Paypal IPN脚本：在我的网站上创建一个php，它接收确认的支付消息并插入到wordpress db中

Question

There are two parts to this question, so I'm going to pubish it as two separate questions. The first one deals with interfacing with IPN and is this:

I need to create a simple .php script that can interface with Paypal's IPN system everytime I receive a confirmed payment for a given product.

The script will then install the user into my wordpress user's database as a "member" (which is a custom role I've defined) using their email address as their username and the paypal transaction id as their password.

I'm doing it this way because I can easily enter all the people who have purchased prior to this, into the database without having to generate random passwords for everyone.

Any help with interfacing with IPN?

The second question will be much easier and that's how to use the IPN data (firstname, lastname, email address and transaction id) to enter the user into the wordpress member database.

Just use Micah Carrick Paypal IPN Class. It have validate_ipn() method that can be used to protect a block of code where you want to put update script:

if ( $paypal->validate_ipn() )
{
  $ipn_data = $paypal->ipn_data;
  $invoice = $ipndata['invoice'];
  //do update here, based on invoice
  //...
}
