Undefined index stripeToken - symfony

Question

I have a stripe checkout error in my symfony project. Here is my view that uses checkout by default :
<form action="" method="POST">
<script
src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="pk_test_C9N5xzeBHyGplmZwpsbyciS6"
data-amount="9999"
data-name="Demo Site"
data-description="Widget"
data-image="https://stripe.com/img/documentation/checkout/marketplace.png"
data-locale="auto"
data-zip-code="true"
data-currency="eur">
</script>
</form>
The method of my controller:
public function paiementAction(Request $request)
{
\Stripe\Stripe::setApiKey("sk_test_5W9Z1CdBKN2G46sTa2O5KI3T");
$token = $_POST['stripeToken'];
try {
$charge = \Stripe\Charge::create(array(
"amount" => 1000, // Amount in cents
"currency" => "eur",
"source" => $token,
"description" => "Example charge"
));
return $this->redirectToRoute("chk38_platform_confirmation");
} catch (\Stripe\Error\Card $e) {
// The card has been declined
return $this->redirectToRoute("chk38_platform_commande");
}
}`
Error Symfony
Thank you for your help

Answer 1

This issue of $_POST['stripeToken'] not being populated generally occurs when your code isn't creating a Token object via Stripe Checkout prior to running this bit of code.
I would suggest that you check your Stripe account's API logs (https://dashboard.stripe.com/test/logs/overview) and ensure that you are in fact correctly creating a Token object via Stripe Checkout prior to calling this create Charge snippet.
You may also want to read through their Checkout PHP tutorial (https://stripe.com/docs/checkout/php), to get a better understanding of how all of the pieces fit together. If you still have issues after all that, you may want to write in to their support staff via https://support.stripe.com/email since you probably don't want to discuss private account specific things in public.

Answer 2

This is a quick finding I just experienced. If you're using the default <form action="/directory" method="POST"> ... </form> from this stripe example page with your own endpoint make sure to specify down to the index.php file inside the directory folder.
I was getting an odd error where the token was being created but I would get directed to the PHP endpoint and it wasn't a POST event. I had an index.php file in /directory/ and I had to write the complete path not just up to /directory eg. /directory/index.php. Then it worked as expected.

Answer 3

I want to confirm and extend what subalublub said, in that the endpoint can simply be "/charge/" without having to use index.php there.
I ran into this issue and just using "/charge" was not passing in the $_POST values, but when changing to "/charge/" the index.php file inside that folder worked correctly.
Hope this helps someone.
