原文外掛簡介
The SDLC Country Block plugin lets you restrict access to individual posts and pages based on the visitor’s country, while keeping SEO bots and crawlers unblocked for safe indexing.
🔐 4 Layers of Country Detection
To ensure maximum compatibility, the plugin checks for the visitor’s country in this order:
1. Cloudflare header (CF-IPCountry)
2. Server GeoIP variables (if your hosting environment provides them)
3. PHP GeoIP extension (geoip_country_code_by_name)
4. Wordfence plugin (using Wordfence GEO detection)
⚠️ Note: At least one of these extensions or plugins must be enabled. If none are active, the plugin cannot detect visitor countries.
✨ Features
Per-post/page multi-select of countries (full ISO list)
SEO-safe: bots/crawlers can bypass blocks
Choose action: redirect to endpoint (/blocked), redirect to custom URL, or 403
Customizable endpoint slug
Role-based bypass (e.g., admin, editor)
Optional admin-only debug banner
Proper sanitization, escaping, and nonces
Sets Vary: CF-IPCountry for cache correctness
Clean uninstall (removes options and post meta)
