创建每日列表项目计数 [英] Create a daily list item count

问题描述

 您好，

我正在尝试创建一个只允许每天创建一定数量的新项目的列表表单。一种方法是在列表中创建项目的每日索引，然后创建一个不允许索引大于X的预保存验证。

I'm trying to create a list form that only allows to create a certain number of new items per day. One approach would be to create a daily index of items in the list and then create a pre-save validation that does not allow an index greater than X.

我坚持创建每日指数。能帮忙吗？

I am stuck at creating the daily index. Can you please help?

提前谢谢！

推荐答案

Hi Mircea，

Hi Mircea,

您可以参考"tom.vangaever"的建议;： 

You can refer to the suggestion by "tom.vangaever": 

You can loop by using a foreach on the List.Items and use the created field of the item, but that is not really best practice.

try to use a specfic SPQuery that returns only the items that are created the same date that the new event is added and check the amount of items this query results...

参考（尽管该文章用于日历列表，但对您也很有用）：
