# next-safe-action Form Integration

## Options

| Approach | When to Use |
|---|---|
| `useAction` + native form | Simple forms, no complex validation UI |
| `useHookFormAction` (RHF adapter) | Complex forms with field-level errors, validation on change/blur |
| `useHookFormOptimisticAction` | RHF forms with optimistic UI updates |

## Quick Start — Native Form

```tsx
"use client";

import { useAction } from "next-safe-action/hooks";
import { submitContact } from "@/app/actions";

export function ContactForm() {
  const { execute, result, isPending } = useAction(submitContact);

  return (
    <form
      onSubmit={(e) => {
        e.preventDefault();
        const fd = new FormData(e.currentTarget);
        execute({
          name: fd.get("name") as string,
          email: fd.get("email") as string,
          message: fd.get("message") as string,
        });
      }}
    >
      <input name="name" required />
      <input name="email" type="email" required />
      <textarea name="message" required />

      {result.validationErrors && (
        <p>{result.validationErrors.email?._errors?.[0]}</p>
      )}
      {result.serverError && <p>{result.serverError}</p>}
      {result.data && <p>Message sent!</p>}

      <button type="submit" disabled={isPending}>
        {isPending ? "Sending..." : "Send"}
      </button>
    </form>
  );
}
```

## Quick Start — React Hook Form Adapter

```tsx
"use client";

import { useHookFormAction } from "@next-safe-action/adapter-react-hook-form/hooks";
import { zodResolver } from "@hookform/resolvers/zod";
import { z } from "zod";
import { submitContact } from "@/app/actions";

const schema = z.object({
  name: z.string().min(1, "Name is required"),
  email: z.string().email("Invalid email"),
  message: z.string().min(10, "Message must be at least 10 characters"),
});

export function ContactForm() {
  const { form, handleSubmitWithAction, action } = useHookFormAction(
    submitContact,
    zodResolver(schema),
    {
      actionProps: {
        onSuccess: () => toast.success("Message sent!"),
      },
    }
  );

  return (
    <form onSubmit={handleSubmitWithAction}>
      <input {...form.register("name")} />
      {form.formState.errors.name && <p>{form.formState.errors.name.message}</p>}

      <input {...form.register("email")} />
      {form.formState.errors.email && <p>{form.formState.errors.email.message}</p>}

      <textarea {...form.register("message")} />
      {form.formState.errors.message && <p>{form.formState.errors.message.message}</p>}

      {action.result.serverError && <p>{action.result.serverError}</p>}

      <button type="submit" disabled={action.isPending}>
        {action.isPending ? "Sending..." : "Send"}
      </button>
    </form>
  );
}
```
