I use react-hook-form and would like to display message to the user after submitting form. I know how to do that with alert, but would like to have that message as a paragraph. After submitting fields should be again empty.
Here is my Form component:
import React from "react";
import { useForm } from "react-hook-form";
const Form = ({ title }) => {
const { register, handleSubmit, errors } = useForm();
const onSubmit = (data, e) => {
e.preventDefault();
console.log(data);
alert(`thank you ${data.name} for your message`);
};
return (
<div className="formContainer">
<Title title="Lets stay in touch" />
<div className="form">
<form onSubmit={handleSubmit(onSubmit)}>
<div className="form__row">
<input
className={`inputForm ${errors.name ? "inputFormError" : ""}`}
name="name"
type="text"
placeholder="name"
ref={register({ required: true })}
/>
<input
className={`inputForm ${
errors.surname ? "inputFormError" : ""
}`}
name="surname"
type="text"
placeholder="surname"
ref={register({ required: true })}
/>
</div>
<div>
<textarea
className={`inputForm areaForm ${
errors.message ? "inputFormError" : ""
}`}
name="message"
placeholder="Your message"
ref={register({ required: true })}
></textarea>
</div>
<div>
<button className="form__formButton" type="submit">
Send
</button>
</div>
</form>
</div>
</div>
);
};
export default Form;
Pretty simple with just a useState to show the message and reset API from hookForm to reset the form :
import React from "react";
import { useForm } from "react-hook-form";
const Form = ({ title }) => {
const [message, setMessage] = useState('');
const { register, handleSubmit, errors, reset } = useForm();
const onSubmit = (data, e) => {
e.preventDefault();
console.log(data);
setMessage(`thank you ${data.name} for your message`);
reset();
};
return (
<div className="formContainer">
<Title title="Lets stay in touch" />
<div className="form">
{message}
<form onSubmit={handleSubmit(onSubmit)}>
<div className="form__row">
<input
className={`inputForm ${errors.name ? "inputFormError" : ""}`}
name="name"
type="text"
placeholder="name"
ref={register({ required: true })}
/>
<input
className={`inputForm ${
errors.surname ? "inputFormError" : ""
}`}
name="surname"
type="text"
placeholder="surname"
ref={register({ required: true })}
/>
</div>
<div>
<textarea
className={`inputForm areaForm ${
errors.message ? "inputFormError" : ""
}`}
name="message"
placeholder="Your message"
ref={register({ required: true })}
></textarea>
</div>
<div>
<button className="form__formButton" type="submit">
Send
</button>
</div>
</form>
</div>
</div>
);
};
export default Form;

This is what I'm stuck with for last couple of hours. I have tried default values from react hook form. I kinda getting the user input on the console but for firebase it's showing error. It is working with the normal input system

const [createUserWithEmailAndPassword,loading] =
useCreateUserWithEmailAndPassword(auth);
const navigate = useNavigate();
const [user] = useAuthState(auth);
useEffect(() => {
if (user) {
navigate("/home");
}
}, [navigate, user]);
const {
register,
formState: { errors },
handleSubmit,
} = useForm();
const onSubmit = (data) => {

So after submitting, I can see the data on console but can't send them to firebase.
I am trying to create validations for my react-hook-form but when I go try to display the errors on the front end I receive this error.
×
TypeError: Cannot read properties of undefined (reading 'name')
It seems like everything is working until I try to display it with the following code
{errors.name && errors.name.message}
import emailjs from "emailjs-com";
import { useForm } from "react-hook-form";
const Contact = () => {
const [successMessage, setSuccessMessage] = useState("");
const { register, handleSubmit, errors } = useForm();
const serviceID = "s_ID";
const templateID = "t_ID";
const userID = "user_12345";
const onSubmit = (data, r) => {
sendEmail(
serviceID,
templateID,
{
name: data.name,
email: data.email,
subject: data.subject,
description: data.description,
},
userID
)
r.target.reset();
}
const sendEmail = (serviceID, templateID, variables, userID) => {
emailjs.send(serviceID, templateID, variables, userID)
.then(() => {
setSuccessMessage("Form sent successfully! I'll contact you as soon as possible");
}).catch(err => console.error(`Something went wrong ${err}`));
};
return (

Your code helped me debug my EmailJS submission so it's only right if I try my best to help you.
I'm able to successfully display my validation error messages by doing the following:
const {
register,
handleSubmit,
formState: { errors },
} = useForm<IContactForm>();
.
.
.
<form>
<input {...register("firstName", { required: "ENTER YOUR FIRST NAME" })}/>
{errors.firstName && errors.firstName.message}
</form>
Only difference I see is that you don't have 'formState: {errors}' for your useForm hook.
I just started learning to code 2 months ago, this week I tried to work with Formik and had this issue where I can't display my ErrorMessage after I added onBlur on the field, before added it, was working normally.
Also, I didn't find another way to work with onBlur, that's why I code it on the field.
I appreciate it if have a hand.

