Join Carrie Dils for an in-depth discussion in this video What you should know, part of Advanced WordPress: Action and Filter Hooks.
- [Instructor] This course is designed for developers looking for a deeper understanding of how to work with action and filter hooks in WordPress. To get the most out of this course, I recommend that you're comfortable writing procedural code with PHP. You'll also want to be familiar with how to use WordPress, not necessarily as a developer, but as a regular user. Understanding the basics of how WordPress works, using the WordPress administrative dashboard, writing and publishing posts, etc. will give you a better context. It'll be helpful for you as you write plugins for WordPress.
If this is your first time working with WordPress at all, I'd recommend you browse through the WordPress essential training course to familiarize yourself with the software. In order to follow along exactly with this course, you'll need to have a code editor and WordPress installed and running locally. If you're unsure how to set up WordPress in your local environment, just go to the library and do a search for installing WordPress. You'll find numerous options based on your operating system and preferences and one of those courses can get you up and running.
Really, the only other thing you need for this course is a curiosity for experimenting with code and a willingness to break a lot of it in order to learn.
