Reserved form fields: configuration guide

Most named fields become submission data. Reserved fields begin with an underscore and tell Form Plume how to handle the request.

Redirect

Use _redirect only when one request needs a different success destination from the form's saved setting:

<input type="hidden" name="_redirect" value="https://example.com/thank-you">

The destination must satisfy the form's redirect safety rules.

Use _error_redirect when the same form needs a separate failure destination:

<input type="hidden" name="_error_redirect" value="https://example.com/form-error">

See Success and errors for the dashboard settings, hosted pages, and redirect order.

Use _route to select a recipient alias you already configured:

<input type="hidden" name="_route" value="sales">

A visitor cannot create a new recipient by changing this value. Unknown aliases are ignored or rejected according to the routing settings.

See Email routing to create aliases, choose their recipients, and route a form from a select field.

_gotcha is the optional honeypot field. It must remain empty for real visitors.

Reserved controls are not stored as ordinary submitted answers.
