# Rethinking do_action(): Events as objects, hooks as class names

**[WordPress Developer](https://daily.dev/sources/wordpressdev)** · 13 min read · 2 upvotes · 0 comments

## Summary

A technique for improving WordPress action hooks by passing typed event objects instead of loose positional arguments. Using `do_action($event::class, $event)` gives you namespaced hook names via fully-qualified class names, IDE autocomplete and static analysis on payloads, and filter-like mutation through mutable object properties — all without any new dependencies. The approach mirrors the PSR-14 event dispatcher pattern and works with WordPress's existing hook API. The post covers event class design with readonly vs mutable properties, observer vs mutator listener patterns, and the tradeoffs between using class names vs fixed strings as hook identifiers.
