### validateMessages

Form provides [default verification error messages](https://github.com/react-component/field-form/blob/master/src/utils/messages.ts). You can modify the template by configuring `validateMessages` property. A common usage is to configure localization:

```jsx
const validateMessages = {
  required: "'${name}' is required!",
  // ...
};

<Form validateMessages={validateMessages} />;
```

Besides, [ConfigProvider](/components/config-provider/) also provides a global configuration scheme that allows for uniform configuration error notification templates:

```jsx
const validateMessages = {
  required: "'${name}' is Required!",
  // ...
};

<ConfigProvider form={{ validateMessages }}>
  <Form />
</ConfigProvider>;
```

## Form.Item

Form field component for data bidirectional binding, validation, layout, and so on.

| Property | Description | Type | Default | Version |
| --- | --- | --- | --- | --- |
| colon | Used with `label`, whether to display `:` after label text. | boolean | true |  |
| dependencies | Set the dependency field. See [below](#dependencies) | [NamePath](#NamePath)\[] | - |  |
| extra | The extra prompt message. It is similar to help. Usage example: to display error message and prompt message at the same time | ReactNode | - |  |
| getValueFromEvent | Specify how to get value from event or other onChange arguments | (..args: any\[]) => any | - |  |
| getValueProps | Additional props with sub component | (value: any) => any | - | 4.2.0 |
| hasFeedback | Used with `validateStatus`, this option specifies the validation status icon. Recommended to be used only with `Input` | boolean | false |  |
| help | The prompt message. If not provided, the prompt message will be generated by the validation rule. | ReactNode | - |  |
| hidden | Whether to hide Form.Item (still collect and validate value) | boolean | false | 4.4.0 |
| htmlFor | Set sub label `htmlFor` | string | - |  |
| initialValue | Config sub default value. Form `initialValues` get higher priority when conflict | string | - | 4.2.0 |
| label | Label text | ReactNode | - |  |
| labelAlign | The text align of label | `left` \| `right` | `right` |  |
| labelCol | The layout of label. You can set `span` `offset` to something like `{span: 3, offset: 12}` or `sm: {span: 3, offset: 12}` same as with `<Col>`. You can set `labelCol` on Form which will not affect nest Item. If both exists, use Item first | [object](/components/grid/#Col) | - |  |
| messageVariables | The default validate field info | Record&lt;string, string> | - | 4.7.0 |
| name | Field name, support array | [NamePath](#NamePath) | - |  |
| normalize | Normalize value from component value before passing to Form instance. Do not support async | (value, prevValue, prevValues) => any | - |  |
| noStyle | No style for `true`, used as a pure field control | boolean | false |  |
| preserve | Keep field value even when field removed | boolean | true | 4.4.0 |
| required | Display required style. It will be generated by the validation rule | boolean | false |  |
| rules | Rules for field validation. Click [here](#components-form-demo-basic) to see an example | [Rule](#Rule)\[] | - |  |
| shouldUpdate | Custom field update logic. See [below](#shouldUpdate) | boolean \| (prevValue, curValue) => boolean | false |  |
| tooltip | Config tooltip info | ReactNode \| [TooltipProps & { icon: ReactNode }](/components/tooltip#API) | - | 4.7.0 |
| trigger | When to collect the value of children node. Click [here](#components-form-demo-customized-form-controls) to see an example | string | `onChange` |  |
| validateFirst | Whether stop validate on first rule of error for this field. Will parallel validate when `parallel` cofigured | boolean \| `parallel` | false | `parallel`: 4.5.0 |
| validateStatus | The validation status. If not provided, it will be generated by validation rule. options: `success` `warning` `error` `validating` | string | - |  |
| validateTrigger | When to validate the value of children node | string \| string\[] | `onChange` |  |
| valuePropName | Props of children node, for example, the prop of Switch is 'checked'. This prop is an encapsulation of `getValueProps`, which will be invalid after customizing `getValueProps` | string | `value` |  |
| wrapperCol | The layout for input controls, same as `labelCol`. You can set `wrapperCol` on Form which will not affect nest Item. If both exists, use Item first | [object](/components/grid/#Col) | - |  |

After wrapped by `Form.Item` with `name` property, `value`(or other property defined by `valuePropName`) `onChange`(or other property defined by `trigger`) props will be added to form controls, the flow of form data will be handled by Form which will cause:

1. You shouldn't use `onChange` on each form control to **collect data**(use `onValuesChange` of Form), but you can still listen to `onChange`.
2. You cannot set value for each form control via `value` or `defaultValue` prop, you should set default value with `initialValues` of Form. Note that `initialValues` cannot be updated by `setState` dynamically, you should use `setFieldsValue` in that situation.
3. You shouldn't call `setState` manually, please use `form.setFieldsValue` to change value programmatically.

