    <span id="response">
  1. First, we write <! DOCTYPE html> which we used as the instruction to the web browser about what version of HTML file is written in.
  2. Secondly, the <html> tag is used to indicate the beginning of an HTML document.
  3. As mentioned above, the <head> tag contains information about the web page. In this tag, a <title> tag is used which helps us to specify a webpage title.
  4. Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
  5. Adding external CSS stylesheet into the <head> tag
  6. Thirdly, the <body> tag is used to define the webpage body. All the contents to show on the website are written here.
  7. <h1> tag used to add heading here and also adding the inline CSS here
  8. Created <input> tag for Name, Contact, and a button with the onlick function of Send_Data()
  9. Also created <span> to display message
  10. Now created a <script> tag to write JavaScript
  11. Declaring the function for Send_Data()
  12. creating a variable for name and contact with document.getElementById()
  13. also a variable for new XMLHttpRequest()
  14. using the open() method to create a connection with the server for data.php file
  15. setRequestHeader() to add some HTTP header.
  16. Using the onreadystatechange() function add the <span> id ‘response’ with document.getElementById() within it.
  17. Now use the send() method to send the request object to the server

Now let’s see the php code for data.php,

PHP Code:

if(isset($_POST['name'])) {
    $name = $_POST['name'] ;
    $contact = $_POST['contact'] ;
$con = mysqli_connect("localhost", "root","", "demo") ;
$sql = "INSERT INTO `info`(`name`,`conatct`) VALUES ('$name','$contact');";
$result=mysqli_query($con,$sql) ;
if($result==true) {
    echo "<h3> INSERTED! <?h3>" ;
  1. At first opening the php file using <?php
  2. Creating if statement with isset() function with super global variable $_POST.
  3. Creating variable for $name and $contact with the $_POST method
  4. Using mysqli_connect() with the hostname, username and password
  5. INSERT INTO to insert new records and VALUES to specify the values.
  6. Now using mysqli_query()
  7. Then using echo to display the success message.
