求助:购物时订单号的传值和订单插入问题
写了一个购物车 将购买信息存入SESSION 进入结算 页面 1
用SESSION 显示信息 并有input 要求输入发货信息
点击提交 将输入的信息插入数据库 将生成的订单号传入 页面 2
在 页面2 通过得到的订单号 查询数据库且输出
现在的问题是 在页面1不能执行插入数据库的操作 只会跳转
请教各位高手 或者有更号的处理方法也可以

------解决方案--------------------
没看到表单,你用什么提交的?
如果是 js,至少也应贴出代码
------解决方案--------------------
在页面1不能执行插入数据库的操作 只会跳转
我不明白,go('pay.php'); 是跳转吧? 那么 $in_ord=mysql_query($ding); 值就是 true啊。应该说插入成功了已经
------解决方案--------------------
没看到input submit按钮,那么表单数据也就不会提交到 jiesuan.php。
pay.php 也就查询不到数据
------解决方案--------------------
先提交到插入页面,完成后,从插入页面直接再跳转到pay.php不就可以了?

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
