使用cookie做购物车的有关问题
使用cookie做购物车的问题
使用cookie做购物车的话，不是使用当前的cookie，然后再加入相关的产品信息到数据库吗
可是如果用cookie的话，第一次是加不进去的，需要2次才可以啊，有没有好的解决方案啊。
------解决方案--------------------
建议这样 在客户端 用js写cookie
然后服务端获取 就存了。
如果你在服务端 写cookie
那么就别再用$_COOKIE变量 这样的确是获取不到的
而是用你最开始的变量
------解决方案--------------------
加不进去是什么意思，我现在就是在用cookie做购物车，不过全部是前端操作。
如果你的意思是添加cookie的同时还要往后台写数据，那么只能用ajax提交数据。
------解决方案--------------------
加2次才进去，建议贴代码
------解决方案--------------------
可以用JS自带的setinterval()解决这个问题，隔多久执行一次
