Handling Multiple Step Form Submission in React with Validation and State Management Issues
I've been struggling with this for a few days now and could really use some help. I'm working on a multi-step form in React using Formik for form management and Yup for validation. The form has three steps: user info, address, and payment details. However, I'm working with issues where the state does not continue correctly between steps, especially after validation fails. For example, when submitting the first step, if validation fails, the values are lost, and I have to re-enter them. Here's a simplified version of my implementation: ```javascript import React from 'react'; import { Formik } from 'formik'; import * as Yup from 'yup'; const validationSchema = Yup.object({ name: Yup.string().required('Name is required'), email: Yup.string().email('Invalid email').required('Email is required'), }); const MyForm = () => { const handleSubmit = (values, { setStep }) => { console.log(values); // Logic to move to next step or handle submission }; return ( <Formik initialValues={{ name: '', email: '' }} validationSchema={validationSchema} onSubmit={handleSubmit} > {({ handleChange, handleBlur, handleSubmit, values, errors }) => ( <form onSubmit={handleSubmit}> <input type="text" name="name" onChange={handleChange} onBlur={handleBlur} value={values.name} /> {errors.name && <div>{errors.name}</div>} <input type="email" name="email" onChange={handleChange} onBlur={handleBlur} value={values.email} /> {errors.email && <div>{errors.email}</div>} <button type="submit">Next</button> </form> )} </Formik> ); }; export default MyForm; ``` I'm using React 17, Formik 2.2, and Yup 0.32. The scenario arises mainly when I hit the submit button without filling the form correctly. The form resets, causing frustration as I have to re-enter all the data. I’ve tried using `setFieldTouched` to preserve the data, but it didn't resolve the scenario. Is there a better way to manage state across multiple steps and ensure data persistence during validation? Any suggestions would be greatly appreciated. What's the best practice here? For context: I'm using Javascript on Windows. What's the best practice here?
