Razorpay Payment Gateway Integration using PHP

Razorpay Payment Gateway features:

  • Accept All the payment methods like debit card, credit card, netbanking,UPI and wallets.
  • Razorpay payment gateway is very safe and secure
  • Easy to integration
  • Payment gateway kit available on multiple programming language
  • UPI and Multi Bank EMI options

Before starts to implement the Razorpay Payment Gateway Integration using PHP with cURL, look files structure, we are splits the process in several parts so it will be easy to understand the overall developing process.
Step1: Create a file constants.php and define Key ID and Secret Key 

<?php 
define('RAZOR_KEY_ID', 'rzp_test_XXXXXXXXXXXXXXXX');
define('RAZOR_KEY_SECRET', 'XXXXXXXXXXXX');
?>

Note:please guys never share your secret key to anyone.

Step 2: Create another php file named index.php

in the below index.php code , we are declaring amount , currency , success URL and failure URL into some hidden input tags. so it will automatic redirect to success or failure page according to there response status.

<?php 
require_once "constants.php";
include('templates/header.php');
?>
<form name="razorpay_frm_payment" class="razorpay-frm-payment" id="razorpay-frm-payment" method="post">
<input type="hidden" name="merchant_order_id" id="merchant_order_id" value="12345"> 
<input type="hidden" name="language" value="EN"> 
<input type="hidden" name="currency" id="currency" value="INR"> 
<input type="hidden" name="surl" id="surl" value="http://localhost/razorpay-payment-gateway-integration-using-php/success.php"> 
<input type="hidden" name="furl" id="furl" value="http://localhost/razorpay-payment-gateway-integration-using-php/failed.php">

    // obj        
    var objrzpv1 = new Razorpay(razorpay_options);
    objrzpv1.open();
        e.preventDefault();
            
});
</script>

Step 3: Create a file named callback.php
The file handles the payment process. 

<?php
require_once "constants.php";
// initialized cURL Request
function get_curl_handle($payment_id, $data) {
    $url = 'https://api.razorpay.com/v1/payments/' . $payment_id . '/capture';
    $key_id = RAZOR_KEY_ID;
    $key_secret = RAZOR_KEY_SECRET;
    $params = http_build_query($data);
    //cURL Request
    $ch = curl_init();
    //set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_USERPWD, $key_id . ':' . $key_secret);
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
    return $ch;
}
if (!empty($_POST['razorpay_payment_id']) && !empty($_POST['merchant_order_id'])) {
$json = array();
$razorpay_payment_id = $_POST['razorpay_payment_id'];
$merchant_order_id = $_POST['merchant_order_id'];
$currency_code = $_POST['currency_code_id'];
// store temprary data
$dataFlesh = array(
    'card_holder_name' => $_POST['card_holder_name_id'],
    'merchant_amount' => $_POST['merchant_amount'],
    'merchant_total' => $_POST['merchant_total'],
    'surl' => $_POST['merchant_surl_id'],
    'furl' => $_POST['merchant_furl_id'],
    'currency_code' => $currency_code,
    'order_id' => $_POST['merchant_order_id'],
    'razorpay_payment_id' => $_POST['razorpay_payment_id'],
);

$paymentInfo = $dataFlesh;
$order_info = array('order_status_id' => $_POST['merchant_order_id']);
$amount = $_POST['merchant_total'];
$currency_code = $_POST['currency_code_id'];
// bind amount and currecy code
$data = array(
    'amount' => $amount,
    'currency' => $currency_code,
);
$success = false;
$error = '';
try {
    $ch = get_curl_handle($razorpay_payment_id, $data);
    //execute post
    $result = curl_exec($ch);
    $data = json_decode($result);
   
    $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    if ($result === false) {
        $success = false;
        $error = 'Curl error: ' . curl_error($ch);
    } else {
        $response_array = json_decode($result, true);
        //Check success response
        if ($http_status === 200 and isset($response_array['error']) === false) {
            $success = true;
        } else {
            $success = false;
            if (!empty($response_array['error']['code'])) {
                $error = $response_array['error']['code'] . ':' . $response_array['error']['description'];
            } else {
                $error = 'Invalid Response <br/>' . $result;
            }
        }
    }
    //close connection
    curl_close($ch);
} catch (Exception $e) {
    $success = false;
    $error = 'Request to Razorpay Failed';
}
if ($success === true) {
    if (!$order_info['order_status_id']) {
        $json['redirectURL'] = $_POST['merchant_surl_id'];
    } else {
        $json['redirectURL'] = $_POST['merchant_surl_id'];
    }
} else {
    $json['redirectURL'] = $_POST['merchant_furl_id'];
}
$json['msg'] = '';
} else {
$json['msg'] = 'An error occured. Contact site administrator, please!';
}
header('Content-Type: application/json');
echo json_encode($json);
?>

Step 4: Put the below script code in index.php file
We will use the chekout.js of Razorpay payment gateway for deduction of payment. 

