These are the most useful functions from the CFGP_U class for developing advanced solutions: working with REST keys, reading geo data, secure redirects, cache invalidation, bot detection, input sanitization, helper HTTP requests, and more. All examples are ready for copy/paste.
Tip: All methods are static (CFGP_U::method()), so you can call them directly from themes, plugins, or custom snippets.
Security Notes
- Do not output
KEY()and internal IDs in front-end HTML. - Use
CFGP_U::redirect()for redirects instead of manualheader()calls. - Trigger cache invalidation only when needed (e.g., after changing geo rules), not on every request.
- Do not apply geo rules to bots (
CFGP_U::is_bot()) to avoid breaking SEO previews and crawls.
