超薄支付控制器

Question

I followed a serie on creating a shopping cart on codecourse - and it was just what I was looking for.

In the series the payment happens on creating the order - but now my client says that they don't want the payment on creating order - first when they have processed the order - they want to send an email with payment or an link to a payment site.

I thought no big deal - just move the BraintreePayment par out of the create class - create a new class called payment and thats that - but no - so now I am stuck.

I am using swiftmailer to send the mail with the link and that works fine - but the payment part fails.

I am new to this MVC / Slim thing - so please can someone help me in the right direction.

The error it throws say:

Type: TypeError Message: Argument 1 passed to Cart\Events\OrderWasCreated::__construct() must be an instance of Cart\Models\Order, integer given, called in /Applications/AMPPS/www/testshop.dev/cart/app/Controllers/OrderController.php on line 160 File: /Applications/AMPPS/www/testshop.dev/cart/app/Events/OrderWasCreated.php Line: 17

My ordercontroller with the payment class - looks like this:

<?php

The error occures on line 160:

$event = new \Cart\Events\OrderWasCreated($order, $this->basket);

because you invoke Cart\Events\OrderWasCreated constructor, which requires instance of Cart\Models\Order class as first argument. Instead your first argument ($order) is integer.

Now latest assignment of $order is on line 147:

$order = $customer->orders()->update([
    'paid' => true,
]);

I'll have a guess and say that this is an operation that returns integer as result (be that a simple 1/0 success/fauilure or the id of the order being updated). Are you sure that you need that? Asking because:

• You are assigning $order a value on line 138:

  $order = $order->with('address', 'products')->where('id', $slug)->first();

• And you're passing $order as an argument to the OrderController::payment.

So, my guess is: you want to remove lines 138 and 147.
