To handle card declined errors on subscription creation, you can catch the Stripe\Exception\CardException exception that is thrown when a card is declined. You can then handle the error appropriately, such as displaying an error message to the user and preventing the subscription from being created.
Here's an example of how you can catch the exception in a Laravel controller method:
use Stripe\Exception\CardException;
public function subscribe(Request $request)
{
try {
$user = $request->user();
$user->newSubscription('default', 'monthly')->create($request->stripeToken);
// Subscription created successfully
return redirect()->back()->with('success', 'Subscription created successfully.');
} catch (CardException $e) {
// Card was declined
$message = $e->getMessage();
return redirect()->back()->with('error', $message);
} catch (\Exception $e) {
// Other error occurred
$message = $e->getMessage();
return redirect()->back()->with('error', $message);
}
}
In this example, we're using the newSubscription method provided by Laravel Cashier to create a new subscription for the user. We're passing in the Stripe token that was generated by the Stripe.js library when the user submitted their payment information.
If a CardException is thrown, we catch it and display an error message to the user. If any other exception is thrown, we catch it and display a generic error message.
By handling the CardException in this way, we can prevent subscriptions from being created when a user's card is declined.
