如何自定义PayPal的结账页面（PayPal-PHP-SDK）

Question

I am working with the PayPal-PHP-SDK as suggested in the Developer Docs. I am running this code currently:

http://paypal.github.io/PayPal-PHP-SDK/

I simply want to change the Brand Name and add a Logo, but I don't know how to achieve this.

Since PayPal updated their Design the Design changes you can make in the profile Settings wont work anymore.

To change the Design, you need to create a WebProfile first:

    // Create the WebProfile
    $presentation = new Presentation();
    $presentation->setLogoImage("http://www.yeowza.com/favico.ico")
        ->setBrandName("YeowZa! Paypal")
        ->setLocaleCode("US");
    $inputFields = new InputFields();
    $inputFields->setAllowNote(true)
        ->setNoShipping(1)
        ->setAddressOverride(0);
    $webProfile = new WebProfile();
    $webProfile->setName("YeowZa! T-Shirt Shop" . uniqid())
        ->setPresentation($presentation)
        ->setInputFields($inputFields);
    try {
        $createdProfile = $webProfile->create($paypal);
        $createdProfileID = json_decode($createdProfile);
        $profileid = $createdProfileID->id;
    } catch(PayPal\Exception\PayPalConnectionException $pce) {
        echo '<pre>',print_r(json_decode($pce->getData())),"</pre>";
        exit;
    }

The ID of the created Profile is been stored in $profileid.This ID needs to be set via. setExperienceProfileId($profileid) if you create the payment.

        // Create the Payment       
    $product = $_POST['product'];
    $price = 4;
    $shipping  = 2;
    $total = $price + $shipping;

    $payer = new Payer(); 
    $payer->setPaymentMethod("paypal");

    $item1 = new Item();
    $item1->setName('Ground Coffee 40 oz') ->setCurrency('EUR') ->setQuantity(1) ->setSku("123123")->setPrice(6.5); // Similar to `item_number` in Classic API 
    $item2 = new Item();
    $item2->setName('Granola bars') ->setCurrency('EUR') ->setQuantity(1) ->setSku("321321")->setPrice(1.5); // Similar to `item_number` in Classic API  
    $itemList = new ItemList(); 
    $itemList->setItems(array($item1, $item2));

    $details = new Details(); 
    $details->setShipping(1.2) ->setTax(1.3) ->setSubtotal(8);

    $amount = new Amount();
    $amount->setCurrency("EUR") ->setTotal(10.5) ->setDetails($details);

    $transaction = new Transaction();
    $transaction->setAmount($amount)->setItemList($itemList)->setDescription("Payment description")->setInvoiceNumber(uniqid());

    $baseUrl = "http://localhost/abiunity/test.php"; 
    $redirectUrls = new RedirectUrls(); 
    $redirectUrls->setReturnUrl($baseUrl."?success=true")->setCancelUrl($baseUrl."?success=false");

    $payment = new Payment(); 
    $payment->setExperienceProfileId($profileid)->setIntent("sale") ->setPayer($payer) ->setRedirectUrls($redirectUrls) ->setTransactions(array($transaction));
    //$request = clone $payment;

    try {
        $payment->create($paypal);
        $approvalUrl = $payment->getApprovalLink();
        header("Location:".$approvalUrl);
        exit;
    } catch(PayPal\Exception\PayPalConnectionException $pce) {
        echo '<pre>',print_r(json_decode($pce->getData())),"</pre>";
        exit;
    }

I hope this helps someone and saves a little bit of time :)
