I am trying to use Formik with my react app.
I have react-bootstrap and I am trying to figure out how to style form components with bootstrap styling.
My form is:
// Render Prop
import React from 'react';
import { Link } from 'react-router-dom';
import { Formik, Form, Field, ErrorMessage } from 'formik';
import { Badge, Button, Col, Feedback, FormControl, FormGroup, FormLabel, InputGroup } from 'react-bootstrap';
import * as Yup from 'yup';
const style1 = {
width: '60%',
margin: 'auto'
}
const style2 = {
paddingTop: '2em',
}
const style3 = {
marginRight: '2em'
}
class Basic extends React.Component {
render() {
return (
<Formik
initialValues={{
firstName: '',
lastName: '',
email: '',
role: '',
password: '',
confirmPassword: '',
consent: false
}}
validationSchema={Yup.object().shape({
firstName: Yup.string()
.required('First Name is required'),
lastName: Yup.string()
.required('Last Name is required'),
email: Yup.string()
.email('Email is invalid')
.required('Email is required'),
role: Yup.string()
.required('It will help us get started if we know a little about your background'),
password: Yup.string()
.min(6, 'Password must be at least 6 characters')
.required('Password is required'),
confirmPassword: Yup.string()
.oneOf([Yup.ref('password'), null], 'Passwords must match')
.required('Confirm Password is required')
})}
onSubmit={fields => {
alert('SUCCESS!! :-)\n\n' + JSON.stringify(fields, null, 4))
}}
render={({ errors, status, touched }) => (
<Form style={style1}>
<h1 style={style2}>Get Started</h1>
<div className="form-group">
<label htmlFor="firstName">First Name</label>
<Field name="firstName" type="text" className={'form-control' + (errors.firstName && touched.firstName ? ' is-invalid' : '')} />
<ErrorMessage name="firstName" component="div" className="invalid-feedback" />
</div>
<div className="form-group">
<label htmlFor="lastName">Last Name</label>
<Field name="lastName" type="text" className={'form-control' + (errors.lastName && touched.lastName ? ' is-invalid' : '')} />
<ErrorMessage name="lastName" component="div" className="invalid-feedback" />
</div>
<div className="form-group">
<label htmlFor="email">Email</label>
<Field name="email" type="text" placeholder="Please use your work email address" className={'form-control' + (errors.email && touched.email ? ' is-invalid' : '')} />

</div>
<div className="form-group">

<Field name="role" type="text" placeholder="eg, academic, industry R&D, policy, funder" className={'form-control' + (errors.role && touched.role ? ' is-invalid' : '')} >
</Field>
<ErrorMessage name="role" component="div" className="invalid-feedback" />
</div>
<div className="form-group">
<label htmlFor="password">Password</label>
<Field name="password" type="password" className={'form-control' + (errors.password && touched.password ? ' is-invalid' : '')} />
<ErrorMessage name="password" component="div" className="invalid-feedback" />
</div>
<div className="form-group">
<label htmlFor="confirmPassword">Confirm Password</label>
<Field name="confirmPassword" type="password" className={'form-control' + (errors.confirmPassword && touched.confirmPassword ? ' is-invalid' : '')} />
<ErrorMessage name="confirmPassword" component="div" className="invalid-feedback" />
</div>
<div className="form-group">
<Field component="select" name="color">
<option value="red">Red</option>
<option value="green">Green</option>
<option value="blue">Blue</option>
</Field>
<Field name="consent" label="You must accept the and Privacy Policy" type="checkbox" className={'form-control' + (errors.consent && touched.consent ? ' is-invalid' : '')} />
<ErrorMessage name="consent" component="div" className="invalid-feedback" />
</div>
<div className="form-group">
<Button variant="outline-primary" type="submit" style={style3}>Register</Button>
</div>
</Form>
)}
/>
)
}
}
export default Basic;
When I try to add a react-bootstrap form group to the inside the render method, such as:
<Form.Group controlId="formBasicEmail">
<Form.Label>Email address</Form.Label>
<Form.Control type="email" placeholder="Enter email" />
<Form.Text className="text-muted">
We'll never share your email with anyone else.
</Form.Text>
</Form.Group>
I get an error that says:
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
Check the render method of Formik.
I think this error message is referring to element type to mean 'email' -- but it doesn't make any sense because the formik form i have already has an 'email' type in it and there is not error when I don't try to use react-bootstrap.
Has anyone figured out how to get Formik to work with react-bootstrap?
You're using the wrong Form. Import it from react-bootstrap instead of formik and it should work.

