I wrote a php code that insert data into the database without refreshing the page. But unfortunately there is a error. Please help me to fix it. The error I got was I can't input any data to the database
Here in the message.php i get the data and post it to the insertmsg.php file using ajax.
messages.php
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function () {
$('.sendmsgbutton').click(function (e) {
e.preventDefault();
var from_user = $('#from_user').val();
var to_user = $('#to_user').val();
var msg = $('#msg').val();
$.ajax
({
type: "POST",
url: "insertmsg.php",
data: {"from_user": from_user,
"to_user": to_user,
"msg": msg}
success: function (data) {
$('#chatarea')[0].reset();
}
});
});
});
</script>
</head>
<?php
$username = $_SESSION['username'];
if (!isset($_SESSION['username']))
{header("Location: login.php");
die();
}
$fuck = "yohan";
?>
<div class="main">
<!-- PHP FOR READ THE DATA OF THE QUESTION THAT THE USER CLICKED -->
<div class="friendslist">
<?php
if (isset($_GET['id'])) {
global $con;
$id = htmlentities(mysqli_real_escape_string($con,$_GET['id']));
$select = "SELECT * FROM `users` WHERE id='$id'";
$result = $con->query($select);
while ($row = mysqli_fetch_array($result)) {
$name = $row['username'];
echo "@$name";
}
echo "<div class='chatbox'>
</div>
<div class='sendmsgarea'>
<form method='post' action='' id='chatarea'>
<input type='hidden' id='from_user' value='$username'>

insertmsg.php
<?php
//Database connection
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db = 'mess';
$conn = mysqli_connect($dbhost, $dbuser, $dbpass , $db) or die($conn);
//insert into database
if(!empty($_POST)) {
$from_user = $_POST["from_user"];
