Я пробовал этот скрипт с песочницей в первый раз, и ВСЕ работал нормально! Теперь я попробовал живую версию, и у меня мало ошибок: во-первых, после оплаты, потому что я не перенаправлялся. Но я видел, как его решить, и теперь отлично работает. Во-вторых: после оплаты я перенаправляюсь к своему слушателю IPN, но я не знаю, почему я теряю базу данных, даже если получаю деньги. Это мой код. Это почти Paypal IPN от github. Есть ли у вас какие-либо идеи ?PayPal платежи IPN
