jQuery Ajax Form Submit With PHP Processing

jQuery has main functions programmed into it. We will be making use of the following functions in jQuery.

The .ready() method offers a way to run JavaScript code as soon as the page's Document Object Model (DOM) becomes safe to manipulate.
The click() event occurs when an element is clicked. The click() method triggers the click event, or attaches a function to run when a click event occurs.
The .val() method is primarily used to get the values of form elements such as input , select and textarea .

Scripts for jQuery Tutorial

Create a file and call it index.php. Put the following code into the file.

<!DOCTYPE html>
<html>
<head>
<title>Submit Form Using AJAX and jQuery</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
</head>
<body>
<input id="name" type="text" placeholder="Your Name">
<input id="email" type="text" placeholder="email">
<input id="submit" type="button" value="Submit">
<div id="display"></div><script>
$(document).ready(function(){
$("#submit").click(function(){
var name = $("#name").val();
var email = $("#email").val();
var dataString = 'name1='+ name + '&email1='+ email;
if(name==''||email=='')
{
$("#display").html("Please Fill All Fields");
}
else
{
$.ajax({
type: "POST",
url: "processor.php",
data: dataString,
cache: false,
success: function(result){
$("#display").html(result);
}
});
}
return false;
});
});
</script>
</body>
</html>

Now create a file and call it processor.php and put the following code into the file.

<?php $name=$_POST['name1']; 
$email=$_POST['email1']; 
echo "Form Submitted Succesfully"; 
echo '<br/>'; 
echo $name; 
echo '<br/>';
 echo $email; ?>
