Common questions
When should I use a code snippet instead of a plugin?
When the change is small, specific, and easy to maintain, especially if another plugin would be unnecessary overhead.
Where should code snippets go?
In a custom plugin, theme functions file, or site-specific mu-plugin when they should stay active regardless of theme changes.
Are code snippets safe for beginners?
Only if you understand what the code does and have a recovery path. A bad snippet can break admin access.
What makes a snippet maintainable?
Clear scope, minimal side effects, capability checks, sanitization, and using the right hook at the right priority.
