useModalForm

useModalForm hook allows you to manage a form within a modal. It provides some useful methods to handle the form modal.

INFORMATION

useModalForm hook is extended from useForm from the @pankod/refine-react-hook-form package. This means that you can use all the features of useForm hook.

Basic Usage​

We'll show three examples, "create", "edit" and "clone". Let's see how useModalForm is used in all.

import React from "react";
import { HttpError, useTable } from "@pankod/refine-core";

import { Modal, PostsTable } from "@components";

const PostList = () => {
  const { tableQueryResult } = useTable<IPost>({
    initialSorter: [
      {
        field: "id",
        order: "desc",
      },
    ],
  });

  const {
    formState: { errors },
    refineCore: { onFinish, formLoading },
    modal: { visible, close, show },
    register,
    handleSubmit,
    saveButtonProps,
  } = useModalForm<IPost, HttpError, IPost>({
    refineCoreProps: { action: "create" },
  });

  const loading = tableQueryResult?.isLoading;

  if (loading) {
    return <div>Loading...</div>;
  }

  return (
