如何将PayPal Classic Payment表单转换为PayPal REST API PHP应用程序？

Question

The following is the simplest PayPal interface form:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" /> 
  <input type="hidden" name="cmd" value="_xclick" /> 
  <input type="hidden" name="business" value="[e-mail]" /> 
  <input type="hidden" name="item_name" value="Purchase at the Virtual Store" /> 
  <input type="hidden" name="item_number" value="Organic-001" />
  <input type="hidden" name="amount" value="17.4" /> 
  <input type="hidden" name="currency_code" value="EUR" /> 
  <input type="hidden" name="notify_url" value="http://www.example.com/paypalnotify.php" /> 
  <input type="submit" name="submit" value="Pay now By PayPal" />
</form>

This form is specific to a PayPal premier business account and a given amount to pay, with following key parameters:

1. business=[e-mail].
2. amount=17.4EUR.
3. currency_code=EUR or USD.
4. notify_url as the callback for PayPal.com as it ends.

By clicking on the [submit] button, it perfoms this:

1. It redirects the customer to the paypal.com site.
2. The user will login into her/his PayPal account, and validate the payment.
3. The PayPal site will call the paypalnotify.php like a callback, passes information indicating if the payment has suceeded, cancelled, or not valid...

Now in the new interface using PalPal REST API, using PHP development kit, how one has to proceed to accomplish the payment ?

There are a few options. Start by looking at the code in these files:

Obviously they don't have any interactive forms, but they show the general process. Dig in and work through creating your code. Then when you hit problems, open a new question with the specific issues. StackOverflow is not for "how do I" type questions. https://stackoverflow.com/help/on-topic
