如何在PayPal快速结账中禁用“买家注意”？

I've got a problem integrating PayPal Express Checkout. I want to disable the possibility to add a note to the buyer during the checkout process.

• I'm using the PHP SOAP SDK (merchant-php-1.1.93_0.zip).
• service.EndPoint targets to https://api.sandbox.paypal.com/2.0/.

• In the first step of the order, where I make the SetExpressCheckout.. call I set the following value:

  $SetECReqDetails->AllowNote = 0;

$SetEcReqDetails is the instance of \SetExpressCheckoutRequestDetailsType. But the customer is still able the enter a note at the PayPal site.

You're setting AllowNote to 0, not "0".

var_dump(0 == null) //outputs: boolean true

Code in the PayPalAPIInterfaceService, line 2436, has the following:

if($this->AllowNote != null) {
    //prop is not a collection
    //prop not complex
    //prop is not value

So basically, you are not defining AllowNote.

I have verified that with the SDK you are using, currently offered on x.com for EC, your code does not work, and the following does work:

$setECReqDetails->AllowNote = "0";