### dependencies

Used when there are dependencies between fields. If a field has the `dependencies` prop, this field will automatically trigger updates and validations when upstream is updated. A common scenario is a user registration form with "password" and "confirm password" fields. The "Confirm Password" validation depends on the "Password" field. After setting `dependencies`, the "Password" field update will re-trigger the validation of "Check Password". You can refer [examples](#components-form-demo-register).

`dependencies` shouldn't be used together with `shouldUpdate`, since it may result in conflicting update logic.

`dependencies` supports `Form.Item` with render props children since `4.5.0`.

### shouldUpdate

Form updates only the modified field-related components for performance optimization purposes by incremental update. In most cases, you only need to write code or do validation with the [`dependencies`](#dependencies) property. In some specific cases, such as when a new field option appears with a field value changed, or you just want to keep some area updating by form update, you can modify the update logic of Form.Item via the `shouldUpdate`.

When `shouldUpdate` is `true`, any Form update will cause the Form.Item to be re-rendered. This is very helpful for custom rendering some areas:

```jsx
<Form.Item shouldUpdate>
  {() => {
    return <pre>{JSON.stringify(form.getFieldsValue(), null, 2)}</pre>;
  }}
</Form.Item>
```

You can ref [example](#components-form-demo-horizontal-login) to see detail.

When `shouldUpdate` is a function, it will be called by form values update. Providing original values and current value to compare. This is very helpful for rendering additional fields based on values:

```jsx
<Form.Item shouldUpdate={(prevValues, curValues) => prevValues.additional !== curValues.additional}>
  {() => {
    return (
      <Form.Item name="other">
        <Input />
      </Form.Item>
    );
  }}
</Form.Item>
```

You can ref [example](#components-form-demo-control-hooks) to see detail.

### messageVariables

You can modify the default verification information of Form.Item through `messageVariables`.

```jsx
<Form>
  <Form.Item messageVariables={{ another: 'good' }} label="user">
    <Input />
  </Form.Item>
  <Form.Item messageVariables={{ label: 'good' }} label={<span>user</span>}>
    <Input />
  </Form.Item>
</Form>
```

## Form.List

Provides array management for fields.

| Property | Description | Type | Default | Version |
| --- | --- | --- | --- | --- |
| children | Render function | (fields: Field\[], operation: { add, remove, move }, meta: { errors }) => React.ReactNode | - |  |
| initialValue | Config sub default value. Form `initialValues` get higher priority when conflict | any\[] | - | 4.9.0 |
| name | Field name, support array | [NamePath](#NamePath) | - |  |
| rules | Validate rules, only support customize validator. Should work with [ErrorList](#Form.ErrorList) | { validator, message }\[] | - | 4.7.0 |

```tsx
<Form.List>
  {fields => (
    <div>
      {fields.map(field => (
        <Form.Item {...field}>
          <Input />
        </Form.Item>
      ))}
    </div>
  )}
</Form.List>
```

Note: You should not configure Form.Item `initialValue` under Form.List. It always should be configured by Form.List `initialValue` or Form `initialValues`.

## operation

Some operator functions in render form of Form.List.

| Property | Description | Type | Default | Version |
| --- | --- | --- | --- | --- |
| add | add form item | (defaultValue?: any, insertIndex?: number) => void | insertIndex | 4.6.0 |
| move | move form item | (from: number, to: number) => void | - |  |
| remove | remove form item | (index: number \| number\[]) => void | number\[] | 4.5.0 |

## Form.ErrorList

New in 4.7.0. Show error messages, should only work with `rules` of Form.List. See [example](#components-form-demo-dynamic-form-item).

| Property | Description | Type         | Default |
| -------- | ----------- | ------------ | ------- |
| errors   | Error list  | ReactNode\[] | -       |

## Form.Provider

Provide linkage between forms. If a sub form with `name` prop update, it will auto trigger Provider related events. See [example](#components-form-demo-form-context).

