Roadmap: how to learn WordPress development

1. Learn the basics of the web

Start with HTML and CSS. You need them for every theme and design change. Then learn basic JavaScript.

2. Learn WordPress as a user

Install WordPress locally (with tools like LocalWP) or on cheap hosting. Learn posts, pages, menus, widgets, the block editor, users and settings.

3. Learn PHP basics

WordPress is written in PHP. Learn variables, arrays, functions, loops and conditions. Then learn WordPress concepts like The Loop, hooks (actions and filters) and template hierarchy.

4. Customize and build themes

Create a child theme of a lightweight theme like GeneratePress, edit templates and styles, and then try building a simple theme from scratch. Learn block themes and theme.json, which modern WordPress uses for full site editing.

5. Build plugins

Start with a small plugin: a shortcode, a custom post type or a settings page. Learn the REST API, security basics (sanitising, escaping, nonces) and how to keep code compatible with updates.

6. Speed, SEO and security

Learn caching (LiteSpeed Cache), image optimisation (WebP), SEO plugins (Rank Math, Yoast), backups (UpdraftPlus) and security best practices. Clients pay well for these.

7. Use AI tools to learn faster

AI assistants can explain code, write starter functions and help debug errors. Use them to speed up learning, but always read and test the code yourself before using it on a live site.

8. Build a portfolio

Create 3–5 real projects (a blog, a business site, a small plugin) and show them on your own website. A portfolio wins clients faster than certificates.
