Hooking code in WordPress involves utilizing actions and filters, two types of hooks that allow you to modify or add functionality without altering the core files. Actions are used to execute code at specific points during WordPress execution, while filters allow you to modify data before it’s sent to the database or browser.
To use a hook, you need to define a function and then attach it to a specific action or filter using the `add_action()` or `add_filter()` functions, respectively. Your function can then add, remove, or modify functionality or data. It’s important to choose the correct hook that corresponds to the specific event or location in the WordPress execution flow. Remember to use priority and arguments effectively to control when and how your function executes in relation to other hooked functions.
