Feature Request | Country/User based Targeting Option for All Types of Notifications

[ShahrearMSf]

Country- and user-role-based targeting previously lived inside the PressBar extension and was enforced only in the Notification Bar type — so it worked only for the bar, and only while the bar module was enabled. This PR decouples targeting into a shared core system so every notification type gets it, and closes the gaps needed to make it production-ready.

Feature Request | Country/User based Targeting Option for All Types of Notifications

What's in this PR

1. Decouple targeting from the bar module (Core\Targeting)
   • Registers the Targeting section (Country Targeting + Set Target Audience) on the shared nx_customize_fields schema, so it appears for all types (excludes only GDPR + Exit Intent, mirroring the core appearance rule).
   • Enforces via the single global nx_show_on_exclude filter (FrontEnd::get_notifications_ids()), so it applies to any notification regardless of active modules.
   • Removes the old bar-only field registration (PressBar) and enforcement (NotificationBar).
   • Routes the country-search AJAX by field (REST → Targeting::restResponse), fixing search for all types.
2. Add a "Logged-out Visitors (Guests)" audience option — the enforcement already honored guest, but it was never selectable, so logged-out visitors could only be excluded, never targeted alongside roles.
3. Cache the visitor-country geo lookup — since targeting now runs for all types, the ip-api.com lookup could fire on many more page loads. The free tier is rate-limited by the server IP (shared across all visitors), so an uncached call would hit 429s and wrongly hide country-targeted notifications, plus add blocking latency. Now:
   • request-level memo (resolve once per page load),
   • per-IP transient cache for successful lookups (default 12h, filterable),
   • host/CDN header shortcut (CF-IPCountry, GEOIP_COUNTRY_CODE, X-Country-Code) to skip the external call entirely where available,
   • bounded 3s timeout, cache only on HTTP 200, failures retry,
   • filters: nx_visitor_country_code (override/mock) and nx_visitor_country_api.

Files changed

• includes/Core/Targeting.php (new) — fields + enforcement + REST handler
• includes/Core/REST.php — route country search by field
• includes/Core/Helper.php — cached nx_get_visitor_country_code()
• includes/NotificationX.php — boot Targeting::get_instance()
• includes/Types/NotificationBar.php, includes/Extensions/PressBar/PressBar.php — remove bar-only targeting
• languages/notificationx.pot, vendor/composer/autoload_*.php

Testing

Free-only change (Pro needs none — is_pro fields unlock via Pro's generic mechanism; verified no targeting code in Pro).

Test	Where	Result
Role: all_users / admin / subscriber / guest / guest+admin	Local (deterministic)	✅ correct show/hide
Country match logic	Local (spoofed IP → real geo)	✅ [US] shows, [BD] hides
Country enforcement — real geo	Live (Cloudflare host, visitor BD)	✅ US → hidden, BD → shown
Targeting fields render + editable for all types	Live (Notification Bar Customize)	✅ incl. Guest option
Pro is_pro field saves	Live (is_pro_active)	✅ persists
Geo caching	Local (transient) + Live (CF-IPCountry)	✅ external call cached / skipped
Build health, php -l, fatals	Local + Live	✅ clean

Notes

• On Cloudflare/GeoIP hosts the external geo call is eliminated entirely via the header shortcut; elsewhere it's cached per IP.
• GDPR + Exit Intent are intentionally excluded from targeting.
