Reset Form in Formik Not Working? Find Out Why and How to Fix It

Are you having trouble with Formik's reset form functionality? You're not alone! Many developers have encountered this issue, and it can be frustrating, especially when you're working on a critical project. In this article, we'll explore the possible reasons why your Formik reset form might not be working and provide easy-to-implement solutions.

Understanding Formik's Reset Form Functionality

Before we dive into the troubleshooting process, let's take a look at how Formik's reset form functionality works. Formik is a popular React library for building forms, and it provides a resetForm method that allows you to reset the form's fields to their initial values. This method is useful when you want to clear the form fields after submission or when the user navigates away from the form.

Common Reasons for Formik Reset Form Not Working

Now that we've covered the basics, let's explore some common reasons why your Formik reset form might not be working:

• Incorrect Usage of resetForm Method: One of the most common reasons for Formik's reset form not working is incorrect usage of the resetForm method. Make sure you're calling the method correctly and passing the required arguments.
• Missing initialValues: If you don't provide initialValues for your form fields, Formik won't be able to reset them to their initial values. Ensure that you've defined initialValues for all your form fields.
• ** Mutations or Side Effects**: If you have any mutations or side effects in your form that modify the form's state, it can prevent Formik's reset form functionality from working as expected.

Easy Solutions to Fix Formik Reset Form Not Working Issue

Now that we've identified the common reasons for Formik's reset form not working, let's explore some easy solutions to fix the issue:

Solution 1: Verify Correct Usage of resetForm Method

First, make sure you're calling the resetForm method correctly. Here's an example of how to use the resetForm method:

import { Formik, Form } from 'formik';

const MyForm = () => {
  const formik = new Formik({
    initialValues: {
      name: '',
      email: '',
    },
    onSubmit: (values, { resetForm }) => {
      console.log(values);
      resetForm(); // Call resetForm method here
    },
  });

  return (
    

      
      
      Submit
    
  );
};

Solution 2: Provide Initial Values for All Form Fields

Ensure that you've defined initialValues for all your form fields. If you don't provide initialValues, Formik won't be able to reset the form fields to their initial values.

import { Formik, Form } from 'formik';

const MyForm = () => {
  const formik = new Formik({
    initialValues: {
      name: '',
      email: '',
      phone: '', // Provide initial value for phone field
    },
    onSubmit: (values, { resetForm }) => {
      console.log(values);
      resetForm();
    },
  });

  return (
    

      
      
       // Add phone field
      Submit
    
  );
};

Solution 3: Avoid Mutations or Side Effects

If you have any mutations or side effects in your form that modify the form's state, it can prevent Formik's reset form functionality from working as expected. Try to avoid using mutations or side effects, and instead, use Formik's built-in methods to update the form's state.

import { Formik, Form } from 'formik';

const MyForm = () => {
  const formik = new Formik({
    initialValues: {
      name: '',
      email: '',
    },
    onSubmit: (values, { resetForm, setFieldValue }) => {
      console.log(values);
      setFieldValue('name', 'John Doe'); // Use setFieldValue to update form field
      resetForm();
    },
  });

  return (
    

      
      
      Submit
    
  );
};
