jQuery AJAX Form Submit In PHP + MySQL Example

Follow the below given steps to easily create and submit ajax form in PHP + MySQL with client-side validation:

First of all, go to your PHPMyAdmin and create a table name customers with the following fields: name, email, mobile.

1. First Create a Database Connection File

In this step, you will create a file name db.php and update the below code into your file.

The below code is used to create a MySQL database connection in PHP. When we insert form data into MySQL database, there we will include this file:

	$dbname = "my_db";
		  die('Could not Connect MySql Server:' .mysql_error());

2. Create An Ajax Form in PHP

In this step, you need to create an ajax form and update the below code into your ajax-form.php file.

<form action="javascript:void(0)" method="post" id="ajax-form">

<input type="text" name="name" id="name" class="form-control" value="" maxlength="50" >
<div class="form-group ">

<div class="form-group">
<input type="text" name="mobile" id="mobile" class="form-control" value="" maxlength="12" >
<input type="submit" class="btn btn-primary" name="submit" value="submit">
<script type="text/javascript">
// hide messages 
// on submit...
//name required
var name = $("input#name").val();
if(name == ""){
$("#error").fadeIn().text("Name required.");
return false;
// email required
var email = $("input#email").val();
if(email == ""){
$("#error").fadeIn().text("Email required");
return false;
// mobile number required
var mobile = $("input#mobile").val();
if(mobile == ""){
$("#error").fadeIn().text("Mobile number required");
return false;
// ajax
url: "project_folder_name/ajax-form-save.php",
data: $(this).serialize(), // get all form field value in serialize form
success: function(){
return false;

3. Create Ajax Form PHP File

require_once "db.php";
$name = mysqli_real_escape_string($conn, $_POST['name']);
$email = mysqli_real_escape_string($conn, $_POST['email']);
$mobile = mysqli_real_escape_string($conn, $_POST['mobile']);
if(mysqli_query($conn, "INSERT INTO customers(name, email, mobile) VALUES('" . $name . "', '" . $email . "', '" . $mobile . "')")) {
echo '1';
} else {
echo "Error: " . $sql . "" . mysqli_error($conn);
