React Hooks

Payload provides a variety of powerful hooks that can be used within your own React components. With them, you can interface with Payload itself and build just about any type of complex customization you can think of—directly in familiar React code.


The useField hook is used internally within every applicable Payload field component, and it manages sending and receiving a field's state from its parent form.

Outside of internal use, its most common use-case is in custom Field components. When you build a custom React Field component, you'll be responsible for sending and receiving the field's value from the form itself. To do so, import the useField hook as follows:

import { useField } from 'payload/components/forms'
type Props = { path: string }
const CustomTextField: React.FC<Props> = ({ path }) => {
const { value, setValue } = useField<string>({ path })
return <input onChange={e => setValue(} value={value.path} />

The useField hook accepts an args object and sends back information and helpers for you to make use of:

const field = useField<string>({
path: 'fieldPathHere', // required
validate: myValidateFunc, // optional
disableFormData?: false, // if true, the field's data will be ignored
condition?: myConditionHere, // optional, used to skip validation if condition fails
// Here is what `useField` sends back
const {
showError, // whether or not the field should show as errored
errorMessage, // the error message to show, if showError
value, // the current value of the field from the form
formSubmitted, // if the form has been submitted
formProcessing, // if the form is currently processing
setValue, // method to set the field's value in form state
initialValue, // the initial value that the field mounted with
} = field;
// The rest of your component goes here


There are times when a custom field component needs to have access to data from other fields, and you have a few options to do so. The useFormFields hook is a powerful and highly performant way to retrieve a form's field state, as well as to retrieve the dispatchFields method, which can be helpful for setting other fields' form states from anywhere within a form.

Thanks to the awesome package use-context-selector, you can retrieve a specific field's state easily. This is ideal because you can ensure you have an up-to-date field state, and your component will only re-render when that field's state changes.

You can pass a Redux-like selector into the hook, which will ensure that you retrieve only the field that you want. The selector takes an argument with type of [fields: Fields, dispatch: React.Dispatch<Action>]].

import { useFormFields } from 'payload/components/forms';
const MyComponent: React.FC = () => {
// Get only the `amount` field state, and only cause a rerender when that field changes
const amount = useFormFields(([fields, dispatch]) => fields.amount);
// Do the same thing as above, but to the `feePercentage` field
const feePercentage = useFormFields(([fields, dispatch]) => fields.feePercentage);
if (typeof amount?.value !== 'undefined' && typeof feePercentage?.value !== 'undefined') {
return (
<span>The fee is ${(amount.value * feePercentage.value) / 100}</span>


To retrieve more than one field, you can use the useAllFormFields hook. Your component will re-render when any field changes, so use this hook only if you absolutely need to. Unlike the useFormFields hook, this hook does not accept a "selector", and it always returns an array with type of [fields: Fields, dispatch: React.Dispatch<Action>]].

You can do lots of powerful stuff by retrieving the full form state, like using built-in helper functions to reduce field state to values only, or to retrieve sibling data by path.

import { useAllFormFields, reduceFieldsToValues, getSiblingData } from 'payload/components/forms';
const ExampleComponent: React.FC = () => {
// the `fields` const will be equal to all fields' state,
// and the `dispatchFields` method is usable to send field state up to the form
const [fields, dispatchFields] = useAllFormFields();
// Pass in fields, and indicate if you'd like to "unflatten" field data.
// The result below will reflect the data stored in the form at the given time
const formData = reduceFieldsToValues(fields, true);
// Pass in field state and a path,
// and you will be sent all sibling data of the path that you've specified
const siblingData = getSiblingData(fields, 'someFieldName');
return (
// return some JSX here if necessary
Updating other fields' values

If you are building a custom component, then you should use setValue which is returned from the useField hook to programmatically set your field's value. But if you're looking to update another field's value, you can use dispatchFields returned from useFormFields.

You can send the following actions to the dispatchFields function.

ADD_ROWAdds a row of data (useful in array / block field data)
DUPLICATE_ROWDuplicates a row of data (useful in array / block field data)
MODIFY_CONDITIONUpdates a field's conditional logic result (true / false)
MOVE_ROWMoves a row of data (useful in array / block field data)
REMOVERemoves a field from form state
REMOVE_ROWRemoves a row of data from form state (useful in array / block field data)
REPLACE_STATECompletely replaces form state
UPDATEUpdate any property of a specific field's state

The useForm hook can be used to interact with the form itself, and sends back many methods that can be used to reactively fetch form state without causing rerenders within your components each time a field is changed. This is useful if you have action-based callbacks that your components fire, and need to interact with form state based on a user action.

The useForm hook returns an object with the following properties:

fieldsDeprecated. This property cannot be relied on as up-to-date.
submitMethod to trigger the form to submit
dispatchFieldsDispatch actions to the form field state
validateFormTrigger a validation of the form state
createFormDataCreate a multipart/form-data object from the current form's state
disabledBoolean denoting whether or not the form is disabled
getFieldsGets all fields from state
getFieldGets a single field from state by path
getDataReturns the data stored in the form
getSiblingDataReturns form sibling data for the given field path
setModifiedSet the form's modified state
setProcessingSet the form's processing state
setSubmittedSet the form's submitted state
formRefThe ref from the form HTML element
resetMethod to reset the form to its initial state


The useDocumentInfo hook provides lots of information about the document currently being edited, including the following:

collectionIf the doc is a collection, its collection config will be returned
globalIf the doc is a global, its global config will be returned
typeThe type of document being edited (collection or global)
idIf the doc is a collection, its ID will be returned
preferencesKeyThe preferences key to use when interacting with document-level user preferences
versionsVersions of the current doc
unpublishedVersionsUnpublished versions of the current doc
publishedDocThe currently published version of the doc being edited
getVersionsMethod to trigger the retrieval of document versions


import { useDocumentInfo } from 'payload/components/utilities';
const LinkFromCategoryToPosts: React.FC = () => {
const { id } = useDocumentInfo();
// id will be undefined on the create form
if (!id) {
return null;
return (
<a href={`/admin/collections/posts?where[or][0][and][0][category][in][0]=[${id}]`} >
View posts


In any custom component you can get the selected locale with the useLocale hook. Here is a simple example:

import { useLocale } from 'payload/components/utilities';
const Greeting: React.FC = () => {
const locale = useLocale();
const trans = {
en: 'Hello',
es: 'Hola',
return (
<span> { trans[locale] } </span>


Useful to retrieve info about the currently logged in user as well as methods for interacting with it. It sends back an object with the following properties:

userThe currently logged in user
logOutA method to log out the currently logged in user
refreshCookieA method to trigger the silent refreshing of a user's auth token
setTokenSet the token of the user, to be decoded and used to reset the user and token in memory
tokenThe logged in user's token (useful for creating preview links, etc.)
permissionsThe permissions of the current user
import { useAuth } from 'payload/components/utilities';
import { User } from '../payload-types.ts';
const Greeting: React.FC = () => {
const { user } = useConfig<User>();
return (
<span>Hi, {}!</span>


Used to easily fetch the full Payload config.

import { useConfig } from 'payload/components/utilities';
const MyComponent: React.FC = () => {
const config = useConfig();
return (


Sends back how many editing levels "deep" the current component is. Edit depth is relevant while adding new documents / editing documents in modal windows and other cases.

import { useEditDepth } from 'payload/components/utilities';
const MyComponent: React.FC = () => {
const editDepth = useEditDepth();
return (
<span>My component is {editDepth} levels deep</span>


Returns methods to set and get user preferences. More info can be found here.
