useStepsForm

useStepsForm hook allows you to split your form under an Ant Design based Steps component and provides you with a few useful functionalities that will help you manage your form.

info

useStepsForm hook is extended from useForm under the hood. This means that you can use all the functionalities of useForm in your useStepsForm.

Basic Usage

We'll do two examples, one for creating and one for editing a post. Let's see how useStepsForm is used in both.

Here is the final result of the form: We will explain the code in following sections.

http://localhost:3000/posts/create
import React from "react";
import { IResourceComponentsProps, HttpError } from "@pankod/refine-core";

import {
Create,
Form,
Input,
Select,
Button,
SaveButton,
useSelect,
useStepsForm,
Steps,
} from "@pankod/refine-antd";

const { Step } = Steps;

const PostCreatePage: React.FC<IResourceComponentsProps> = () => {
const { current, gotoStep, stepsProps, formProps, saveButtonProps } =
useStepsForm<IPost, HttpError, IPost>();

const { selectProps: categorySelectProps } = useSelect<
ICategory,
HttpError
>({
resource: "categories",
});

const formList = [
<>
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
<Form.Item
label="Category"
name={["category", "id"]}
rules={[
{
required: true,
},
]}
>
<Select {...categorySelectProps} />
</Form.Item>
<Form.Item
label="Status"
name="status"
rules={[
{
required: true,
},
]}
>
<Select
options={[
{
label: "Published",
value: "published",
},
{
label: "Draft",
value: "draft",
},
{
label: "Rejected",
value: "rejected",
},
]}
/>
</Form.Item>
</>,
<>
<Form.Item
label="Content"
name="content"
rules={[
{
required: true,
},
]}
>
<Input.TextArea />
</Form.Item>
</>,
];

return (
<Create
footerButtons={
<>
{current > 0 && (
<Button
onClick={() => {
gotoStep(current - 1);
}}
>
Previous
</Button>
)}
{current < formList.length - 1 && (
<Button
onClick={() => {
gotoStep(current + 1);
}}
>
Next
</Button>
)}
{current === formList.length - 1 && (
<SaveButton {...saveButtonProps} />
)}
</>
}
>
<Steps {...stepsProps}>
<Step title="About Post" />
<Step title="Content" />
</Steps>

<Form {...formProps} layout="vertical" style={{ marginTop: 30 }}>
{formList[current]}
</Form>
</Create>
);
};

interface ICategory {
id: number;
title: string;
}

interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: { id: number };
}

For the sake of simplicity, in this example we're going to build a Post "create" form that consists of only a title and a relational category field.

To split your form items under a <Steps> component, first import and use useStepsForm hook in your page:

pages/posts/create.tsx
import React from "react";
import { HttpError } from "@pankod/refine-core";
import { useStepsForm } from "@pankod/refine-antd";

export const PostCreate: React.FC = () => {
const {
current,
gotoStep,
stepsProps,
formProps,
saveButtonProps,
queryResult,
} = useStepsForm<IPost, HttpError, IPost>();

return null;
};

interface ICategory {
id: number;
}

interface IPost {
id: number;
title: string;
status: "published" | "draft" | "rejected";
category: {
id: ICategory["id"];
};
}

useStepsForm is generic over the type form data to help you type check your code.

This hook returns a set of useful values to render steps form. Given current value, you should have a way to render your form items conditionally with this index value. You can use an array to achieve this.

Here, each item of formList corresponds to one step in form:

pages/posts/create.tsx
import React from "react";
import { HttpError } from "@pankod/refine-core";
import {
useStepsForm,
useSelect,
Form,
Input,
Select,
} from "@pankod/refine-antd";

export const PostCreate: React.FC = () => {
const { current, gotoStep, stepsProps, formProps, saveButtonProps } =
useStepsForm<IPost, HttpError, IPost>();

const { selectProps: categorySelectProps } = useSelect<
ICategory,
HttpError
>({
resource: "categories",
});

const formList = [
<>
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
</>,
<>
<Form.Item
label="Category"
name={["category", "id"]}
rules={[
{
required: true,
},
]}
>
<Select {...categorySelectProps} />
</Form.Item>
</>,
];

return null;
};

interface ICategory {
id: number;
title: string;
}

interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: { id: number };
}
tip

Since category is a relational data, we use useSelect to fetch its data.

Refer to useSelect documentation for detailed usage.


