Form is used to collect, validate, and submit the user input, usually contains various form items including checkbox, radio, input, select, and etc.

When to use

When you need to create a instance or collect information.
When you need to validate fields in certain rules.

Form Component

You can align the controls of a form using the layout prop：

horizontal：to horizontally align the labels and controls of the fields. (Default)
vertical：to vertically align the labels and controls of the fields.
inline：to render form fields in one line.

Form Item Component

A form consists of one or more form fields whose type includes input, textarea, checkbox, radio, select, tag, and more. A form field is defined using <Form.Item />.

<Form.Item {...props}>{children}</Form.Item>

API

Form

more example rc-form。

Property	Description	Type	Default Value
form	Decorated by `Form.create()` will be automatically set `this.props.form` property	object	n/a
hideRequiredMark	Hide required mark of all form items	Boolean	false
labelAlign	Label text align	'left' \| 'right'	'right'
labelCol	(Added in 3.14.0. Previous version can only set on FormItem.) 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>`	object
layout	Define form layout	'horizontal'\|'vertical'\|'inline'	'horizontal'
onSubmit	Defines a function will be called if form data validation is successful.	Function(e:Event)
wrapperCol	(Added in 3.14.0. Previous version can only set on FormItem.) The layout for input controls, same as `labelCol`	object
colon	change default props colon value of Form.Item	boolean	true

Form.create(options)

How to use：

class CustomizedForm extends React.Component {}

CustomizedForm = Form.create({})(CustomizedForm);

The following options are available:

Property	Description	Type
mapPropsToFields	Convert props to field value(e.g. reading the values from Redux store). And you must mark returned fields with `Form.createFormField`. Please note that the form fields will become controlled components. Properties like errors will not be automatically mapped and need to be manually passed in.	(props) => ({ [fieldName]: FormField { value } })
name	Set the id prefix of fields under form	-
validateMessages	Default validate message. And its format is similar with newMessages's returned value	Object { [nested.path]: String }
onFieldsChange	Specify a function that will be called when the fields (including errors) of a `Form.Item` gets changed. Usage example: saving the field's value to Redux store.	Function(props, changedFields, allFields)
onValuesChange	A handler while value of any field is changed	(props, changedValues, allValues) => void

If you want to get ref after Form.create, you can use wrappedComponentRef provided by rc-form, details can be viewed here.

class CustomizedForm extends React.Component { ... }

// use wrappedComponentRef
const EnhancedForm =  Form.create()(CustomizedForm);
<EnhancedForm wrappedComponentRef={(form) => this.form = form} />
this.form // => The instance of CustomizedForm

If the form has been decorated by Form.create then it has this.props.form property. this.props.form provides some APIs as follows:

Note: Before using getFieldsValue getFieldValue setFieldsValue and so on, please make sure that corresponding field had been registered with getFieldDecorator.

Method	Description	Type
getFieldDecorator	Two-way binding for form, please read below for details.
getFieldError	Get the error of a field.	Function(name)
getFieldsError	Get the specified fields' error. If you don't specify a parameter, you will get all fields' error.	Function([names: string[]])
getFieldsValue	Get the specified fields' values. If you don't specify a parameter, you will get all fields' values.	Function([fieldNames: string[]])
getFieldValue	Get the value of a field.	Function(fieldName: string)
isFieldsTouched	Check whether any of fields is touched by `getFieldDecorator`'s `options.trigger` event	(names?: string[]) => boolean
isFieldTouched	Check whether a field is touched by `getFieldDecorator`'s `options.trigger` event	(name: string) => boolean
isFieldValidating	Check if the specified field is being validated.	Function(name)
resetFields	Reset the specified fields' value(to `initialValue`) and status. If you don't specify a parameter, all the fields will be reset.	Function([names: string[]])
setFields	Set value and error state of fields. Code Sample	({ [fieldName]: {value: any, errors: [Error] } }) => void
setFieldsValue	Set the value of a field. (Note: please don't use it in `componentWillReceiveProps`, otherwise, it will cause an endless loop, reason)	({ [fieldName]: value }) => void
validateFields	Validate the specified fields and get theirs values and errors. If you don't specify the parameter of fieldNames, you will validate all fields.	( [fieldNames: string[]], [options: object], callback(errors, values) ) => void
validateFieldsAndScroll	This function is similar to `validateFields`, but after validation, if the target field is not in visible area of form, form will be automatically scrolled to the target field area.	same as `validateFields`

validateFields/validateFieldsAndScroll

const {
  form: { validateFields },
} = this.props;
validateFields((errors, values) => {
  // ...
});
validateFields(['field1', 'field2'], (errors, values) => {
  // ...
});
validateFields(['field1', 'field2'], options, (errors, values) => {
  // ...
});

Method	Description	Type	Default
options.first	If `true`, every field will stop validation at first failed rule	boolean	false
options.firstFields	Those fields will stop validation at first failed rule	String[]	[]
options.force	Should validate validated field again when `validateTrigger` is been triggered again	boolean	false
options.scroll	Config scroll behavior of `validateFieldsAndScroll`, more: dom-scroll-into-view's config	Object	{}

Callback arguments example of validateFields

errors:

{
  "username": {
    "errors": [
      {
        "message": "Please input your username!",
        "field": "username"
      }
    ]
  },
  "password": {
    "errors": [
      {
        "message": "Please input your Password!",
        "field": "password"
      }
    ]
  }
}

values:

{
  "username": "username",
  "password": "password",
}

Form.createFormField

To mark the returned fields data in mapPropsToFields, demo.

this.props.form.getFieldDecorator(id, options)

After wrapped by getFieldDecorator, 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:

You shouldn't use onChange to collect data, but you still can listen to onChange(and so on) events.
You cannot set value of form control via value defaultValue prop, and you should set default value with initialValue in getFieldDecorator instead.
You shouldn't call setState manually, please use this.props.form.setFieldsValue to change value programmatically.

Special attention

If you use react@<15.3.0, then, you can't use getFieldDecorator in stateless component: facebook/react#6534

getFieldDecorator(id, options) parameters

Property	Description	Type	Default Value
id	The unique identifier is required. support nested fields format.	string
options.getValueFromEvent	Specify how to get value from event or other onChange arguments	function(..args)	reference
options.getValueProps	Get the component props according to field value.	function(value): any	reference
options.initialValue	You can specify initial value, type, optional value of children node. (Note: Because `Form` will test equality with `===` internally, we recommend to use variable as `initialValue`, instead of literal)		n/a
options.normalize	Normalize value to form component, a select-all example	function(value, prevValue, allValues): any	-
options.preserve	Keep the field even if field removed	boolean	-
options.rules	Includes validation rules. Please refer to "Validation Rules" part for details.	object[]	n/a
options.trigger	When to collect the value of children node	string	'onChange'
options.validateFirst	Whether stop validate on first rule of error for this field.	boolean	false
options.validateTrigger	When to validate the value of children node.	string\|string[]	'onChange'
options.valuePropName	Props of children node, for example, the prop of Switch is 'checked'.	string	'value'

More option at rc-form option。

Form.Item

Note: if Form.Item has multiple children that had been decorated by getFieldDecorator, help and required and validateStatus can't be generated automatically.

Property	Description	Type	Default Value	Version
