# Feedback form: HTML, React and Next.js code

> A short feedback form with a 1 to 5 rating and an optional comment, for product pages, docs and in-app widgets.

## Copy the code

Every version below is generated from the same field definition. Replace `frm_xxxxxxxxxxxxxxxx` with your form id, or enter it in the **Form ID** box and the code updates.

**HTML** (`feedback.html`)

```html
<form action="https://ikiform.com/f/frm_xxxxxxxxxxxxxxxx" method="post">
  <label for="rating">How useful was this?</label>
  <input id="rating" name="rating" type="number" min="1" max="5" step="1" required />
  <label for="comment">What would make it better?</label>
  <textarea id="comment" name="comment" rows="4" maxlength="4000"></textarea>
  <label for="email">Email, if you'd like a reply</label>
  <input id="email" name="email" type="email" autocomplete="email" />
  <input name="_gotcha" type="text" tabindex="-1" autocomplete="off" hidden />
  <button>Send feedback</button>
</form>
```

**React** (`FeedbackForm.tsx`)

```tsx
import { submit } from "@ikiform/sdk";
import { type FormEvent, useState } from "react";

const FORM_ID = "frm_xxxxxxxxxxxxxxxx";

type Status = "idle" | "sending" | "sent" | "error";

export function FeedbackForm() {
  const [status, setStatus] = useState<Status>("idle");
  const [errors, setErrors] = useState<Record<string, string[]>>({});
  const [message, setMessage] = useState("");

  async function onSubmit(event: FormEvent<HTMLFormElement>) {
    event.preventDefault();
    setStatus("sending");
    setErrors({});
    const result = await submit(FORM_ID, new FormData(event.currentTarget));
    if (result.ok) return setStatus("sent");
    setErrors(result.error.fields ?? {});
    setMessage(result.error.message);
    setStatus("error");
  }

  if (status === "sent") return <p>Thanks for the feedback.</p>;

  return (
    <form onSubmit={onSubmit}>
      <label htmlFor="rating">How useful was this?</label>
      <input id="rating" name="rating" type="number" min={1} max={5} step={1} required />
      {errors.rating ? <p>{errors.rating[0]}</p> : null}
      <label htmlFor="comment">What would make it better?</label>
      <textarea id="comment" name="comment" rows={4} maxLength={4000} />
      {errors.comment ? <p>{errors.comment[0]}</p> : null}
      <label htmlFor="email">Email, if you'd like a reply</label>
      <input id="email" name="email" type="email" autoComplete="email" />
      {errors.email ? <p>{errors.email[0]}</p> : null}
      <input name="_gotcha" type="text" tabIndex={-1} autoComplete="off" hidden />
      {status === "error" && !Object.keys(errors).length ? <p role="alert">{message}</p> : null}
      <button disabled={status === "sending"}>{status === "sending" ? "Sending" : "Send feedback"}</button>
    </form>
  );
}
```

**JavaScript** (`feedback.js`)

```js
const form = document.querySelector('form[action="https://ikiform.com/f/frm_xxxxxxxxxxxxxxxx"]');
const status = document.createElement("p");
status.setAttribute("role", "alert");
form.append(status);

const labels = {
  rating: "How useful was this?",
  comment: "What would make it better?",
  email: "Email, if you'd like a reply",
};

form.addEventListener("submit", async (event) => {
  event.preventDefault();
  const button = form.querySelector("button");
  button.disabled = true;
  status.textContent = "";
  try {
    const response = await fetch(form.action, {
      method: "POST",
      headers: { Accept: "application/json" },
      body: new FormData(form),
    });
    const result = await response.json();
    if (result.ok) {
      form.replaceWith("Thanks for the feedback.");
      return;
    }
    const fields = Object.entries(result.error.fields ?? {});
    status.textContent = fields.length
      ? fields.map(([id, messages]) => `${labels[id] ?? id}: ${messages[0]}`).join(" ")
      : result.error.message;
  } catch {
    status.textContent = "Couldn't reach the server. Try again.";
  }
  button.disabled = false;
});
```

- **HTML** needs no JavaScript. After a successful post the browser is redirected to the form's redirect URL, or to Ikiform's hosted thank-you page.
- **React** uses the SDK: `npm install @ikiform/sdk`. Field errors from the server appear under each field.
- **JavaScript** enhances the HTML form with `fetch`, so the visitor stays on the page.
- The hidden `_gotcha` input is the honeypot. Leave it empty and hidden.