You should use stepsProps on <Steps> component, formProps on the <Form> component respectively. And as the last step, you should render the <Steps> component besides the form like this:

pages/posts/create.tsx
import React from "react";
import { HttpError } from "@pankod/refine-core";
import {
useStepsForm,
useSelect,
Form,
Input,
Select,
Create,
Steps,
} from "@pankod/refine-antd";

export const PostCreate: React.FC = () => {
const {
current,
gotoStep,
stepsProps,
formProps,
saveButtonProps,
queryResult,
} = useStepsForm<IPost, HttpError, IPost>();

const { selectProps: categorySelectProps } = useSelect<
ICategory,
HttpError
>({
resource: "categories",
});

const formList = [
<>
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
</>,
<>
<Form.Item
label="Category"
name={["category", "id"]}
rules={[
{
required: true,
},
]}
>
<Select {...categorySelectProps} />
</Form.Item>
</>,
];

return (
<Create saveButtonProps={saveButtonProps}>
<Steps {...stepsProps}>
<Step title="About Post" />
<Step title="Content" />
</Steps>
<Form {...formProps} layout="vertical">
{formList[current]}
</Form>
</Create>
);
};

interface ICategory {
id: number;
title: string;
}

interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: { id: number };
}
Important

Make sure to add as much <Steps.Step> components as the number of steps in the formList array.


To help users navigate between steps in the form, you can use action buttons. Your navigation buttons should use the gotoStep function that was previously returned from the the useStepsForm hook.

pages/posts/create.tsx
import React from "react";
import { HttpError } from "@pankod/refine-core";
import {
useStepsForm,
useSelect,
Form,
Input,
Select,
Create,
Steps,
Button,
SaveButton,
} from "@pankod/refine-antd";

export const PostCreate: React.FC = () => {
const {
current,
gotoStep,
stepsProps,
formProps,
saveButtonProps,
queryResult,
submit,
} = useStepsForm<IPost, HttpError, IPost>();

const { selectProps: categorySelectProps } = useSelect<
ICategory,
HttpError
>({
resource: "categories",
});

const formList = [
<>
<Form.Item
label="Title"
name="title"
rules={[
{
required: true,
},
]}
>
<Input />
</Form.Item>
</>,
<>
<Form.Item
label="Category"
name={["category", "id"]}
rules={[
{
required: true,
},
]}
>
<Select {...categorySelectProps} />
</Form.Item>
</>,
];

return (
<Create
footerButtons={
<>
{current > 0 && (
<Button
onClick={() => {
gotoStep(current - 1);
}}
>
Previous
</Button>
)}
{current < formList.length - 1 && (
<Button
onClick={() => {
gotoStep(current + 1);
}}
>
Next
</Button>
)}
{current === formList.length - 1 && (
<SaveButton
{...saveButtonProps}
style={{ marginRight: 10 }}
onClick={() => submit()}
/>
)}
</>
}
>
<Steps {...stepsProps}>
<Step title="About Post" />
<Step title="Content" />
</Steps>
<Form {...formProps} layout="vertical">
{formList[current]}
</Form>
</Create>
);
};

interface ICategory {
id: number;
title: string;
}

interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: { id: number };
}

Properties

tip

All useForm props also available in useStepsForm. You can find descriptions on useForm docs.

defaultCurrent

Default: 0

Sets the default starting step number. Counting starts from 0.

const stepsForm = useStepsForm({
defaultCurrent: 2,
});

total

Maximum number of steps. <Steps> cannot go beyond this number.

const stepsForm = useStepsForm({
total: 3,
});

isBackValidate

Default: false

When is true, validates a form fields when the user navigates to a previous step.

const stepsForm = useStepsForm({
isBackValidate: true,
});

Return Values

tip

All useForm return values also available in useStepsForm. You can find descriptions on useForm docs.

stepsProps

The props needed by the <Steps> component.

current

Current step, counting from 0.

onChange

Callback function that is trigger when the current step of the form changes. The function takes in one argument, currentStep, which is a number representing the index of the current step.

current

Current step, counting from 0.

gotoStep

Is a function that allows you to programmatically change the current step of a form. It takes in one argument, step, which is a number representing the index of the step you want to navigate to.

submit

A function that can submit the form. It's useful when you want to submit the form manually.

defaultFormValuesLoading

When action is "edit" or "clone", useStepsForm will fetch the data from the API and set it as default values. This prop is true when the data is being fetched.


FAQ

How can I change the form data before submitting it to the API?

You may need to modify the form data before it is sent to the API.

For example, Let's send the values we received from the user in two separate inputs, name and surname, to the API as fullName. We can do this by overriding the submit function.

pages/user/create.tsx
// --
useStepsForm({
submit: (formValues) => {
const data = {
fullName: `${formValues.name} ${formValues.surname}`,
age: formValues.age,
city: formValues.city,
};
onFinish(data as any);
},
});
// --

API Reference

Properties

*: These props have default values in RefineContext and can also be set on <Refine> component. useModalForm will use what is passed to <Refine> as default but a local value will override it.

**: If not explicitly configured, default value of redirect depends on which action used. If action is create, redirects default value is edit (created resources edit page). if action is edit instead, redirects default value is list.