I'm using react-datetime compenent in my react-bootstrap form. Formik with Yup is used for validation.
import React from 'react';
import { Container, Form, Button, Alert, Row, Col, InputGroup } from "react-bootstrap";
import "react-datetime/css/react-datetime.css";
import { Formik} from 'formik';
import * as Icon from 'react-bootstrap-icons';
import * as yup from "yup"
import Datetime from 'react-datetime';
import moment from 'moment';
const validDOB = function( current ){
return current.isBefore(moment());
};
const schema = yup.object().shape({
userId: yup.string().required('Please enter a valid User ID'),
userName: yup.string().required('User\'s Name cannot be empty'),
userDOB: yup.string().required('User\'s Date of Birth cannot be empty'),
});
function AddWorkload(){
return (

Validation for userId and userName is working properly. But I can't get the validation to work for userDOB. I also tried yup.date() but it doesn't work. react-datetime uses moment.js. So, what type to use for the schema and how to get the validation working for that compenent.
Any help would be appreciated.
Thanks
I found my issue. Its because Form.Control.Feedback doesn't correspond to the component Datetime.
So, I removed the Form.Control.Feedback and replaced that with a custom div to display the error message for the Datetime component.
<Form.Group controlId="patientDOB">
<Form.Label>Date of Birth</Form.Label>
<Datetime
inputProps={{
placeholder: 'DD-MM-YYYY',
id: 'userDOB',
name: 'userDOB',
className: formik.errors.userDOB && formik.touched.userDOB ? "form-control is-invalid": "form-control"
}}
closeOnSelect={true}
dateFormat="DD-MM-YYYY"
timeFormat={false}
value={formik.values.userDOB}
isValidDate={validDOB}
onChange={(dateFromValue) => {
formik.setFieldValue('userDOB', moment(dateFromValue).format('DD-MM-YYYY'));
}
}
renderInput={(props) => {
return <input {...props} value={(formik.values.userDOB) ? props.value : ''} />
}}
/>
{formik.errors.userDOB && formik.touched.userDOB ? (
<div className="text-danger" style={{fontSize: '0.875em'}}>{ formik.errors.userDOB }</div>
) : null}
</Form.Group>
First, I made a form validated with formik. After that, my team decided we would style with react-bootstrap. This library has a <Form> object, same as Formik. But it is not validating correctly. It either throws input fields as invalid all the time, thus putting its borders red, or as correct all the time.
I suspect it is a matter of combining libraries that work both with forms and have same-named components. I managed to make it work with original bootstrap library. But I still wanted to know why this happens and if it has some solution.
import React, {useState} from 'react';
import '../FormStyles.css';
import * as yup from "yup";
import { Formik, Form, ErrorMessage, Field } from 'formik';
const TestimonialForm = ({ testimonial = null }) => {
const initialValues = {
name: testimonial?.name || "",
description: testimonial?.description || "",
image: testimonial?.image || ""
};
const schema = yup.object().shape({
name: yup.string().min(4, "Name must be at least 4 characters long.").required("You have to provide a name."),
description: yup.string().required("You have to provide a description."),
image: yup.string()
