I use the samples (https://github.com/stripe-samples/checkout-single-subscription/tree/master/server/php) from Stripe to create a subscription. What I don't really understand, how can I pass metadata from my index.html over script.js to the create-checkout-session.php.
I thought I just add data attributes to the index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Stripe</title>
<meta name="description" content="A demo of Stripe Payment Intents" />
<link rel="icon" href="favicon.ico" type="image/x-icon" />
<script src="https://js.stripe.com/v3/"></script>
<script src="./script.js" defer></script>
</head>
<body>
<div class="sr-root">
<div class="sr-main" style="display: flex;">
<div class="sr-container">
<section class="container">
<button id="basic-plan-btn" data-partner="name" data-package="basic">USD 6.90</button>
</section>
<section class="container">
<button id="pro-plan-btn" data-partner="name" data-package="premium">USD 11.90</button>
</section>
</div>
</div>
</div>
</body>
</html>
then I have to read them somehow out in the script.js. But that I don't really figure out how.
// Create a Checkout Session with the selected plan ID
var createCheckoutSession = function(priceId) {
return fetch("/fileadmin/restaurant/stripe/create-checkout-session.php", {
method: "POST",
headers: {
"Content-Type": "application/json"
},
body: JSON.stringify({
priceId: priceId,
partner: 'name',
package: 'premium'
})
}).then(function(result) {
return result.json();
});
};
// Handle any errors returned from Checkout
var handleResult = function(result) {
if (result.error) {
var displayError = document.getElementById("error-message");
displayError.textContent = result.error.message;
}
};
/* Get your Stripe publishable key to initialize Stripe.js */
fetch("/fileadmin/restaurant/stripe/config.php")
.then(function(result) {
return result.json();
})
.then(function(json) {
var publishableKey = json.publishableKey;
var basicPriceId = json.basicPrice;
var proPriceId = json.proPrice;
var stripe = Stripe(publishableKey);
// Setup event handler to create a Checkout Session when button is clicked
document
.getElementById("basic-plan-btn")
.addEventListener("click", function(evt) {
createCheckoutSession(basicPriceId).then(function(data) {
// Call Stripe.js method to redirect to the new Checkout page
stripe
.redirectToCheckout({
sessionId: data.sessionId
})
.then(handleResult);
});
});
// Setup event handler to create a Checkout Session when button is clicked
document
.getElementById("pro-plan-btn")
.addEventListener("click", function(evt) {
createCheckoutSession(proPriceId).then(function(data) {
// Call Stripe.js method to redirect to the new Checkout page
stripe
.redirectToCheckout({
sessionId: data.sessionId
})
.then(handleResult);
});
});
});
by that I receive them in the create-checkout-session.php
<?php
require_once 'shared.php';
$domain_url = $config['domain'];
$checkout_session = \Stripe\Checkout\Session::create([
'success_url' => $domain_url . 'success.php?session_id={CHECKOUT_SESSION_ID}',
'cancel_url' => $domain_url . 'canceled.php',
'payment_method_types' => ['card'],
'mode' => 'subscription',
'allow_promotion_codes' => true,
'line_items' => [[
'price' => $body->priceId,
'quantity' => 1,
]],
'subscription_data' => ['trial_period_days' => 60],
'metadata' => [
'partner' => $body->partner,
'package' => $body->package
],
]);
echo json_encode(['sessionId' => $checkout_session['id']]);
Thank You.
