您可以使用类似的:(未测试,可能需要修改)


编辑:长寿,经常投票:D

您能告诉我们广播日期和时间是如何保存在数据库中的吗?这可能会改变您的查询方式。此外,在WP_查询的上下文中可能不可能执行此操作-您可能必须直接查询数据库才能完成此操作。@MikelBitson感谢您的回复,我已经从插件中添加了代码。您可以打开数据库,打开usermeta表,并搜索像“%broadcast_date%”这样的键吗?这将向您显示保存在数据库中的meta_值,通过这种方式,我们可以查看如何查询,因为我们将知道这些值保存为的格式。_broadcast_date存储为YYYY-MM-DD,_broadcast_time为HH:MMIt适用于日期,但不适用于时间:(我在时间查询中尝试将小h改为大写h,因为时间是以24小时格式存储的,但这取消了日期查询,只显示时间晚于当前时间的帖子。它似乎接近我要查找的内容,但它运行的是
query1或query2
而不是
query1和query2
Hey@user28419我为AND关系和24小时时间编辑了我的帖子-如果这仍然不起作用,我们将需要进行一些调试。忽略我的第一条评论,将H改为大写似乎实际上并没有改变查询,我认为时间查询根本不起作用,在日期和ti上将元查询改为AND操作我是一个问题。例如,如果是14:00,明天03:00的节目就不会出现。这可能会有所帮助