<script src="https://checkout.razorpay.com/v1/checkout.js"></script>
<script type="text/javascript">
  jQuery(document).on('click', '#razor-pay-now', function (e) {
    var total = (jQuery('form#razorpay-frm-payment').find('input#amount').val() * 100);
    var merchant_order_id = jQuery('form#razorpay-frm-payment').find('input#merchant_order_id').val();
    var merchant_surl_id = jQuery('form#razorpay-frm-payment').find('input#surl').val();
    var merchant_furl_id = jQuery('form#razorpay-frm-payment').find('input#furl').val();
    var card_holder_name_id = jQuery('form#razorpay-frm-payment').find('input#billing-name').val();
    var merchant_total = total;
    var merchant_amount = jQuery('form#razorpay-frm-payment').find('input#amount').val();
    var currency_code_id = jQuery('form#razorpay-frm-payment').find('input#currency').val();
    var key_id = "<?php echo RAZOR_KEY_ID; ?>";
    var store_name = 'shortlearner';
    var store_description = 'Payment';
    var store_logo = 'img/logo.png';
    var email = jQuery('form#razorpay-frm-payment').find('input#billing-email').val();
    var phone = jQuery('form#razorpay-frm-payment').find('input#billing-phone').val();
    
    jQuery('.text-danger').remove();

    if(card_holder_name_id=="") {
      jQuery('input#billing-name').after('<small class="text-danger">Please enter full mame.</small>');
      return false;
    }
    if(email=="") {
      jQuery('input#billing-email').after('<small class="text-danger">Please enter valid email.</small>');
      return false;
    }
    if(phone=="") {
      jQuery('input#billing-phone').after('<small class="text-danger">Please enter valid phone.</small>');
      return false;
    }
    
    var razorpay_options = {
        key: key_id,
        amount: merchant_total,
        name: store_name,
        description: store_description,
        image: store_logo,
        netbanking: true,
        currency: currency_code_id,
        prefill: {
            name: card_holder_name_id,
            email: email,
            contact: phone
        },
        notes: {
            soolegal_order_id: merchant_order_id,
        },
        handler: function (transaction) {
            jQuery.ajax({
                url:'callback.php',
                type: 'post',
                data: {razorpay_payment_id: transaction.razorpay_payment_id, merchant_order_id: merchant_order_id, merchant_surl_id: merchant_surl_id, merchant_furl_id: merchant_furl_id, card_holder_name_id: card_holder_name_id, merchant_total: merchant_total, merchant_amount: merchant_amount, currency_code_id: currency_code_id}, 
                dataType: 'json',
                success: function (res) {
                    if(res.msg){
                        alert(res.msg);
                        return false;
                    } 
                    window.location = res.redirectURL;
                }
            });
        },
        "modal": {
            "ondismiss": function () {
                // code here
            }
        }
    };
    // obj        
    var objrzpv1 = new Razorpay(razorpay_options);
    objrzpv1.open();
        e.preventDefault();
            
});
</script>

Step 5: now in the second last step we are creating a success.php file
so if transaction status is success than success.php page will show the message of transaction success.

<?php include('templates/header.php'); ?>
<section class="showcase">
   <div class="container">
    <div class="text-center">
      <h1 class="display-3">Thank You!</h1>
      <p class="lead">Your payment has been received successfully.</p>
      <hr>
      <p>
        Having trouble? <a href="mailto:info@localhost">Contact us</a>
      </p>
      <p class="lead">
        <a class="btn btn-primary btn-sm" href="#" role="button">Continue to homepage</a>
      </p>
    </div>
    </div>
</section>
<br><br><br><br><br><br>
<?php include('templates/footer.php');?>

Step 6: Create a file named failed.php

<?php include('templates/header.php');?>
<section class="showcase">
   <div class="container">
    <div class="text-center">
      <h1 class="display-3">Thank You!</h1>
      <p class="lead text-danger">Your transaction has been declined.</p>
      <hr>
      <p>
        Having trouble? <a href="mailto:info@localhost">Contact us</a>
      </p>
      <p class="lead">
        <a class="btn btn-primary btn-sm" href="#" role="button">Continue to homepage</a>
      </p>
    </div>
    </div>
</section>
<br><br><br><br><br><br>
<?php include('templates/footer.php');?>

Create header.php and footer.php section of the web page.
