot of money to be made with this industry and I will show you how.

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.

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.

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.

Who is the target audience?
  • Web Developers
  • Web Designers
  • PHP Coders
  • Entrepreneurs
  • Users who would like to make money online selling plugins and themes
  • This course is for students who are new to developing plugins and themes and would like to learn the best practices for developing themes/plugins.

Web development is passion of mine. I've helped several businesses by taking their products and services online. I love to teach others the best practices for web development and provide free resources and tutorials on my own persona blog.
