Tango Form Wire

Tango Form Wire is built for developers who prefer to own their form markup without rebuilding the submission pipeline every time.

Add one data-form-relay attribute to an existing same-site HTML form and Tango Form Wire handles the handoff to WordPress. You keep full control of your HTML, CSS and frontend experience while the plugin handles submission processing, email delivery, success and error responses, and stored submissions.

There is no form builder or external form API to configure. The built-in spam protection requires no account; an optional Cloudflare Turnstile widget can be enabled when an additional browser-level check is wanted.

What Tango Form Wire handles

• Connect existing HTML forms with one generated data attribute.
• Create multiple independently configured forms.
• Deliver through WordPress mail, local cPanel SMTP or a custom SMTP server.
• Store valid submissions in WordPress, including failed delivery attempts.
• Build and preview HTML email templates using submission placeholders.
• Show inline loading, success and error responses, or redirect to a WordPress thank-you page.
• Configure sensible sender and Reply-To behaviour.
• Protect submissions with same-site checks, WordPress nonces, a honeypot, payload limits, rate limiting and duplicate protection.
• Optionally require Cloudflare Turnstile verification on selected forms.
• Extend behaviour through developer filters and actions.

You build the form. Tango Form Wire handles the handoff.

Optional Cloudflare Turnstile

The built-in spam protection remains active on every Form without requiring an account. For an additional check, create a Managed widget in Cloudflare Turnstile, open Form Relay > Cloudflare Turnstile, enable the integration, and enter its Site Key and Secret Key. Turnstile can then be enabled independently on each Form.

Each Form offers a Turnstile Location setting. Before the submit button inserts the widget automatically. Manual placement uses an empty element with the data-form-relay-captcha attribute inside the form. The Secret Key can be defined as TANGO_FORM_WIRE_TURNSTILE_SECRET in wp-config.php instead of being stored in WordPress.

When Turnstile is enabled, the visitor’s browser connects to Cloudflare to load the widget and obtain a verification token. Tango Form Wire sends that token to Cloudflare’s Siteverify API before accepting the submission. Tango Form Wire does not send submitted form field contents to Cloudflare.

This service is provided by Cloudflare and is only used after an administrator explicitly configures and enables it:

• Cloudflare Turnstile
• Cloudflare Privacy Policy
• Cloudflare Website and Online Services Terms
