I am working with playload cms & trying to create a doc in collection with a file, following this payload documentation article

Collection config code

import type { CollectionConfig } from 'payload'
export const DemoCollection: CollectionConfig = {
  slug: 'demoCollection',
  fields: [
    {
      type: 'text',
      name: 'title',
      label: 'Title',
    },
    { type: 'upload', name: 'image', label: 'Image', relationTo: 'media' },
  ],
}

Upload Page attached

'use client'
const FormSchema = z.object({
  title: z.string().min(2, {
    message: 'Title must be at least 2 characters.',
  }),
  image: z.instanceof(FileList),

I am using payload v3, this is also working with v2. There is upload property for the collection, it is not a field. Just submit a post request with a FormData. Here is an example:

> collections/media.ts

export const Media: CollectionConfig = {
  slug: 'media',
  labels: {
    plural: 'Media',
    singular: 'Media',
  },
  access: {
    read: () => true,
    create: () => true,
  },
  fields: [
    {
      name: 'someField',
      type: 'text',
    },
  ],
  upload: true,
}

And the request itself:

const fd = new FormData()
fd.append('file', YOUR_FILE_HERE as File)
fd.append('someField', 'SOME_VALUE')

const res = await fetch('/api/media', {
      method: 'POST',
      credentials: 'include',
      body: fd,
})

const resJson = await res.json()

// Then you can update the collection file field with the new file id
const newFileId = resJson.doc.id

// Make a payload.update request to update the demoCollection with file id
...

Hope this will help.
