                        <div class="form-group">
                            <strong>Name</strong>
                            <input type="text" name="name" class="form-control" placeholder="Enter Name" required>
                        </div>
                    </div>

                        </div>

                        </div>

                    <div class="col-md-12">
                        <button type="submit" class="btn btn-primary">Submit</button>
                    </div>
                </div>
            </form>
        </div>
    </body>
</html>

Make Payment Process

Now, we need to create a new PHP file name payment-proccess.php.
In this file we will use the instamojo package and do further payment process in this file.

<?php
    require_once('vendor/autoload.php');
    $API_KEY = "test_d883b3a8d2bc1adc7a535506713";
    $AUTH_TOKEN = "test_dc229039d2232a260a2df3f7502";
    $URL = "https://test.instamojo.com/api/1.1/";
    $api = new Instamojo\Instamojo($API_KEY, $AUTH_TOKEN, $URL);

    try {
        $response = $api->paymentRequestCreate(array(
            "purpose" => "FIFA 16",
            "amount" => $_POST["amount"],
            "buyer_name" => $_POST["name"],
            "send_email" => true,
            "email" => $_POST["email"],
            "phone" => $_POST["phone"],
            "redirect_url" => "http://localhost/instamojo/payment-success.php"
        ));
        header('Location: ' . $response['longurl']);
        exit();
    } catch (Exception $e) {
        print('Error: ' . $e->getMessage());
    }
?>

Create a Success Page

In the final step, we need to create one file name payment-success.php. Here we will show payment-related info like payer name, email, mobile, the status of payment etc.

                    <?php

                        $API_KEY = "test_d883b3a8d2bc1adc7a535506713";
                        $AUTH_TOKEN = "test_dc229039d2232a260a2df3f7502";
                        $URL = "https://test.instamojo.com/api/1.1/";
                        $api = new Instamojo\Instamojo($API_KEY, $AUTH_TOKEN,$URL);
                        $payid = $_GET["payment_request_id"];

                        try {
                            $response = $api->paymentRequestStatus($payid);
                            echo "<h5>Payment ID: " . $response['payments'][0]['payment_id'] . "</h5>" ;
                            echo "<h5>Payment Name: " . $response['payments'][0]['buyer_name'] . "</h5>" ;
                            echo "<h5>Payment Email: " . $response['payments'][0]['buyer_email'] . "</h5>" ;
                            echo "<h5>Payment Mobile: " . $response['payments'][0]['buyer_phone'] . "</h5>" ;
                            echo "<h5>Payment status: " . $response['payments'][0]['status'] . "</h5>" ;
                            echo "<pre>";
                        }
                        catch (Exception $e) {
                            print('Error: ' . $e->getMessage());
                        }
                    ?>
                <br>
                <p><a class="btn btn-warning" target="_blank" href="https://www.tutsmake.com/"> Tutsmake.com
