To make their own blog sustainable development, it is necessary to be able to feed themselves.

Some time ago, to do a donor wordpress plugin WP-DONATORS, can support PAYPAL donation and multi-currency exchange rate for automatic conversion. And other donations button, it also has a background with PAYPAL API real-time communication, the return of payments data, and then the donor specified connection with the advertisements on the "donor cloud" showing up.

Followed by more background and support for the currency. First, the renminbi, paypal.com does not support the yuan, of course, the thought of "pay-Bao", but "pay-bao" to communicate their staff not to provide personal donation function.

Discovered the "PayPal" (that is paypal China) recently in October, he updated the cost of RMB policy, free of charge. Should pay attention to the "PayPal" paypal is specific to China's renminbi business, with Universal paypal.com account (foreign currency), so you must specifically for the "PayPal" registered account. Registration, "PayPal"

They just use the same paypal API so easy to add features yuan. When used in the background as long as the words "PayPal" account opened on the RMB. When the donor to use RMB for payment, the amount went to "PayPal" account, go to other currencies paypal account. You can use the credit card paypal.com to open foreign currency accounts to support multi-currency

Multi-currency variables: For non-US dollar payment, IPN will add the following multi-currency variables, mc_gross and mc_fee
mc_gross: transaction fees deducted before the payment is received to pay the full amount of currency.
mc_fee: payment and paid currency-related transaction costs. Payment_fee similar to the variable function of the variables (such as the amount to be paid, the non-variable).
For rental IPN, such as registration, cancellation, modification, and the failure of EOT, mc_currency is the currency rates rather than monetary payment.
