Accessing props in onSubmit method of react-dropzone-uploader

Question

I am using react-dropzone-uploader to upload files. Everything works OK; except that I want the parent Component to be updated after clicking on submit button. What should I do?

This is the part of code I use:

export default () => {

  const handleSubmit = (files, allFiles) => {
    console.log('uploads files:', files, this)
    // There is no access to props here.
  }

  return (
    <Dropzone
      getUploadParams={getUploadParams}
      onChangeStatus={handleChangeStatus}
      onSubmit={handleSubmit}
      accept="image/*,.pdf,.doc,.docx"
    />
  )
}

Answer 1

As it is a functional component you don't need this and you get props from

export default (props) => {

  const handleSubmit = (files, allFiles) => {
    console.log('uploads files:', files)
    // Get set state function from props
    props.setFiles(files)
  }

  return (
    <Dropzone
      getUploadParams={getUploadParams}
      onChangeStatus={handleChangeStatus}
      onSubmit={handleSubmit}
      accept="image/*,.pdf,.doc,.docx"
    />
  )
}

And in the parent, you can call this component as

...
const [files, setFiles] = useState(null)
...
return (
  <div>
  <div>Drop files</div>
  <CustomDropzone setFiles={setFiles} />
  </div>
)
