I am struggling for a long period of time to implement Stripe in my Laravel app, but I've encountered a lot of problems. I did somehow implemented the logic but I cannot or I don't know how I can send the current order total to create the paymentIntent, all of the payments are stored with a default amount of 500, set up in the Controller. I have to mention that after the success response from stripe, the current order should be stored in the database with user shipping details which are found in the first form and all the products ordered, stored in session. Let me show you for a better understanding.
This is the view (revieworder.blade.php) where I have a 2 forms, one with the user's shipping details, and the Stripe payment form, and a list of cart products from the session:
<ul class="list-group mb-3">
<?php $total = 0 ?>
@if(session('cart'))
@foreach(session('cart') as $id => $details)
<?php $total += $details['price'] * $details['quantity'] ?>
<li class="list-group-item d-flex justify-content-between lh-condensed">
<img src="../img/{{ $details['image'] }}" alt="{{ $details['name'] }}" width="60" height="60">
<div>
<h6 class="my-0">{{ $details['name'] }}</h6>
<small class="text-muted">{{ __('Quantity') }}: {{ $details['quantity'] }}</small><br>
<small class="text-muted">{{ __('Unit price') }}: {{ $details['price'] }} RON</small>
</div>
<span class="text-muted">{{ $details['price'] * $details['quantity'] }} RON</span>
</li>
@endforeach
@endif
<li class="list-group-item d-flex justify-content-between">
<span>Total (RON)</span>
<strong id="total">{{ $total.' RON' }}</strong>
</li>
</ul>
<form id="payment-form">
@csrf
<div id="card-element"><!--Stripe.js injects the Card Element--></div>
<button id="submit" class="submit-id">
<div class="spinner hidden" id="spinner"></div>
<span id="button-text">Pay now</span>
</button>
<p id="card-error" role="alert"></p>
<p class="result-message hidden">
</p>
</form>
<script>
//Stripe script
var stripe = Stripe("pk_test_XXX");
// The items the customer wants to buy
var purchase = {
items: [{id: "prod"}] //sessions cart
};
console.log(purchase);
var elements = stripe.elements();
var style = {
base: { //some styling },
invalid: {
fontFamily: 'Arial, sans-serif',
color: "#fa755a"
}
};
var card = elements.create("card", { style: style });
// Stripe injects an iframe into the DOM
card.mount("#card-element");
card.on("change", function (event) {
// Disable the Pay button if there are no card details in the Element
document.querySelector("button").disabled = event.empty;
document.querySelector("#card-error").textContent = event.error ? event.error.message : "";
});
// Disable the button until we have Stripe set up on the page
document.getElementsByClassName("submit-id").disabled = true;
$('#payment-form').submit(function(){
fetch("{{ url(app()->getLocale().'/revieworder') }}", {
method: "POST",
headers: {
"Content-Type": "application/json",
'X-CSRF-TOKEN': "{{ csrf_token() }}"
},
body: JSON.stringify(purchase)
})
.then(function(data) {
$('#payment-form').submit(function(event) {
event.preventDefault();
// Complete payment when the submit button is clicked
payWithCard(stripe, card, data.clientSecret);
});
});
// Calls stripe.confirmCardPayment
var payWithCard = function(stripe, card, clientSecret) {
loading(true);
stripe
.confirmCardPayment(clientSecret, {
payment_method: {
card: card
}
})
.then(function(result) {
if (result.error) {
// Show error to your customer
showError(result.error.message);
} else {
// The payment succeeded!
// The order should be stored in the database
orderComplete(result.paymentIntent.id);
}
});
};
// Shows a success message when the payment is complete
var orderComplete = function(paymentIntentId) {
loading(false);
document
.querySelector(".result-message a")
.setAttribute(
"href",
"https://dashboard.stripe.com/test/payments/" + paymentIntentId
);
document.querySelector(".result-message").classList.remove("hidden");
document.getElementsByClassName("submit-id").disabled = true;
};
// Show the customer the error from Stripe if their card fails to charge
var showError = function(errorMsgText) {
loading(false);
var errorMsg = document.querySelector("#card-error");
errorMsg.textContent = errorMsgText;
setTimeout(function() {
errorMsg.textContent = "";
}, 4000);
};
// Show a spinner on payment submission
var loading = function(isLoading) {
if (isLoading) {
// Disable the button and show a spinner
document.getElementsByClassName("submit-id").disabled = true;
document.querySelector("#spinner").classList.remove("hidden");
document.querySelector("#button-text").classList.add("hidden");
} else {
document.getElementsByClassName("submit-id").disabled = false;
document.querySelector("#spinner").classList.add("hidden");
document.querySelector("#button-text").classList.remove("hidden");
}
};
});
</script>
And then this is the controller which handles the secret client key and the paymentIntent (CheckoutController.php):
public function create(){
\Stripe\Stripe::setApiKey('sk_test_XXX');
header('Content-Type: application/json');
try {
$json_str = file_get_contents('php://input');
$json_obj = json_decode($json_str);
$paymentIntent = \Stripe\PaymentIntent::create([
'amount' => "500",
'currency' => 'ron',
]);
$output = [
'clientSecret' => $paymentIntent->client_secret,
];
echo json_encode($output);
} catch (Error $e) {
http_response_code(500);
echo json_encode(['error' => $e->getMessage()]);
}
}
So, one of the problems is that whenever I get to pay for an order, no matter what credit card number I pass, it always succeeds, and that is a major bug. The second one, I need to pass the total of the current order, otherwise all orders will get a total amount of 500, the default value. I tried to pass the session cart items to the fetch but it didn't work. Even though I cannot send all the items from the cart to the intent, at least the total price should correspond.
If I wasn't clear enough with anything, please let me know. I would really appreciate any piece of advice. Thank you !
