Question

我想在我的网站上添加一些统计数据，我想每个月显示我的收入，当汽车从租金返回时（当天：预期返回月份）。我想计算每月的收入总额（租金价格）（预计退货日期），有人可以帮助我，我该怎么做？ enter image description here

这是View / Location / admin_index.ctp：

有人可以帮帮我吗？

我相信您应该通过使用日期/时间函数执行SUM()和COUNT()查询来统计控制器中的统计信息（除非您每页需要它）。有很多非常强大的功能可以帮助您计算日期间隔。

（我假设您使用的是mysql或类似的东西。）

请添加一些相关的DB结构，这样我就可以帮助您构建查询。
