I have made a signup/login/logout page which works perfectly fine, however I wanted to add an additional field in the register page for user name, and I wanted the username to display in the profile page.
I was able to inset the username field into the register page, and I have a name section on the profile page which also shows up when the profile page loads, however, when I input a user name in the register page, it does not appear in the profile page.
Can anyone please help me figure this out? I really appreciate the help everyone. My first post here :) just recently started my developer journey

While using the navigate and passing email in it, I am getting email in another component for first time only. Second time it is becoming undefined.
Please help me here to How can I send data using navigate from one component to another component. Here, after clicking on login button, it should redirect to desired page and should pass the details object.
Also I want to pass all the data available in details object to another component.

I have a form,thats data are saved in the state to be sent to the backend server.
i am handling the form with handleSubmit function and useEffect hook, where the handleSubmit prevents the form from being submitted unless it calls the validation function, in the useEffect I check if there are any errors using if condition and then console.log my data.
now I want to post the data hold in the state -the state is sent as a props to me- but I am confused whether to put the request in the HandleSubmit function or in the useEffect inside the body of the if condition.
import react, { Component, useState, useEffect } from 'react';
import {useNavigate } from 'react-router-dom';
import axios from 'axios';
import './sign.css';
const SignA = (props) => {
const navigate = useNavigate();
const [formErrors, setFormErrors] = useState({});
const [isSubmit, setIsSubmit] = useState(false);
const handleSubmit = (err) => {
err.preventDefault();
setFormErrors(validate(props.data));
setIsSubmit(true);
}
useEffect(() => {
console.log(Object.keys(formErrors).length);
if (Object.keys(formErrors).length === 0 && isSubmit) {
console.log('console the props data', props.data)
//here is where I think the post request should be put
if (isSubmit) {
return (navigate('/profileadmin'))
}
}
}, [formErrors])
const validate = (values) => {
const errors = {};
const regex = /^[^\s#]+#[^\s#]+\.[^\s#]{2,}$/i;
if (!values.firstname) {
errors.firstname = 'firstname is required!';
}
if (!values.lastname) {
errors.lastname = 'lastname is required!';
}
if (!values.mobile) {
errors.mobile = 'mobile is required!';
}
if (!values.email) {
errors.email = 'email is required!';
} else if (!regex.test(values.email)) {
errors.email = 'this is not a valid email format!'
}
return errors;
}

this is the request
axios.post('', props.data)
.then(res => console.log('post res', res))
.catch(error => {
console.error('There was an error in post request!', error);
});
You don't necessarily need useEffect here.
Here is how you can implement such thing:
Declare a state to hold form values:
const [formData, setFormData] = useState({})
Declare function to set the state:
const handleChange = (name, value) => {
setFormData({...formData, [name]: value})
}
Input onChange to capture:
// handleChange has two parameters
<input
type="text"
placeholder="First name"
name="firstname"
id='firstName'
value={props.data.firstname}
onChange={(event) => handleChange('firstName', event.target.value)}
/>
function for calling post axios post request
const handleSubmit = () => {
//check for validations code here
// if validations are right then post request here
// this will give you all the fields like firstName: "", lastName: ""
let requestBody = {
...formData
}
axios.post("url", requestBody).then((res)=> {
//your code here
})
}
I'm pretty new to javascript, and I am trying to figure out how to calculate sales tax based off of US states. In my code, I attempted to use an if else statement based off of the input value of state to accomplish this. However, no matter what I put in for the value of state the tax is determined based off of 8.75%, and I'm not sure what I am doing wrong. I would really appreciate any help or advice on how to fix this problem.
Thank you

Your code should look like this:
cart.shippingAddress.state === 'New York'|| cart.shippingAddress.state === 'NY'
Your current code is testing if the string "NY" is true or not, and that evaluates to true in your boolean test, so you're always getting the 8.75% tax rate.
I have a problem: I have two pages, one named /login and the other one is called /app.
My problem is that I don't know how to pass props from /login to /app. In /app I want to show the person who logged in a welcome message with his name like: "Welcome Kazim". Hope you guys can help me. There is no problem to link from /login to /app but the props won't get passed.

import Testchat from "../components/testchat/Testchat";
function Chat(props) {

Given route push with state:
history.push({

state: {
email: 'irgendwas#web.de',

You can access the route state on the location object on the receiving route. You can access the location object via the useLocation React hook.
function Chat(props) {
const { state } = useLocation();
const { name } = state;
return (
<div>
<h1>Willkommen {name}</h1>
<Testchat></Testchat>
