How to get URL searchParams in form ServerAction?

[deft cargo]

A user can login at this url /sign-in?redirect=%2Fdashboard%3F and I'm trying to read the searchParams in the Server Action, but I can't see how. Is there an event argument or something I can use to see the url the request is coming from?

Doing it like this. Seems like a round about way of doing it, but it works.

  // some ServerAction function
  const _headers = headers();
  const referrer = _headers.get("referer") as string;
  const url = new URL(referrer);
  let redirectPath = url.searchParams.get("redirect");
  if (redirectPath) {
    redirectPath = decodeURIComponent(redirectPath);
  } else {
    redirectPath = "/dashboard";
  }
  return redirect(redirectPath);

I think you could try to read it from the props of the page component or use useSearchParams() hook in client component then pass to the action

How to pass it? In a hidden input in the form?

[empty saddle]

yeah, or use bind

Does bind work with useFormState hook? Then my server action would have 3 arguments? someAction(initialFormState, bindValue, formData);)

[empty saddle]

yes

const [state, formAction] = useFormState(action.bind(null, searchParams), initialState)

then in your action

export async function action(searchParams, prevState, formData) {}
