React Redux Form - Password and Confirm password validation


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"

                        validators={{
                            required, minLength: minLength(3), maxLength: maxLength(15)
                        }}

Solution

  • 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="********"/>