> If you set the form's spam check to **Ikiform**, the HTML form keeps working with no change and the server action skips the check because it sends a secret key. The React and JavaScript versions must get a token before each submit: call `challenge(FORM_ID)` from `@ikiform/sdk` and pass it to `submit` as `turnstileToken`, or add it to the `fetch` body as `cf-turnstile-response`. Without it the post is refused with `403 challenge_required`. See [the Next.js guide](https://ikiform.com/docs/guides/nextjs.md#client-human-check) and [Spam protection](https://ikiform.com/docs/spam.md#human-check).

## The fields

Paste this definition on the form's **Fields** tab in the dashboard. Ikiform then checks every post against it on the server, refuses bad data with `422 validation_failed`, refuses any field that isn't listed, and stores typed values.

| Field id | Type | Required | Accepts |
| --- | --- | --- | --- |
| `rating` | `rating` | Yes | 1 to 5 |
| `comment` | `textarea` | No | Up to 4,000 characters |
| `email` | `email` | No | One valid address |

`Field definition`:

```json
{
  "version": 1,
  "title": "Feedback",
  "fields": [
    {
      "id": "rating",
      "type": "rating",
      "label": "How useful was this?",
      "required": true,
      "validation": {
        "max": 5
      }
    },
    {
      "id": "comment",
      "type": "textarea",
      "label": "What would make it better?",
      "rows": 4,
      "validation": {
        "max_length": 4000
      }
    },
    {
      "id": "email",
      "type": "email",
      "label": "Email, if you'd like a reply"
    }
  ],
  "settings": {
    "submit_label": "Send feedback",
    "success_message": "Thanks for the feedback."
  }
}
```

## Next.js server action

To keep the form working without JavaScript in a Next.js app, post from a server action with a secret key. Create the key under **API keys** with the `submissions:write` scope and keep it out of the browser.

`.env.local`:

```bash
IKIFORM_SECRET_KEY=ik_sk_your_secret_key
```

`app/feedback/actions.ts`:

```ts
"use server";

export interface FeedbackFormState {
  ok: boolean;
  message: string;
  fields?: Record<string, string[]>;
  values?: Record<string, string[]>;
}

export async function sendFeedbackForm(_previous: FeedbackFormState, formData: FormData): Promise<FeedbackFormState> {
  const body = new URLSearchParams();
  for (const [name, value] of formData) {
    if (typeof value === "string" && !name.startsWith("$ACTION")) body.append(name, value);
  }
  const response = await fetch("https://ikiform.com/f/frm_xxxxxxxxxxxxxxxx", {
    method: "POST",
    headers: {
      Accept: "application/json",
      Authorization: `Bearer ${process.env.IKIFORM_SECRET_KEY}`,
    },
    body,
  });
  const result = await response.json();
  if (result.ok) return { ok: true, message: "Thanks for the feedback." };
  const values = Object.fromEntries([...new Set(body.keys())].map((name) => [name, body.getAll(name)]));
  return { ok: false, message: result.error.message, fields: result.error.fields, values };
}
```