| Property | Description | Type | Default |
| --- | --- | --- | --- |
| onFormChange | Triggered when a sub form field updates | function(formName: string, info: { changedFields, forms }) | - |
| onFormFinish | Triggered when a sub form submits | function(formName: string, info: { values, forms }) | - |

```jsx
<Form.Provider
  onFormFinish={name => {
    if (name === 'form1') {
      // Do something...
    }
  }}
>
  <Form name="form1">...</Form>
  <Form name="form2">...</Form>
</Form.Provider>
```

| validateFields | Validate fields | (nameList?: [NamePath](#NamePath)\[]) => Promise |  |

#### validateFields return sample

```jsx
validateFields()
  .then(values => {
    /*
  values:
    {
      username: 'username',
      password: 'password',
    }
  */
  })
  .catch(errorInfo => {
    /*
    errorInfo:
      {
        values: {
          username: 'username',
          password: 'password',
        },
        errorFields: [
          { name: ['password'], errors: ['Please input your Password!'] },
        ],
        outOfDate: false,
      }
    */
  });
```

## Hooks

### Form.useForm

`type Form.useForm = (): [FormInstance]`

Create Form instance to maintain data store.

### Form.useFormInstance

`type Form.useFormInstance = (): FormInstance`

Added in `4.20.0`. Get current context form instance to avoid pass as props between components:

```tsx
const Sub = () => {
  const form = Form.useFormInstance();

  return <Button onClick={() => form.setFieldsValue({})} />;
};

export default () => {
  const [form] = Form.useForm();

  return (
    <Form form={form}>
      <Sub />
    </Form>
  );
};
```

### Form.useWatch

`type Form.useWatch = (namePath: NamePath, formInstance?: FormInstance): Value`

Added in `4.20.0`. Watch the value of a field. You can use this to interactive with other hooks like `useSWR` to reduce develop cost:

```tsx
const Demo = () => {
  const [form] = Form.useForm();
  const userName = Form.useWatch('username', form);

  const { data: options } = useSWR(`/api/user/${userName}`, fetcher);

  return (
    <Form form={form}>
      <Form.Item name="username">
        <AutoComplete options={options} />
      </Form.Item>
    </Form>
  );
};
```

### Form.Item.useStatus

`type Form.useFormItemStatus = (): { status: ValidateStatus | undefined }`

Added in `4.22.0`. Could be used to get validate status of Form.Item. If this hook is not used under Form.Item, `status` would be `undefined`:

```tsx
const CustomInput = ({ value, onChange }) => {
  const { status } = Form.Item.useStatus();
  return <input value={value} onChange={onChange} className={`custom-input-${status}`} />;
};

export default () => (
  <Form>
    <Form.Item name="username">
      <CustomInput />
    </Form.Item>
  </Form>
);
```

#### Difference between other data fetching method

Form only update the Field which changed to avoid full refresh perf issue. Thus you can not get real time value with `getFieldsValue` in render. And `useWatch` will rerender current component to sync with latest value. You can also use Field renderProps to get better performance if only want to do conditional render. If component no need care field value change, you can use `onValuesChange` to give to parent component to avoid current one rerender.

### Interface

#### NamePath

`string | number | (string | number)[]`

#### FieldData

| Name       | Description              | Type                     |
| ---------- | ------------------------ | ------------------------ |
| errors     | Error messages           | string\[]                |
| name       | Field name path          | [NamePath](#NamePath)\[] |
| touched    | Whether is operated      | boolean                  |
| validating | Whether is in validating | boolean                  |
| value      | Field value              | any                      |

#### Rule

Rule supports a config object, or a function returning config object:

```tsx
type Rule = RuleConfig | ((form: FormInstance) => RuleConfig);
```

| Name | Description | Type | Version |
| --- | --- | --- | --- |
| defaultField | Validate rule for all array elements, valid when `type` is `array` | [rule](#Rule) |  |
| enum | Match enum value. You need to set `type` to `enum` to enable this | any\[] |  |
| fields | Validate rule for child elements, valid when `type` is `array` or `object` | Record&lt;string, [rule](#Rule)> |  |
| len | Length of string, number, array | number |  |
| max | `type` required: max length of `string`, `number`, `array` | number |  |
| message | Error message. Will auto generate by [template](#validateMessages) if not provided | string |  |
| min | `type` required: min length of `string`, `number`, `array` | number |  |
| pattern | Regex pattern | RegExp |  |
| required | Required field | boolean |  |
| transform | Transform value to the rule before validation | (value) => any |  |
| type | Normally `string` \|`number` \|`boolean` \|`url` \| `email`. More type to ref [here](https://github.com/yiminghe/async-validator#type) | string |  |
| validateTrigger | Set validate trigger event. Must be the sub set of `validateTrigger` in Form.Item | string \| string\[] |  |
| validator | Customize validation rule. Accept Promise as return. See [example](#components-form-demo-register) | ([rule](#Rule), value) => Promise |  |
| warningOnly | Warning only. Not block form submit | boolean | 4.17.0 |
| whitespace | Failed if only has whitespace, only work with `type: 'string'` rule | boolean |  |

