# Special fields

Control Form Plume with reserved fields: _redirect and _error_redirect for destinations, _route for recipients, and _gotcha for spam honeypot.

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:

```html
<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:

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

See [Success and errors](/docs/forms/success-and-errors) for the dashboard settings, hosted pages, and redirect order.

## Routing

Use `_route` to select a recipient alias you already configured:

```html
<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](/docs/notifications/routing) to create aliases, choose their recipients, and route a form from a select field.

## Honeypot

`_gotcha` is the optional [honeypot field](/docs/spam-protection/honeypot). It must remain empty for real visitors.

Reserved controls are not stored as ordinary submitted answers.
