# up.Params.fromFields(fields)

**This feature is experimental**. Please [share](https://github.com/unpoly/unpoly/discussions) your experiences so we know what to keep or change.

Constructs a new [`up.Params`](https://unpoly.com/api/up.Params.md) instance from one or more [HTML form fields](https://www.w3schools.com/html/html_form_elements.asp).

The constructed [`up.Params`](https://unpoly.com/api/up.Params.md) will include exactly those form values that would be included for the given fields in a regular form submission. If a given field wouldn't submit a value (like an unchecked `<input type="checkbox">`), nothing will be added.

See [`up.Params.fromForm()`](https://unpoly.com/api/up.Params.fromForm.md) for more details and examples.