## Migrate to v4

If you are a user of v3, you can ref [migrate doc](/components/form/v3)。

<style>
.code-box-demo .ant-form:not(.ant-form-inline):not(.ant-form-vertical) {
  max-width: 600px;
}
.markdown.api-container table td:nth-of-type(4) {
  white-space: nowrap;
  word-wrap: break-word;
}
</style>

## FAQ

### Custom validator not working

It may be caused by your `validator` if it has some errors that prevents `callback` to be called. You can use `async` instead or use `try...catch` to catch the error:

```jsx
validator: async (rule, value) => {
  throw new Error('Something wrong!');
}

// or

validator(rule, value, callback) => {
  try {
    throw new Error('Something wrong!');
  } catch (err) {
    callback(err);
  }
}
```

### How does `name` fill value when it's an array?

`name` will fill value by array order. When there exists number in it and no related field in form store, it will auto convert field to array. If you want to keep it as object, use string like: `['1', 'name']`.

### Why is there a form warning when used in Modal?

> Warning: Instance created by `useForm` is not connect to any Form element. Forget to pass `form` prop?

Before Modal opens, children elements do not exist in the view. You can set `forceRender` on Modal to pre-render its children. Click [here](https://codesandbox.io/s/antd-reproduction-template-ibu5c) to view an example.

### Why is component `defaultValue` not working when inside Form.Item?

Components inside Form.Item with name property will turn into controlled mode, which makes `defaultValue` not work anymore. Please try `initialValues` of Form to set default value.

### Why can not call `ref` of Form at first time?

`ref` only receives the mounted instance. please ref React official doc: <https://reactjs.org/docs/refs-and-the-dom.html#accessing-refs>

### Why will `resetFields` re-mount component?

`resetFields` will re-mount component under Field to clean up customize component side effects (like async data, cached state, etc.). It's by design.

### Difference between Form initialValues and Item initialValue?

In most case, we always recommend to use Form `initialValues`. Use Item `initialValue` only with dynamic field usage. Priority follows the rules:

1. Form `initialValues` is the first priority
2. Field `initialValue` is secondary \*. Does not work when multiple Item with same `name` setting the `initialValue`

### Why does `onFieldsChange` trigger three times on change when field sets `rules`?

Validating is also part of the value updating. It pass follow steps:

1. Trigger value change
2. Rule validating
3. Rule validated

In each `onFieldsChange`, you will get `false` > `true` > `false` with `isFieldValidating`.

### Why doesn't Form.List support `label` and need ErrorList to show errors?

Form.List use renderProps which mean internal structure is flexible. Thus `label` and `error` can not have best place. If you want to use antd `label`, you can wrap with Form.Item instead.

### Why can't Form.Item `dependencies` work on Form.List field?

Your name path should also contain Form.List `name`:

```tsx
<Form.List name="users">
  {fields =>
    fields.map(field => (
      <React.Fragment key={field.key}>
        <Form.Item name={[field.name, 'name']} {...someRest1} />
        <Form.Item name={[field.name, 'age']} {...someRest1} />
      </React.Fragment>
    ))
  }
</Form.List>
```

dependencies should be `['users', 0, 'name']`

### Why doesn't `normalize` support async?

React can not get correct interaction of controlled component with async value update. When user trigger `onChange`, component will do no response since `value` update is async. If you want to trigger value update async, you should use customize component to handle value state internal and pass sync value control to Form instead.

<style>
  .site-form-item-icon {
    color: rgba(0, 0, 0, 0.25);
  }
  [data-theme="dark"] .site-form-item-icon {
    color: rgba(255,255,255,.3);
  }
</style>

`scrollToFirstError` and `scrollToField` deps on `id` attribute passed to form control, please make sure that it hasn't been ignored in your custom form control. Check [codesandbox](https://codesandbox.io/s/antd-reproduction-template-forked-25nul?file=/index.js) for solution.

### `setFieldsValue` do not trigger `onFieldsChange` or `onValuesChange`?

It's by design. Only user interactive can trigger the change event. This design is aim to avoid call `setFieldsValue` in change event which may makes loop calling.
