send information to database without having page reload

I have a site where you type into a text box and it will send what I wrote to my database.

I have been stuck with my page having to reload which is very troubling in my case. i am not familiar with ajax but i have heard it can be used to complete this task. i have 2 files one is called demo.php this sends the information to the server and at this time has a header that redirects me back to that page which i don't want.

I want to be able to keep sending things data to the sever without the page reloading. the other page is the index.php this is were i right into the text box and send the text to my database both files are listed below.

this is the demo.php 

<?php
header("Location: http://mywebsite.com"); 
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$value = $_POST['firstname'];

$sql = "INSERT INTO MyGuests (firstname) VALUES ('$value')";


if ($conn->query($sql) === TRUE) {
    echo "working";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
this is the forum on index.php were i enter the information and send it. i need it to stay on that page and not reload in any way. 
 <form action="demo.php" method="post" />
<p> <input id="textbox" type="text" name="firstname" placeholder="Enter What You Want Your Message To Be" /></p>
<input id="textbox1" type="submit" value="Submit" />
</form>

my second attempt at index.php

<!DOCTYPE html>
<html>
<head>
 <link rel="stylesheet" href="navigation.css href="navigation/navigation.css">
  <link rel="stylesheet" href="navigation/navigation.css">
  <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.js"></script>


</head>
<body>
<form action="ajax_target.php" method="post" id="ajax-form">
<input type="text" name="firstname" />
<input type="button" name ="send" onclick="return f(this.form ,this.form.fname ,this.form.lname) " >
</form>
</body>

<script>
function submitForm(form){
    var url = form.attr("action");
    var formData = $(form).serializeArray();
    $.post(url, formData).done(function (data) {
        alert(data);
    });
}
$("#ajax-form").submit(function() {
submitForm($(this));
});
</script>
</html>

your html/index form consists

<!DOCTYPE html>
<html>
<head>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.js"></script>
</head>
<body>
<form action="demo.php" method="post" id="ajax-form">
<input type="text" name="firstname" />
<input type="submit" name="send" value="send" >
</form>
</body>

<script>
function submitForm(form){
    var url = form.attr("action");
    var formData = $(form).serializeArray();
    $.post(url, formData).done(function (data) {
        alert(data);
    });
}
$("#ajax-form").submit(function() {
submitForm($(this));
return false;
});
</script>
</html>

your demo.php includes

<?php
//your db insertion goes here.
echo "inserted successfully";
?>

You can have two files/pages for your purpose:

1. Form page
2. Ajax processing page where you request values will be inserted into your database.

Add this to your head tag

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.js"></script>

Steps to utilize ajax:

1. Include jquery library in form page
2. Include html form
3. Save values from ajax, that means process that ajax

HTML form suppose to be like this:

<form action="ajax_target.php" method="post" id="ajax-form">
<input type="text" name="firstname" />
<input type="submit" name="send" value="send" >
</form>

Ajax call:

    function submitForm(form){
    var url = form.attr("action");
    var formData = $(form).serializeArray();
    $.post(url, formData).done(function (data) {
        alert(data);
    });
}
$("#ajax-form").submit(function() {
submitForm($(this));
return false;
});

ajax_target.php handles formData, its validation and insertion to database.
