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

info

useModalForm hook is extended from useForm from the @refinedev/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.

create

http://localhost:3000

import React from 'react'
import { HttpError, useTable } from '@refinedev/core'
import { useModalForm } from '@refinedev/react-hook-form'

import { Modal, PostsTable } from '@components'

const PostList = () => {
  const { tableQueryResult } = useTable<IPost>({
    sorters: {
      initial: [
        {
          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 (
    <div>
      <Modal isOpen={visible} onClose={close}>
        <form className="form" onSubmit={handleSubmit(onFinish)}>
          <div className="form-group">
            <label>Title: </label>
            <input
              {...register('title', {
                required: 'This field is required',
              })}
            />

          </button>
        </form>
      </Modal>
      <button onClick={() => show()}>Create Post</button>
      <table>
        <thead>
          <tr>

          </tr>
        </thead>
        <tbody>
          {tableQueryResult.data?.data.map((post) => (
            <tr key={post.id}>
              <td>{post.id}</td>
              <td>{post.title}</td>
              <td>{post.status}</td>

edit

caution

refine doesn't automatically add a <EditButton/> to the each record in <PostList> which opens edit form in <Modal> when clicked.

So, we have to put the <EditButton/> on our list. In that way, <Edit> form in <Modal> can fetch data by the record id.

<td>
  <button onClick={() => show(post.id)}>Edit</button>
</td>

caution

Don't forget to pass the record "id" to show to fetch the record data. This is necessary for both "edit" and "clone" forms.

clone

caution

refine doesn't automatically add a <CloneButton/> to the each record in <PostList> which opens edit form in <Modal> when clicked.

So, we have to put the <CloneButton/> on our list. In that way, <Clone> form in <Modal> can fetch data by the record id.

<td>
  <button onClick={() => show(post.id)}>clone</button>
</td>

caution

Don't forget to pass the record "id" to show to fetch the record data. This is necessary for both "edit" and "clone" forms.
