jQuery Ajax form Submit example PHP MySQL
Use the following steps to easily submit form using jQuery ajax in PHP MySQL with validation:
- Create a Database Connection File
- Create An Ajax Form in PHP
- Create An Ajax Data Store File
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:
<?php
$servername='localhost';
$username='root';
$password='';
$dbname = "my_db";
$conn=mysqli_connect($servername,$username,$password,"$dbname");
if(!$conn){
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">
<div class="form-group">

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

</div>
<div class="form-group">

<input type="text" name="mobile" id="mobile" class="form-control" value="" maxlength="12" >
</div>
<input type="submit" class="btn btn-primary" name="submit" value="submit">
</form>
</div>
</div>
</div>
<script type="text/javascript">
$(document).ready(function($){
// hide messages
$("#error").hide();
$("#show_message").hide();
// on submit...
$('#ajax-form').submit(function(e){
e.preventDefault();
$("#error").hide();
//name required
var name = $("input#name").val();
if(name == ""){
$("#error").fadeIn().text("Name required.");
$("input#name").focus();
return false;
}
// email required
var email = $("input#email").val();
if(email == ""){
$("#error").fadeIn().text("Email required");
$("input#email").focus();
return false;
}
// mobile number required
var mobile = $("input#mobile").val();
if(mobile == ""){
$("#error").fadeIn().text("Mobile number required");
$("input#mobile").focus();
return false;
}
// ajax
$.ajax({
type:"POST",
url: "project_folder_name/ajax-form-save.php",
data: $(this).serialize(), // get all form field value in serialize form
success: function(){
$("#show_message").fadeIn();
//$("#ajax-form").fadeOut();
}
});
});
return false;
});
</script>
</body>
</html>
3. Create Ajax Form PHP File
Now we will create a new file name ajax-form-store.php and update the below code into your ajax-form-store.php file.
The below code is used to store form data into a MySQL database table name customers. If form successfully submitted to the database, it will return success message otherwise it returns an error.
<?php
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);
}
mysqli_close($conn);
?>
