Php 我想在“选择”下拉列表中动态禁用下两个值
我正在制作活动日历，当一个用户预订了一个时间时，其他用户将无法选择该时间加上下两个时间段 就像我们有3:00 AM、3:30 AM、4:00 AM，直到24小时，如果用户选择3:00 AM，那么3:30 AM和4:00 AM也将被禁用 我已禁用凌晨3:00，但我没有找到一种方法来动态禁用凌晨3:30和凌晨4:00插槽Php 我想在“选择”下拉列表中动态禁用下两个值,php,wordpress,Php,Wordpress,我正在制作活动日历，当一个用户预订了一个时间时，其他用户将无法选择该时间加上下两个时间段 就像我们有3:00 AM、3:30 AM、4:00 AM，直到24小时，如果用户选择3:00 AM，那么3:30 AM和4:00 AM也将被禁用 我已禁用凌晨3:00，但我没有找到一种方法来动态禁用凌晨3:30和凌晨4:00插槽 $date = '20190713'; $taken_slots = array(); $bookings_qry = $wpdb->get_results("SELE

在上面的代码中，我从wp_时间表中获取时间，并从数据库中匹配wp_booked_时间表中的预定值。现在请帮助我如何禁用下两个值。任何帮助都将不胜感激。提前感谢操纵时间（以及迭代时间间隔）的最佳方法是使用本机PHP DateTime、DateInterval和DatePeriod。您需要检查当前单位间隔是否与现有约会重叠。下一步是检查所选的时段是否足够长，以满足所选/所需的单位数量。还有进一步定制的空间，但这应该（我希望）为您指明了正确的方向

你能进一步解释一下吗。我不明白在我的情况下它将如何工作？@SiteSoft在我继续之前，请阅读代码注释。另外，请您复制粘贴代码，看看它是否真的能满足您的需要？请您进一步解释一下。我不明白在我的情况下它将如何工作？@SiteSoft在我继续之前，请阅读代码注释。您也可以复制粘贴代码，看看它是否真的能满足您的需要吗？
