Criando faturas transparentes com PayPal

assets/js/javascript.js

No nosso javascript vamos enviar a função getCheckout para o escopo global:

win.checkout=getCheckout;

checkout.php

Na nossa view checkout vamos executar a função getCheckout que enviamos para o escopo global:

<script>checkout();</script>

controllers/ControllerInvoice.php

No controller da fatura vamos percorrer a session products e ir adicionando os itens do carrinho:

<?php
require_once ('../config/config.php');
require_once ('../class/ClassPayment.php');
require_once ('../class/ClassCarrinho.php');
$objPayment=new ClassPayment();
$objCarrinho=new ClassCarrinho();

$items="";
$i=1;
foreach ($_SESSION['products'] as $products){
    $cont=count($_SESSION['products']);
    $comma=($i >= $cont)?'':',';
    $items.='
    {
        "name": "'.$products['name'].'",
        "description": "'.$products['name'].'",
        "quantity": "'.$products['quantity'].'",
        "price": "'.$products['price'].'",
        "tax": "0.00",
        "sku": "product'.$products['id'].'",
        "currency": "BRL"
      }'.$comma.'';
    $i++;
}

$data='{
  "intent": "sale",

    "payment_method": "paypal"
  },
  "transactions": [{

    },

    }
  }],
  "redirect_urls": {
    "return_url": "https://example.com/return",
    "cancel_url": "https://example.com/cancel"
  }
}';
//echo "<pre>",print_r($data),"</pre>";
echo $objPayment->invoice($data);
