问题描述
您好！
我在DB上有一些横幅。每个横幅都有参数：
Hello!
I have some banners at DB. Every banners has params:
position //1 - top banners, 2 - right banners, 3 - left banners
id
showes //2000 Common number of showing banners
showed //A number of showing banner for current user, default = 3
我尝试制作系统，这将显示横幅对于当前用户不超过2次。
例如，我进入网站，我看到顶部位置1横幅，右侧1横幅和左侧1横幅。
当我重新加载页面时，我会这样做：
1）将检查位置1的公共横幅数是否大于0且参数显示> 0，然后在1减去（将为2）减少横幅的显示参数。
此操作必须为每个横幅做。如果显示== 0需要从位置显示任何横幅并检查相同（项目 1 ）
现在我的代码不好，可以由你帮助我彻底完成它
I try to make system, that will shows banners for current user not more that 2 times.
For example, i entered to site, and i see at top position 1 banner, at right side 1 banner and at left 1 banner.
When i make reload page i will do:
1) Will check if common number of banner from position 1 is larger that 0 and parametr showed > 0, then to reduce "showed" parametr for banner on 1 minus (will be 2).
And this operation must do for each banners. If "showed" == 0 need show any banner from position and check it same (item 1)
Now i have a bad code, may by you could help me make it thoroughly