.matches(
/\.(jpg|png)$/,
"We only support .png or .jpg format files."
)
.required("You have to provide an image.")
});
<Formik
initialValues= {initialValues}
validationSchema = {schema}
>
Here's the form with Formik components
{({}) => (
<div>
<Form className="form-container">
<Field
className="input-field"
type="text"
name="name"
placeholder="Testimonial title"/>
<ErrorMessage name="name" />
<Field
className="input-field"
type="file"
name="image"
placeholder="Testimonial image"/>
<ErrorMessage name="image" />
<button className="submit-btn" type="submit">Send</button>
</Form>
</div>
)}
</Formik>
Here's with react-bootstrap components (I only change the import values.) This are the ones that don't validate well.
{({touched, errors}) => (
<div>
<Form className="form-container" onSubmit={onSubmit}>
<Form.Group controlId="name">
<Form.Control
className="input-field"
type="text"
name="name"
isInvalid={name.touched && errors.name}
placeholder="Testimonial title"/>
<Form.Control.Feedback type="invalid">
{errors.name}
</Form.Control.Feedback>
</Form.Group>
<Form.Group controlId="image">
<Form.Control
className="input-field"
type="file"
name="image"
isInvalid={image.touched && errors.image}
/>
<Form.Control.Feedback type="invalid">
{errors.image}
</Form.Control.Feedback>
</Form.Group>
<button className="submit-btn" type="submit">Send</button>
{message && <div>{message}</div>}
</Form>
</div>
)}
</Formik>
I am trying to validate the password and confirm password field validation. I tried using Redux Form but getting errors.
Is there any passwordsMatch default function, just like checking valid emails?
Is there anyone who knows how to do it?
Following is the code that I have done.
import React, {Component} from 'react'
import { Container, Row, Col, Card, Button } from 'react-bootstrap';
import {Control, LocalForm, Errors} from 'react-redux-form';
const required = (val) => val && val.length;
const maxLength = (len) => (val) => !(val) || (val.length <= len);
const minLength = (len) => (val) => (val) && (val.length >= len);
// for numbers
//const isNumber = (val) => !isNaN(Number(val));
const validEmail = (val) => /^[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}$/i.test(val);
<LocalForm onSubmit={(values) => this.handlerSubmit(values)}>
<Row className="form-group">
<Col>
<Control.text model=".name"
name="name"
className="form-control"
placeholder="Enter your Name"
validators={{
required, minLength: minLength(3), maxLength: maxLength(15)
}}
/>
<Errors
className="text-danger"
model=".name"
show="touched"
messages={{
required: 'Required',
minLength: 'Must be greater than 2 characters',
maxLength: 'Must be 15 characters or less'
}}
/>
</Col>
</Row><br></br>
<Row className="form-group">
<Col>
<Control.text model=".email"
name="email"
className="form-control"
placeholder="Enter a valid email address"
validators={{
required, validEmail
}}

required: 'Required',
validEmail: 'Invalid Email Address'
}}
/>
</Col>
</Row><br></br>
<Row className="form-group">
<Col>
<Control type="password" model=".password"
name="password"
className="form-control"
placeholder="Enter your password"
validators={{
required,
passwordsMatch: (value) => vals.password === vals.conPassword,
}}
/>
<Errors

