How to store user details after paypal payment approval? - php

Question

I'm building an online courses website, where students can buy a course via PayPal. The payment process is working successfully, But I'm confused on where or how to store course and user data after PayPal Payment Approval.
I have a users table, courses table and pivot table: course_students where I store the id of the course and the id of the student:
-------------
course_students
--------------
student_id course_id
1 2
----------
This is PayPalService Class:
class PayPalService
{
use ConsumesExternalServices;
protected $baseUri;
protected $clientId;
protected $clientSecret;
public function __construct()
{
$this->baseUri = config('services.paypal.base_uri');
$this->clientId = config('services.paypal.client_id');
$this->clientSecret = config('services.paypal.client_secret');
}
public function resolveAuthorization(&$queryParams, &$formParams, &$headers)
{
$headers['Authorization'] = $this->resolveAccessToken();
}
public function decodeResponse($response)
{
return json_decode($response);
}
public function resolveAccessToken()
{
$credentials = base64_encode("{$this->clientId}:{$this->clientSecret}");
return "Basic {$credentials}";
}
public function handlePayment(Request $request)
{
$order = $this->createOrder($request->value, $request->currency);

$approve = $orderLinks->where('rel', 'approve')->first();
session()->put('approvalId', $order->id);
return redirect($approve->href);
}
public function handleApproval()
{

$approvalId = session()->get('approvalId');
$payment = $this->capturePayment($approvalId);
$name = $payment->payer->name->given_name;
$payment = $payment->purchase_units[0]->payments->captures[0]->amount;
$amount = $payment->value;
$currency = $payment->currency_code;
return redirect()
->route('success')
->with('payment', "Thanks, {$name}. We received your {$amount}{$currency} payment.");
}
// $errorMessage = 'We cannot capture the payment. Try again, please';
return redirect()
->route('paymentform')

Answer 1

In your payment controller you can save you the course information in session. After payment when user will redirect, save the information to your desired database table..
//save course info or other info
session()->put('courseInfo', [your data]);
your controller function:
/**
* implment Payemnt process
*
* #param Request $request
*/
public function pay(Request $request)
{
// dd($request->all());
$rules = [
'value' => ['required', 'numeric', 'min:5'],
'currency' => ['required', 'exists:currencies,iso'],
'payment_platform' => ['required', 'exists:payment_platforms,id'],
];
$request->validate($rules);
$paymentPlatform = $this->paymentPlatformResolver
->resolveService($request->payment_platform);
session()->put('paymentPlatformId', $request->payment_platform);
//save course info or other info
session()->put('courseInfo', [your data]);
return $paymentPlatform->handlePayment($request);
}
you another function: approval() call another function $paymentPlatform->handleApproval(); inside of it after payment done.
Go to handleApproval() function and hopefully you will find there user account creation codes. Now get the session value session()->get('courseInfo') and save in your desired table.
