Question

我正在做我的毕业设计电子商务网站http://www.fieldhockey-world.co.uk，我希望用户能够通过PayPal查看他们以前的订单。我设法集成PayPal，但我尝试从用户表创建 ForeignKey 到交易表但我无法获取数据，因为用户被重定向到PayPal网站购买商品。我的数据库表如下： 交易表

id int（11） PK
product_id_array varchar（255）
payer_email varchar（255）
first_name varchar（255）
last_name varchar（255）
payment_date varchar（255）
mc_gross varchar（255）
payment_currency varchar（255）
txn_id varchar（255） UNIQUE
receiver_email varchar（255）
payment_type varchar（255）
payment_status varchar（255）
txn_type varchar（255）
payer_status varchar（255）
address_street varchar（255）
address_city varchar（255）
address_state varchar（255）
address_zip varchar（255）
address_country varchar（255）
address_status varchar（255）
notify_version varchar（255）
verify_sign varchar（255）
payer_id varchar（255）
mc_currency varchar（255）
mc_fee varchar（255）

**

USERS TABLE

user_id int（11） PK
用户名 varchar（32）
密码 varchar（32）
first_name varchar（32）
last_name varchar（32）
电子邮件 varchar（80） UNIQUE email_code varchar（32）
有效 int（11）
type int（11 ** ）**
date_of_birth 日期
street_address varchar（80）
city varchar（80）
post_code varchar（6）

如果您有任何想法，请告诉我。谢谢！
