2. WordPress Execution Model

This module explains what happens when WordPress handles a request.

Lessons

• Request Lifecycle and Load Order — understand when plugins, themes, queries, and templates load
• Actions, Filters, and Hook Priority — modify behavior safely with hooks
• Conditional Tags, Rewrite Rules, and Query Vars — route requests without editing core

Core Principle

Do not edit WordPress core. Extend WordPress by using plugins, themes, child themes, hooks, template files, and documented APIs.
