Domain Search for WHMCS

Domain Search for WHMCS is a lightweight WordPress plugin that adds a polished domain search form to your site and hands the visitor off to your existing WHMCS billing portal to complete registration.

It is purpose-built for hosting providers, domain resellers, ICANN registrars, and white-label hosting brands who already use WHMCS as their billing platform.

Tl;dr

• Install, activate, paste [domain_search_for_whmcs] on any page.
• No JavaScript on the front-end. No external requests. No tracking.
• Create unlimited branded shortcodes pointing at different WHMCS installs.
• Modern admin dashboard with built-in support center.
• Translation-ready, multisite-friendly, GDPR-friendly.

Why this plugin

Most WHMCS integrations are heavy or hard-coded. This one is the opposite: a single, dependency-free shortcode that drops into any layout. It does one thing and does it cleanly.

• No external API calls — submits directly to your own WHMCS install.
• No JavaScript on the public site (admin-only JS for the dashboard tabs).
• Works with classic themes, block themes, and every major page builder.
• Visitor queries never touch a third-party server.

Key features

Drop-in shortcode — [domain_search_for_whmcs] works in posts, pages, widgets, FSE template parts, page-builder shortcode blocks, or via do_shortcode() in PHP.

Unlimited custom shortcodes — create branded forms each pointing at a different WHMCS install with its own placeholder. Reference them as [domain_search_for_whmcs id="sc_xxxxx"].

Modern admin dashboard — tabbed UI, click-to-copy shortcodes, an “At a Glance” overview (custom shortcode count, active host, HTTPS status), and a built-in Support tab.

Built for speed — one ~1.7 KB CSS file. No JavaScript, no jQuery, no Ajax, no remote assets, no tracking pixels.

Theme-agnostic styling — six stable, well-named CSS classes you can target from any theme or page builder.

Developer extensibility — five filter hooks let plugins and themes change behavior without forking. See Developer Filters below.

Secure by default — nonce verification, capability checks, sanitized I/O, properly escaped output.

Translation-ready — every string wrapped in the domain-search-for-whmcs text domain.
