Payment failed but order is Placed in Laravel with Stripe - laravel

Question

I have integrated stripe payment in flutter app but After payment got failed even then order placed in Laravel database so please check, what I have done wrong.
Please check at save method, May be I am wrong and can't validate purchase response.
payment controller
public function makePayment(Request $request)
{
try{
$data = $request->input('cartItems');
$cartItems = json_decode($data, true);
$orderData = $request->input('order');
$selectPaymentOption = json_decode($orderData, true);
$totalAmount = 0.0;
foreach ($cartItems as $cartItem){
$order = new Order();
$order->order_date = Carbon::now()->toDateString();
$order->product_id = $cartItem['productId'];
$order->payment_type = $selectPaymentOption['paymentType'];
$order->user_id = $request->input('userId');
$order->quantity = $cartItem['productQuantity'];
$order->amount = ($cartItem['productPrice'] - $cartItem['productDiscount']);
$totalAmount+= $order->amount * $order->quantity;
$order->save();
}
if($selectPaymentOption['paymentType'] == 'Card'){
\Stripe\Stripe::setApiKey('sk_test_hJUgYYzeXtitxxxx71lK8nE00MELJJS8c');
$token = \Stripe\Token::create([
'card' => [
'number' => $request->input('cardNumber'),
'exp_month' => $request->input('expiryMonth'),
'exp_year' => $request->input('expiryYear'),
'cvc' => $request->input('cvcNumber')
]
]);
$charge = \Stripe\Charge::create([
'amount' => $totalAmount * 100,
'currency' => 'inr',
'source' => $token,
'receipt_email' => $request->input('email'),
]);
}
return response(['result' => true]);
} catch (\Exception $exception){
return response(['result' => $exception]);
}
}
and my Flutter's Post request is here.
I want to POST _makePayment method after complete payment successful.
void _makePayment(BuildContext context, Payment payment) async {
PaymentService _paymentService = PaymentService();
var paymentData = await _paymentService.makePayment(payment);
var result = json.decode(paymentData.body);
print(paymentData);
CartService _cartService = CartService();
this.widget.cartItems!.forEach((cartItem) {
_cartService.makeTheCartEmpty();
});
if (result['result'] == true) {
_showPaymentSuccessMessage(context);
Timer(Duration(seconds: 4), () {
Navigator.pop(context);
Navigator.push(
context, MaterialPageRoute(builder: (context) => HomeScreen()));
});
}
}

Referring to my comment above, this is the rough solution I suggested in your controller you have to switch the logic
public function makePayment(Request $request)
{
try{
$data = $request->input('cartItems');
$cartItems = json_decode($data, true);
$orderData = $request->input('order');
$selectPaymentOption = json_decode($orderData, true);
##Change your frontend logic to pass total amount as variable
$totalAmount = $request->totalAmount;
if($selectPaymentOption['paymentType'] == 'Card'){
##Never have any sk or pk in your controller, switch this to config('common.sk_test')
\Stripe\Stripe::setApiKey(config('common.sk_test'));
$token = \Stripe\Token::create([
'card' => [
'number' => $request->input('cardNumber'),
'exp_month' => $request->input('expiryMonth'),
'exp_year' => $request->input('expiryYear'),
'cvc' => $request->input('cvcNumber')
]
]);
$charge = \Stripe\Charge::create([
'amount' => $totalAmount * 100,
'currency' => 'inr',
'source' => $token,
'receipt_email' => $request->input('email'),
]);
}
##After the stripe transaction is finished you can foreach your cart and do what you need to your database
foreach ($cartItems as $cartItem){
$order = new Order();
$order->order_date = Carbon::now()->toDateString();
$order->product_id = $cartItem['productId'];
$order->payment_type = $selectPaymentOption['paymentType'];
$order->user_id = $request->input('userId');
$order->quantity = $cartItem['productQuantity'];
$order->amount = ($cartItem['productPrice'] - $cartItem['productDiscount']);
$order->save();
}
return response(['result' => true]);
} catch (\Exception $exception){
return response(['result' => $exception]);
}
}
For the config('common.sk_test') part of my answer, in you config folder you can create a new file where you have you custom app variables, so create a file for instance common.php and 'sk_test' that takes its value from you .env file
