react-datepicker with react-final-form

Question

I'm using the react-datepicker inside the react-final-form. I'm using a template with multiple steps https://codesandbox.io/s/km2n35kq3v?file=/index.js. The problem is that I'm not able to integrate the datepicker inside the component. My Code looks like this:

    return (

        <Field name={props.name} parse={() => true}>
            {props => (
                <DatePicker
                    locale="de"
                    placeholderText="Datum eingeben"
                    selected={startDate}
                    dateFormat="P"
                    openToDate={new Date()}
                    minDate={new Date()}
                    disabledKeyboardNavigation
                    name={props.name}
                    value={startDate}
                    onChange={(date) => setStartDate(date)}
                />
            )}
        </Field>

    );

Does anyone knows how I can use it so the data gets passed at the end of the form?

Best regards

I used the wizard form example you sent and added DatePicker similar to yours. Check the wizard example

But basically, I changed your onChange method to actually use react-final-form field props. Now, it uses this.props.input.onChange, which updates the final form state value, and used this.props.input.value to set the selected state (you can then load initial values into final form):

const RenderDatePicker = ({ name, input, input: { value, onChange } }) => {
  return (
    <DatePicker
      locale="de"
      placeholderText="Datum eingeben"
      dateFormat="P"
      selected={value && isValid(value) ? toDate(value) : null} // needs to be checked if it is valid date
      disabledKeyboardNavigation
      name={name}
      onChange={(date) => {
        // On Change, you should use final-form Field Input prop to change the value
        if (isValid(date)) {
          input.onChange(format(new Date(date), "dd-MM-yyyy"));
        } else {
          input.onChange(null);
        }
      }}
    />
  );
};

        <div>
            <label>Date of birth</label>
            <Field
                name="dateOfBirth"
                component={RenderDatePicker}
                validate={required}
            />
            <Error name="dateOfBirth" />
        </div>

Hopefully this helps you.
