SDLC Corp

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.
<h3>🔐 4 Layers of Country Detection</h3>
To ensure maximum compatibility, the plugin checks for the visitor’s country in this order: 
1. Cloudflare header (<code>CF-IPCountry</code>) 
2. Server GeoIP variables (if your hosting environment provides them) 
3. PHP GeoIP extension (<code>geoip_country_code_by_name</code>) 
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.
<h3>✨ Features</h3>
<ul>
<li>Per-post/page multi-select of countries (full ISO list)</li>
<li>SEO-safe: bots/crawlers can bypass blocks</li>
<li>Choose action: redirect to endpoint (/blocked), redirect to custom URL, or 403</li>
<li>Customizable endpoint slug</li>
<li>Role-based bypass (e.g., admin, editor)</li>
<li>Optional admin-only debug banner</li>
<li>Proper sanitization, escaping, and nonces</li>
<li>Sets <code>Vary: CF-IPCountry</code> for cache correctness</li>
<li>Clean uninstall (removes options and post meta)</li>
</ul>

Advanced Country Blocker helps you secure your WordPress site by restricting access based on the visitor’s geolocation (country) or IP address. Upon activation, the plugin detects the activating admin’s country and automatically sets that as the only allowed country. All other visitors from different countries are blocked, unless they use a secret key parameter to temporarily whitelist their IP. Country detection uses the privacy-friendly ip-api.com service by default but can be switched to a fully offline MaxMind GeoLite2 (or compatible) database file once you configure a local copy.
Key Features:
<ul>
<li>Automatically allows the admin’s country on plugin activation.</li>
<li>Flexible IP-to-country lookups – start with the built-in ip-api.com integration and optionally switch to an offline MaxMind GeoLite2 Country (or compatible) <code>.mmdb</code> database file.</li>
<li>Allowlist or blacklist mode – choose whether the country list acts as an allowlist or blocklist without re-entering countries.</li>
<li>Temporary access via a customizable secret URL parameter (e.g., <code>?MySecretKey=1</code>).</li>
<li>Manual blacklisting and safelisting of IPs for added security and to accommodate uptime monitors.</li>
<li>Optional email alerts when new visitors are blocked.</li>
<li>Admin bypass so logged-in admins can always access the site (toggleable in the code).</li>
<li>Detailed logging of blocked attempts in a custom database table, displayed in the WP admin.</li>
<li>Custom response controls – personalise the block page title/message, choose the HTTP status (403, 410, 451) or redirect to any URL.</li>
<li>Automatic log cleanup with configurable retention plus a one-click “Clear Logs” button.</li>
</ul>
Use the plugin settings page (Country Blocker menu in WP admin) to configure the list of allowed countries, blacklisted countries, blacklisted IPs, and whether email alerts are enabled.

<h3>External Services</h3>
By default this plugin contacts the ip-api.com geolocation service to detect visitor countries. You can disable all external lookups by switching the IP lookup method to the local MaxMind database in the settings.
