The Upload field allows for the selection of a Document from a collection supporting Uploads, and
formats the selection as a thumbnail in the Admin panel.
Important:
To use this field, you need to have a Collection configured to allow Uploads. For more
information, [click here](/docs/upload/overview) to read about how to enable Uploads on a
collection by collection basis.
**Example uses:**
- To provide a `Page` with a featured image
- To allow for a `Product` to deliver a downloadable asset like PDF or MP3
- To give a layout building block the ability to feature a background image
### Config
| Option | Description |
|----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **`name`** \* | To be used as the property name when stored and retrieved from the database. [More](/docs/fields/overview#field-names) |
| **`*relationTo`** \* | Provide a single collection `slug` to allow this field to accept a relation to. Note: the related collection must be configured to support Uploads. |
| **`filterOptions`** | A query to filter which options appear in the UI and validate against. [More](#filtering-upload-options). |
| **`maxDepth`** | Sets a number limit on iterations of related documents to populate when queried. [Depth](/docs/getting-started/concepts#depth) |
| **`label`** | Text used as a field label in the Admin panel or an object with keys for each language. |
| **`unique`** | Enforce that each entry in the Collection has a unique value for this field. |
| **`validate`** | Provide a custom validation function that will be executed on both the Admin panel and the backend. [More](/docs/fields/overview#validation) |
| **`index`** | Build an [index](/docs/database/overview) for this field to produce faster queries. Set this field to `true` if your users will perform queries on this field's data often. |
| **`saveToJWT`** | If this field is top-level and nested in a config supporting [Authentication](/docs/authentication/config), include its data in the user JWT. |
| **`hooks`** | Provide field-based hooks to control logic for this field. [More](/docs/fields/overview#field-level-hooks) |
| **`access`** | Provide field-based access control to denote what users can see and do with this field's data. [More](/docs/fields/overview#field-level-access-control) |
| **`hidden`** | Restrict this field's visibility from all APIs entirely. Will still be saved to the database, but will not appear in any API or the Admin panel. |
| **`defaultValue`** | Provide data to be used for this field's default value. [More](/docs/fields/overview#default-values) |
| **`localized`** | Enable localization for this field. Requires [localization to be enabled](/docs/configuration/localization) in the Base config. |
| **`required`** | Require this field to have a value. |
| **`admin`** | Admin-specific configuration. See the [default field admin config](/docs/fields/overview#admin-config) for more details. |
| **`custom`** | Extension point for adding custom data (e.g. for plugins) |
_\* An asterisk denotes that a property is required._
### Example
`collections/ExampleCollection.ts`
```ts
import { CollectionConfig } from 'payload/types'
export const ExampleCollection: CollectionConfig = {
slug: 'example-collection',
fields: [
{
name: 'backgroundImage', // required
type: 'upload', // required
relationTo: 'media', // required
required: true,
},
],
}
```
### Filtering upload options
Options can be dynamically limited by supplying a [query constraint](/docs/queries/overview), which will be used both
for validating input and filtering available uploads in the UI.
The `filterOptions` property can either be a `Where` query, or a function returning `true` to not filter, `false` to
prevent all, or a `Where` query. When using a function, it will be
called with an argument object with the following properties:
| Property | Description |
|---------------|--------------------------------------------------------------------------------------------------------------|
| `relationTo` | The collection `slug` to filter against, limited to this field's `relationTo` property |
| `data` | An object containing the full collection or global document currently being edited |
| `siblingData` | An object containing document data that is scoped to only fields within the same parent of this field |
| `id` | The `id` of the current document being edited. `id` is `undefined` during the `create` operation |
| `user` | An object containing the currently authenticated user |
### Example
```ts
const uploadField = {
name: 'image',
type: 'upload',
relationTo: 'media',
filterOptions: {
mimeType: { contains: 'image' },
},
}
```
You can learn more about writing queries [here](/docs/queries/overview).
Note:
When an upload field has both filterOptions and a custom{' '}
validate function, the api will not validate filterOptions{' '}
unless you call the default upload field validation function imported from{' '}
payload/fields/validations in your validate function.
