PhoneField

A PhoneField is an input field that merchants can type into optimized for phone numbers with a country code base auto-formatting. The country code is required for the initial render of the field but it can be overriden later by the user either by selecting a country in the country selection dropdown or by manually editing the country phone code directly in the text field.

Basic PhoneField

import {
  reactExtension,
  PhoneField,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return (
    <PhoneField
      label="Phone"
      value="1 (555) 555-5555"
    />
  );
}

import {extension, PhoneField} from '@shopify/ui-extensions/checkout';

export default extension('purchase.checkout.block.render', (root) => {
  const phoneField = root.createComponent(PhoneField, {
    label: 'Phone',
    value: '1 (555) 555-5555',
  });

  root.appendChild(phoneField);
});

PhoneFieldProps

accessibilityDescription

A detailed description for screen readers.

accessory

Any content to render at the end of the text field. Commonly used to display an icon that opens a tooltip providing more information about the field.

autocomplete

A hint as to the intended content of the field. When set to `true`, this property indicates that the field should support autofill, but you do not have any more semantic information on the intended contents. When set to `false`, you are indicating that this field contains sensitive information, or contents that are never saved, like one-time codes. Alternatively, you can provide an `Autocomplete` object, which describes the specific data you would like to be entered into this field during autofill.

disabled

Whether the field can be modified.

error

Indicate an error to the user. The field will be given a specific stylistic treatment to communicate problems that have to be resolved immediately.

icon

An icon to render at the start or end of the field. It will render at the start by default.

id

A unique identifier for the field. When no `id` is set, a globally unique value will be used instead.

label

Content to use as the field label. This value is also used as the placeholder when the field is empty.

maxLength

Specifies the maximum number of characters allowed.

name

An identifier for the field that is unique within the nearest containing `Form` component.

onBlur

Callback when focus is removed.

onChange

Callback when the buyer has **finished editing** a field or pressed the country dropdown. Unlike `onChange` callbacks you may be familiar with from Polaris or other React component libraries, this callback is **not** run on every change to the input. Phone fields are “partially controlled” components, which means that while the buyer edits the field, its state is controlled by the component. Once the buyer has signalled that they have finished editing the field (typically, by blurring the field), `onChange` is called if the input actually changed from the most recent `value` property. At that point, you are expected to store this “committed value” in state, and reflect it in the phone field’s `value` property. This state management model is important given how UI Extensions are rendered. UI Extension components run on a separate thread from the UI, so they can’t respond to input synchronously. A pattern popularized by [controlled React components](https://reactjs.org/docs/forms.html#controlled-components) is to have the component be the source of truth for the input `value`, and update the `value` on every user input. The delay in responding to events from a UI extension is only a few milliseconds, but attempting to strictly store state with this delay can cause issues if a user types quickly, or if the buyer is using a lower-powered device. Having the UI thread take ownership for “in progress” input, and only synchronizing when the user is finished with a field, avoids this risk. It can still sometimes be useful to be notified when the user makes any input in the field. If you need this capability, you can use the `onInput` prop. However, never use that property to create tightly controlled state for the `value`. This callback is called with the current formatted value of the field. If the value of a field is the same as the current `value` prop provided to the field, the `onChange` callback will not be run.

onFocus

Callback when input is focused.

onInput

Callback when the user makes any changes in the field including selecting a country in the dropdown. As noted in the documentation for `onChange`, you must not use this to update `state` — use the `onChange` callback for that purpose. Use the `onInput` prop when you need to do something as soon as the buyer makes a change, like clearing validation errors that apply to the field as soon as the user begins making the necessary adjustments. This callback is called with the current formatted value.

readonly

Whether the field is read-only.

required

Whether the field needs a value. This requirement adds semantic value to the field, but it will not cause an error to appear automatically. If you want to present an error when this field is empty, you can do so with the `error` prop.

value

The current value for the field. If omitted, the field will be empty. You should update this value in response to the `onChange` callback.

Autocomplete

A descriptor for selecting the data a field would like to receive during autocomplete. This attribute is modeled off of a limited set of the autocomplete values supported in browsers.

field

The type of data that should be inserted into a field supporting autocomplete.

group

The contact information “group” the autocomplete data should be sourced from.
