2. Create a controller file Checkout.php in the applications/controllers/ directory.
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Razorpay extends CI_Controller {
public function index() {
$this->checkout();
}
public function checkout() {
$data['title'] = 'Checkout Payment | Infovistar.in';
$data['callback_url'] = base_url().'razorpay/callback';
$data['surl'] = base_url().'razorpay/success';;
$data['furl'] = base_url().'razorpay/failed';;
$data['currency_code'] = 'INR';
$this->load->view('razorpay/checkout', $data);
}
// initialized cURL Request
private function curl_handler($payment_id, $amount) {
$url = 'https://api.razorpay.com/v1/payments/'.
$payment_id.'/capture';
$key_id = "YOUR KEY ID";
$key_secret = "YOUR KEY SECRET";
$fields_string = "amount=$amount";
//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, $fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
return $ch;
}
// callback method
public function callback() {
print_r($this->input->post());
if (!empty($this->input->post('razorpay_payment_id')) &&
!empty($this->input->post('merchant_order_id'))) {
$razorpay_payment_id = $this->input->post('razorpay_payment_id');
$merchant_order_id = $this->input->post('merchant_order_id');
$this->session->set_flashdata('razorpay_payment_id',
$this->input->post('razorpay_payment_id'));
$this->session->set_flashdata('merchant_order_id',
$this->input->post('merchant_order_id'));
$currency_code = 'INR';
$amount = $this->input->post('merchant_total');
$success = false;
$error = '';
try {
$ch = $this->curl_handler($razorpay_payment_id, $amount);
//execute post
$result = curl_exec($ch);
$http_status = curl_getinfo($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 = 'RAZORPAY_ERROR:Invalid Response <br/>'.
$result;
}
}
}
//close curl connection
curl_close($ch);
} catch (Exception $e) {
$success = false;
$error = 'Request to Razorpay Failed';
}
if ($success === true) {
if(!empty($this->session->userdata('ci_subscription_keys'))) {
$this->session->unset_userdata('ci_subscription_keys');
}
if (!$order_info['order_status_id']) {
redirect($this->input->post('merchant_surl_id'));
} else {
redirect($this->input->post('merchant_surl_id'));
}
} else {
redirect($this->input->post('merchant_furl_id'));
}
} else {
echo 'An error occured. Contact site administrator, please!';
}
}
public function success() {
$data['title'] = 'Razorpay Success | Infovistar.in';
echo "<h4>Your transaction is successful</h4>";
echo "<br/>";
echo "Transaction ID: ".$this->session->flashdata('razorpay_payment_id');
echo "<br/>";

echo "<br/>";
echo "Transaction ID: ".$this->session->flashdata('razorpay_payment_id');
echo "<br/>";
echo "Order ID: ".$this->session->flashdata('merchant_order_id');
