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>

<li>Server GeoIP → Your hosting provider must support GeoIP (ask your host if they provide <code>GEOIP_COUNTRY_CODE</code>).</li>
<li>PHP GeoIP Extension → Install and enable the PHP <code>geoip</code> extension on your server (may require server admin/hosting support).</li>

IP Locator is a country and language detection tool for WordPress. It is fast, reliable and plug & play.
It can detect and render the country, the main language and the country flag of each visitor of your site. It provides:
<ul>
<li>a strong, accurate and ultra-fast IP and country detection;</li>
<li>many shortcodes to display country names, languages and flags (emoji or vectorized);</li>
<li>a shortcode to conditionally hide or show strings or other shortcodes;</li>
<li>a CSS modifier to add a country-specific class to the <code>body</code> tag of your site;</li>
<li>an automatic system to be always up to date (no API key, no IP data files to manually import);</li>
<li>a full-featured API for plugins / themes developers.</li>
</ul>
For full details, you can browse <a href="https://github.com/Pierre-Lannoy/wp-ip-locator/blob/master/SHORTCODES.md" rel="nofollow ugc">the shortcodes list</a> or <a href="https://github.com/Pierre-Lannoy/wp-ip-locator/blob/master/DEVELOPER.md" rel="nofollow ugc">the API description</a> (for developers).
IP Locator can be used too to report the following main items and characteristics:
<ul>
<li>KPIs: number of detected countries and languages, accesses breakdown and detection ratio;</li>
<li>countries for real humans with public IPs;</li>
<li>languages for real humans with public IPs;</li>
<li>metrics variations;</li>
<li>metrics distributions;</li>
<li>full list of countries per channel;</li>
<li>full list of countries per client (requires the free <a href="https://wordpress.org/plugins/device-detector/" rel="ugc">Device Detector</a> plugin).</li>
</ul>
Technically, IP Locator:
<ul>
<li>works on dedicated or shared servers;</li>
<li>can detect the source IP even behind proxies or load-balancers;</li>
<li>can use AWS CloudFront, Cloudflare and Apache mod_geoip to speed-up detection;</li>
<li>natively supports APCu caching(1) and all other dedicated object caching mechanisms, like Memcached or Redis;</li>
<li>has a minimal footprint in the page rendering time;</li>
<li>runs its data updates in background, without impact on the website speed;</li>
<li>is fully compatible with multisites;</li>
<li>natively supports names and languages localizations(2).</li>
</ul>
(1): <a href="https://www.php.net/manual/en/intro.apcu.php" rel="nofollow ugc">APCu</a> needs to be activated on your server if you want to use it in IP Locator.
(2): <a href="https://www.php.net/manual/en/intro.intl.php" rel="nofollow ugc">PHP Intl extension</a> needs to be activated on your server if you want to use it in IP Locator.
