Show Geo Content by Visitor IP in WordPress

Design goal

For “Show Geo Content by Visitor IP in WordPress”, the page must remain useful before the IP request finishes. The geo result is an enhancement: it is validated, applied to one narrow decision, and discarded when it is incomplete.

Request and decision flow

Show Geo Content by Visitor IP in WordPress: The flow below is specific to this implementation rather than a generic IP lookup checklist.

1. Step 1: Render complete default copy in PHP; JavaScript may replace only the small regional note. shortcode fallback HTML
2. Step 2: Generate a unique DOM id for every shortcode instance and load the script once. wp_unique_id + static guard
3. Step 3: Use AbortController and response.ok before reading JSON. 2.5s timeout
4. Step 4: Validate a two-letter country code and cache it only for the browser session. sessionStorage
5. Step 5: Fire a custom event so analytics can measure fallback and resolved states separately. ipin:geo-content

Production-oriented example

Show Geo Content by Visitor IP in WordPress: This example adds a timeout, response validation, a deterministic fallback, and framework-specific lifecycle handling.

<?php
function ipin_geo_content_shortcode(): string {
    $id = wp_unique_id('ipin-geo-');
    $default = 'Support is available through our global help center.';
    return sprintf(
        '<aside id="%s" class="ipin-geo-note" data-default="%s">%s</aside>',
        esc_attr($id), esc_attr($default), esc_html($default)
    );
}
add_shortcode('geo_content', 'ipin_geo_content_shortcode');

function ipin_geo_content_assets(): void {
    wp_register_script('ipin-geo-content', '', [], null, true);
    wp_enqueue_script('ipin-geo-content');
    wp_add_inline_script('ipin-geo-content', <<<'JS'
(() => {
  if (window.__ipinGeoContentLoaded) return;
  window.__ipinGeoContentLoaded = true;
  const copy = {
    JP: 'Japan support: weekdays 09:00–18:00 JST.',
    DE: 'EU support: weekdays 09:00–17:00 CET.',
    US: 'US support: weekdays 09:00–17:00 ET.'
  };
  async function country() {
    const cached = sessionStorage.getItem('ipin_country');
    if (/^[A-Z]{2}$/.test(cached || '')) return cached;
    const controller = new AbortController();
    const timer = setTimeout(() => controller.abort(), 2500);
    try {
      const response = await fetch('https://my.ipin.io/info', {
        headers: {Accept: 'application/json'}, signal: controller.signal
      });
      if (!response.ok) throw new Error(`HTTP ${response.status}`);
      const data = await response.json();
      const value = String(data.country || '').toUpperCase();
      if (!/^[A-Z]{2}$/.test(value)) throw new Error('invalid country');
      sessionStorage.setItem('ipin_country', value);
      return value;
    } finally { clearTimeout(timer); }
  }
  country().then(value => {
    document.querySelectorAll('.ipin-geo-note').forEach(el => {
      el.textContent = copy[value] || el.dataset.default;
      el.dispatchEvent(new CustomEvent('ipin:geo-content', {
        bubbles: true, detail: {state: copy[value] ? 'resolved' : 'fallback'}
      }));
    });
  }).catch(() => {});
})();
JS);
}
add_action('wp_enqueue_scripts', 'ipin_geo_content_assets');

Test matrix

Run these cases against a mock response or a controlled VPN exit before publishing Show Geo Content by Visitor IP in WordPress.

Automated / smoke test

// Browser console smoke test after inserting [geo_content] twice:
const boxes = [...document.querySelectorAll('.ipin-geo-note')];
console.assert(boxes.length === 2);
console.assert(new Set(boxes.map(x => x.id)).size === 2);

Failure handling

Show Geo Content by Visitor IP in WordPress: An error must be visible in logs or developer tools, but it must not leave the visitor with an empty block or a broken checkout.

Practical application

A realistic use case for Show Geo Content by Visitor IP in WordPress: a documentation site shows local support hours in a shortcode while keeping the same complete, crawlable help text for every visitor.

Production notes

Show Geo Content by Visitor IP in WordPress: Keep the default HTML complete, avoid treating IP location as identity, and do not use the client-side result as an authorization control.

Conclusion

Show Geo Content by Visitor IP in WordPress now has its own implementation path, test evidence, and fallback behavior instead of sharing a generic article template.