`app/feedback/form.tsx`:

```tsx
"use client";

import { useActionState } from "react";
import { type FeedbackFormState, sendFeedbackForm } from "./actions";

const initial: FeedbackFormState = { ok: false, message: "" };

export function FeedbackForm() {
  const [state, action, pending] = useActionState(sendFeedbackForm, initial);

  if (state.ok) return <p>{state.message}</p>;

  return (
    <form action={action}>
      <label htmlFor="rating">How useful was this?</label>
      <input id="rating" name="rating" type="number" min={1} max={5} step={1} required defaultValue={state.values?.rating?.[0]} />
      {state.fields?.rating ? <p>{state.fields.rating[0]}</p> : null}
      <label htmlFor="comment">What would make it better?</label>
      <textarea id="comment" name="comment" rows={4} maxLength={4000} defaultValue={state.values?.comment?.[0]} />
      {state.fields?.comment ? <p>{state.fields.comment[0]}</p> : null}
      <label htmlFor="email">Email, if you'd like a reply</label>
      <input id="email" name="email" type="email" autoComplete="email" defaultValue={state.values?.email?.[0]} />
      {state.fields?.email ? <p>{state.fields.email[0]}</p> : null}
      <input name="_gotcha" type="text" tabIndex={-1} autoComplete="off" hidden />
      {state.message && !state.fields ? <p role="alert">{state.message}</p> : null}
      <button disabled={pending}>{pending ? "Sending" : "Send feedback"}</button>
    </form>
  );
}
```

> A server action posts from your server's IP, so the per-visitor rate limit counts every visitor together. Use the Relaxed or Custom [rate limit](https://ikiform.com/docs/rate-limits.md) for forms you send through a server.

## Set it up

1. Create a form in the [dashboard](https://ikiform.com/dashboard) and copy its id.
2. Paste the field definition on the **Fields** tab.
3. Add your site under **Allowed domains**, plus `localhost` while you develop.
4. Set the rate limit to **Standard, 5 a minute per visitor** if visitors post from the browser. Feedback is one post per visit. Standard leaves room for a second thought. With the server action, every post comes from your server's IP, so choose Relaxed or Custom instead.
5. Paste the code, send a test and check it arrives in the dashboard.

## The rating field

A `rating` accepts a whole number from 1 to `max`, which is 5 here and can be 2 to 10. It is stored as a number, so averages and charts need no parsing. `0`, `6` and `3.5` are refused.

## Knowing which page it came from

Every submission records the visitor's user agent, origin, referrer and country alongside the fields. Webhooks include them under `data.meta`, so you don't need hidden fields for the page or the browser.

| Metadata | Example |
| --- | --- |
| `referrer` | `https://example.com/docs/install` |
| `origin` | `https://example.com` |
| `user_agent` | `Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)` |
| `country` | `GB` |

## As a small widget

A feedback form often lives in a corner of every page. Post it with `fetch` or the SDK so the visitor stays on the page, and add each domain it appears on under **Allowed domains**. Keep the email optional: people give more honest feedback when they don't have to identify themselves.

> Send low ratings somewhere the team will see them today, such as a Slack or Discord channel, and all ratings to a sheet or database for trends.

## Where to send it

Every submission can go to a signed [webhook](https://ikiform.com/docs/webhooks.md). These guides cover the tools that suit this form, with the relay code:

- [Send form submissions to Slack](https://ikiform.com/blog/form-submissions-to-slack.md)
- [Send form submissions to Discord](https://ikiform.com/blog/form-submissions-to-discord.md)
- [Send form submissions to a Notion database](https://ikiform.com/blog/form-submissions-to-notion.md)
- [Send form submissions to Google Sheets](https://ikiform.com/blog/form-submissions-to-google-sheets.md)
- [Create Linear or GitHub issues from form submissions](https://ikiform.com/blog/form-submissions-to-linear-and-github-issues.md)

## Questions

### Can I use a 0 to 10 scale?

Not with a rating field, which starts at 1 and goes up to 10 at most. For 0 to 10, use a number field with min 0, max 10 and integer true, as the survey form does.

### How do I know which page the feedback is about?

Ikiform records the referrer and origin with every submission and includes them in webhooks, so you don't need a hidden page field.

### Is feedback anonymous?

The fields are only what the visitor types, and email is optional here. Ikiform still records the user agent, origin, referrer and country with each submission.
