Stripe payment gateway integration

Stripe payment gateway offers 2 ways of integration in PHP –

Stripe checkout integration
Stripe custom integration (Stripe.js)

Strip checkout integration:

The easiest way to integrate Stripe is via Checkout, an embedded tool that takes care of building an HTML form, validating user input, and securing your customers’ card data. Using Checkout, sensitive credit card information is sent directly to Stripe, and does not touch your server. Stripe returns to your site a token representation of the card, and this token can then be used in a charge request.

Embedding Checkout in your site

To get started, add the following code to your payment page:

<form action="/your-charge-code" method="POST">
  <script
    src="https://checkout.stripe.com/checkout.js" class="stripe-button"
    data-key="pk_test_6pRNASCoBOKtIshFeQd4XMUh"
    data-amount="999"
    data-name="ILovePHP.net"
    data-description="Donation"
    data-image="http://www.ilovephp.net/wp-content/uploads/2016/03/small-3.jpg"
    data-locale="auto"
    data-zip-code="true">
  </script>
</form>

<script

src="https://checkout.stripe.com/checkout.js" class="stripe-button"

data-key="pk_test_6pRNASCoBOKtIshFeQd4XMUh"

data-amount="999"

data-name="ILovePHP.net"

data-description="Donation"

data-image="http://www.ilovephp.net/wp-content/uploads/2016/03/small-3.jpg"

data-locale="auto"

data-zip-code="true">

</script>

</form>

Stripe custom integration (Stripe.js):

For a more custom approach, you can instead use Stripe with your own payment form via Stripe.js.

Processing payments with Custom Stripe integration has two components:

Securely collecting the payment details
Using the collected payment method in a charge request

Below code example show you demonstrate you the custom stripe integration with stripe.js.

<?php
// Stripe library
require 'stripe/Stripe.php';

$params = array(
	"testmode"   => "on",
	"private_live_key" => "sk_live_xxxxxxxxxxxxxxxxxxxxx",
	"public_live_key"  => "pk_live_xxxxxxxxxxxxxxxxxxxxx",
	"private_test_key" => "sk_test_xxxxxxxxxxxxxxxxxxxxx",
	"public_test_key"  => "pk_test_xxxxxxxxxxxxxxxxxxxxx"
);

if ($params['testmode'] == "on") {
	Stripe::setApiKey($params['private_test_key']);
	$pubkey = $params['public_test_key'];
} else {
	Stripe::setApiKey($params['private_live_key']);
	$pubkey = $params['public_live_key'];
}

if(isset($_POST['stripeToken']))
{
	$amount_cents = str_replace(".","","10.52");  // Chargeble amount
	$invoiceid = "14526321";                      // Invoice ID
	$description = "Invoice #" . $invoiceid . " - " . $invoiceid;
	
	try {

		$charge = Stripe_Charge::create(array(		 
			  "amount" => $amount_cents,
			  "currency" => "usd",
			  "source" => $_POST['stripeToken'],
			  "description" => $description)			  
		);

		if ($charge->card->address_zip_check == "fail") {
			throw new Exception("zip_check_invalid");
		} else if ($charge->card->address_line1_check == "fail") {
			throw new Exception("address_check_invalid");
		} else if ($charge->card->cvc_check == "fail") {
			throw new Exception("cvc_check_invalid");
		}
		// Payment has succeeded, no exceptions were thrown or otherwise caught				

		$result = "success";

	} catch(Stripe_CardError $e) {			

	$error = $e->getMessage();
		$result = "declined";

	} catch (Stripe_InvalidRequestError $e) {
		$result = "declined";		  
	} catch (Stripe_AuthenticationError $e) {
		$result = "declined";
	} catch (Stripe_ApiConnectionError $e) {
		$result = "declined";
	} catch (Stripe_Error $e) {

	} catch (Exception $e) {

		if ($e->getMessage() == "zip_check_invalid") {
			$result = "declined";
		} else if ($e->getMessage() == "address_check_invalid") {
			$result = "declined";
		} else if ($e->getMessage() == "cvc_check_invalid") {
			$result = "declined";
		} else {
			$result = "declined";
		}		  
	}
	
	echo "<BR>Stripe Payment Status : ".$result;
	
	echo "<BR>Stripe Response : ";
	
	print_r($charge); exit;
}