</Row><br></br>
<Row className="form-group">

/>
</Col>
</Row><br></br>
<Row className="form-group">

</Col>
</Row>

Thank you!</Alert>
<br></br>
<Button type="submit" className="rounded-pill bg-secondary" disabled={!(this.state.agree)}>Submit</Button>
</LocalForm>
I've created custom function from my form using this method
const matchInput = (input, allInputs) => {
return input === allInputs.password ? undefined : 'Passwords do not match';
}
<Field
name="password"
component={InputElement}
label={'Password'}
type={'password'}
required={true}
placeholder="********"/>
<Field
name="cpassword"
component={InputElement}
validate={[matchInput]}
type="password"
label={'Confirm Password'}
required={true}
placeholder="********"/>
Yup Validation Not Working I Also tried Like This import Yup from 'yup' But Still Not Working.., when I create a simple validate Function without YUP it was worked fine. but when I use YUP that time Validation Not Work.
Added Form Component
import React from 'react';
import { useFormik } from 'formik';
import * as Yup from 'yup';
const initialValues = {
name : "",
surname : "",
address : ""
}
const validateSchema = Yup.object({
name: Yup.string().required('This Field is Required'),
surname: Yup.string().required('This Field is Required'),
address: Yup.string().required('This Field is Required')
});
const onSubmit = values =>{
console.log('FormData->',values);
}
function Form() {
const formik = useFormik({
initialValues ,
onSubmit ,
validateSchema
})
return (
<div className="container x col-md-4 col-md-offset-4" >
<form onSubmit={formik.handleSubmit} >
<div className="form-group">
<input autoComplete="off" onBlur={formik.handleBlur} onChange={formik.handleChange}
value={formik.values.name} name="name" className="name form-control-lg" placeholder="Enter A Name" />
<small>
{formik.touched.name && formik.errors.name ? <div className="error"> {formik.errors.name} </div> : null}
</small>
</div>
<div className="form-group">
<input autoComplete="off" onBlur={formik.handleBlur} onChange={formik.handleChange}
value={formik.values.surname} name="surname" className="surname form-control-lg" placeholder="Enter A Surname" />
<small> { formik.touched.surname && formik.errors.surname ? <div className="error"> {formik.errors.surname} </div> : null} </small>
</div>
<div className="form-group">
<input autoComplete="off" onBlur={formik.handleBlur} onChange={formik.handleChange} value={formik.values.address}
name="address" className="address form-control-lg" placeholder="Enter A Address" />
<small> {formik.touched.address && formik.errors.address ? <div className="error"> {formik.errors.address} </div> : null} </small>
</div>
<button className="btn btn-danger" >Submit</button>
</form>
</div>
)
}
export default Form;
The valid option here is validationSchema not validateSchema. Just set the right one:
const validationSchema = Yup.object({
// ...
});
useFormik({
// ...
validationSchema
})
To use formik and yup, first you have you do npm install yup and npm install formik. if your yarn user then do yarn add formik and yarn add yup.
after that follow this code.
import {Formik} from 'formik';
import * as yup from 'yup';
//functional component am using
export const Auth = () => {
const initialFormValue ={
email: '',password: '',};
const SignInSchema = yup.object().shape({
email: yup.string().email('Invalid Email').required('Email is Required'),
password: yup.string().min(5, 'Too Short').required('Password is Required'),
})
<Formik initialValues={initialFormValue} validationSchema={SignInSchema}
onSubmit={values => console.log(values)}>
{({values, errors, touched, handleChange, handleBlur,
handleSubmit,isSubmitting,
isValid}) => (
<>
<input name='email' type='email' handleChange={handleChange} value=
{values.email} onBlur={handleBlur} label='Email' />
{errors.email && touched.email ? (<Error>{errors.email}</Error>): null}
<input name='password' type='password' handleChange={handleChange} value=
{values.password} onBlur={handleBlur} label='Password' />
{errors.password && touched.password ? (<Error>{errors.password}</Error>):
null}
<button onClick={handleSubmit} type="submit">Send</button>
</>
) }
</Formik>
)}
its not necessary for you to define initial value outside you can do inside formik too <Formik initialValues={email: '', password: ''}> </Formik>
i hope this will help you thank you.
I am trying to figure out how to send form data form a Formik form to a Firebase database in my react app.
I have a form as follows:

I have a database in firebase (cloud firestore) with a collection called Registrations that has fields named the same as each of these form fields.
I have spent the day following tutorials that seem to be made for react before Formik. There's not much point to showing all the things I've tried and failed at for the day - they're clearly not written with Formik in mind. I can't find a way to write the onSubmit so that Formik can give the data to Firebase.
Has anyone found a current tutorial or know how to do this?
I've used Formik and Firebase in this Open-Source React project. Maybe this is what you're looking for :)
