درخواست راهنمایی برای یک تغییر کوچیک در یکی از پلاگین های وردپرس

سلام
من این پلاگین را روی وردپرس نصب کردم
http://www.tipsandtricks-hq.com/word...art-plugin-768
این پلاگین اطلاعات سفارش را به سبد خرید منقل می کند و با کلیک روی پرداخت ما را به سایت پی پال منتقل می کند
می خوام این اطلاعات را روی فرم دیگری منتقل کنم و آنها را بعد از تایید به ایمیل مشخص شده ارسال کنم
چند تا مشکل دارم
اول اینکه اطلاعاتی که از سبد خرید به پی پال منتقل میشه را چطور مشخص کنم ؟
می خوام متغییرش رو پیدا کنم البته این کد ها خیلی سخته و من فقط یک اشنایی کلی باهاشون دارم
دوم اینکه چطور این اطلاعات را به فرم دیگر منتقل کنم ؟
ممنون