I have a form with several fields. And I am doing the validation as well.
So on the onSubmit it calls to a function handleSubmit and there I am doing the validation.
So if there are any empty fields, they will produce an error and will be shown below each field.
If there are NO errors, it will be route to the /register-success component.
Now my problem is, if there are any empty fields when I click on Register button, those respective errors are being set using setErrors. But it is not being updated to the errors variable right after it is being set.
So unlike in class components I could have used a callback function with setState but in hooks I saw a workaround to use useEffect. It is working, but now I don't know how to redirect the page to /register-success within the useEffect because I can't do it within the handleSubmit because of the errors are not getting updated even after the setErrors
So How can I do the callback operation using react hooks or how can I redirect the page within the useEffect?
Here's my code:
import React, { useState, useEffect } from "react";
import { Link, useHistory } from "react-router-dom";
function Register() {
const [values, setValues] = useState({});
const [errors, setErrors] = useState({});
const handleChange = (event) => {
event.persist();
setValues((values) => ({
...values,
[event.target.name]: event.target.value,
}));
};
useEffect(() => {
if (Object.keys(errors).length === 0) {
// RIDERECT TO THE /register-success ==============================
} else {
// alert("Errors found");
}
}, [errors]);
const validateForm = (values) => {
let allErrors = {};
if (!values.name) {
allErrors.name = "User name is required!";
}
if (!values.phonenumber) {
allErrors.phonenumber = "Phone number is required!";
}
if (!values.email) {
allErrors.email = "Email address is required!";
} else if (!/\S+#\S+\.\S+/.test(values.email)) {
allErrors.email = "Email address is invalid!";
}
if (!values.password) {
allErrors.password = "Please provide the password!";
}
if (!values.confirmpassword) {
allErrors.confirmpassword = "Please confirm the password is the same!";
}
return allErrors;
};
const handleSubmit = (event) => {
if (event) event.preventDefault();
setErrors(validateForm(values));
};
return (
<form onSubmit={handleSubmit}>
<div className="container login-container">
<div className="row">
<div className="col-md-6 login-form-2">

You can do something like that :
const handleSubmit = (event) => {
if (event) event.preventDefault();
const validationErrors = validateForm(values)
if(Object.keys(validationErrors).length > 0) {
setErrors(validationErrors);
return;
}
// REDIRECT TO THE /register-success ==============================
};
If you've got errors redirection won't be triggered and component will re-render with errors updated
In my register form my radio buttons don't work, when I press the create button nothing happens, it doesn't activate the onSubmit function, but if I remove them it gets activated.
Here is my code:
import React from "react";
import { Formik, Field, Form, ErrorMessage } from "formik";
import * as Yup from "yup";
const male = props => (
<input type="radio" value="male" name="gender" {...props} />
);
const female = props => (
<input type="radio" value="female" name="gender" {...props} />
);
export class RegisterPage extends React.Component {
render() {
let { initialValues } = this.state;
return (
<div>
<div>
<h1>Sign Up</h1>
<Formik
initialValues={initialValues}
onSubmit={(
{ email, password, gender },
{ setStatus, setSubmitting }
) => {
setStatus();
authenticationservice.newuser({ email, password, gender }).then(
user => {
const { from } = this.props.location.state || { from: { pathname: "/" } `};`
this.props.history.push(from);
},
error => {
setSubmitting(false);
setStatus(error);
}
);
}}
render={({ errors, status, touched, isSubmitting }) => (
<Form>
<div>
<label htmlFor="email">Email Address</label>
<Field name="email" type="text" />
<ErrorMessage name="email" component="div" />
</div>
<div>
<label htmlFor="gender">Gender</label>
<label>Male</label>
<Field name="gender" as={male} />
<label>Female</label>
<Field name="gender" as={female} />
</div>
<div>
<button type="submit" disabled={isSubmitting}>
Create
</button>
{isSubmitting && <img alt="" src="data:image" />}
</div>
{status && <div>{status}</div>}
</Form>
)}
/>
</div>
</div>
);
}
}
I'm not sure what happens because I don't get any error codes, there is just not happening anything
