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

                        <input type="email" name="email" id="email" class="form-control" value="" maxlength="30" >
                    </div>

                    <div class="form-group">

                        <input type="text" name="mobile" id="mobile" class="form-control" value="" maxlength="12" >

                </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>

Step 3 – Create Store Data In DB File

Create a new file name ajax-form-save.php and update the below code into ajax-form-save.php file.

<?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);

?>

The Above 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.
