英文:
Convert ISOdate to phpdate for ACF custom field query
问题
我已经构建了一个自定义的海狸生成器（WordPress）模块。我正在通过Ajax获取帖子。我需要基于ACF自定义字段日期查询帖子。
我以ISO8601格式发布日期（例如2013-12-01T00:00:00-05:00）。在服务器端，我获取开始和结束日期。我将它们转换为ACF查询所需的格式 https://www.advancedcustomfields.com/resources/date-picker/
$start_date = date('Ymd', strtotime($_POST['start']));$end_date = date('Ymd', strtotime($_POST['end']));
我运行查询，但没有得到任何结果。我将字符串打印出来，它们看起来是正确的。
如果我按照ACF文档中的示例设置日期 - 它可以工作（下面的代码）。所以我一定是错误地转换了ISO日期 $_POST['start']。我如何转换ISODATE，以便在查询中使用？
function get_ajax_event_calendar_posts() {$today = date('Ymd'); // 这个可以工作...$args = array('post_type' => array('event'),'meta_query' => array(array('key' => 'start_date','compare' => '<=','value' => $today,),array('key' => 'end_date','compare' => '>=','value' => $today,)),'post_status' => array('publish'),'posts_per_page' => 100,'nopaging' => true,'order' => 'DESC','orderby' => 'date');// 查询$ajaxposts = get_posts( $args );//... 等等}

.... 日期并不是问题。我才是问题... 将比较条件反过来，一切都正常工作...

I've built a custom beaver builder (wordpress) module. I'm fetching posts via Ajax. I need to query posts based off an ACF custom field date.
I am posting the date in ISO8601 format (eg 2013-12-01T00:00:00-05:00). Server side, I grab the start and end. I convert them into the format needed for the ACF query https://www.advancedcustomfields.com/resources/date-picker/
$start_date = date('Ymd', strtotime($_POST['start']));$end_date = date('Ymd', strtotime($_POST['end']));
I run the query, and get nothing. I echo the string out, and they look correct.
If I set the date as per the example in the ACF docs - it works (code below). So I must be converting the ISOdate $_POST['start'] incorrectly. How do I convert the ISODATE so that is it something that I can use in the query?
function get_ajax_event_calendar_posts() {$today = date('Ymd'); // this works...$args = array('post_type' => array('event'),'meta_query' => array(array('key' => 'start_date','compare' => '<=','value' => $today,),array('key' => 'end_date','compare' => '>=','value' => $today,)),'post_status' => array('publish'),'posts_per_page' => 100,'nopaging' => true,'order' => 'DESC','orderby' => 'date');// The Query$ajaxposts = get_posts( $args );//... etc}
** edit **
.... the date stuff wasn't the problem. I was the problem... switched my compares round the right way and all works...

你没有说明实际需要存储数据的格式，但你提到了 date('Ymd') 可行。无论如何，可以使用 DateTime 类：
<?php$x = new DateTime('2013-12-01T00:00:00-05:00');echo $x->format('d/m/Y H:i:s') . "\n"; // 01/12/2013 00:00:00echo $x->format('dmY') . "\n"; // 01122013
这里是日期格式的链接：https://www.php.net/manual/en/function.date.php
英文:
You haven't said what format you actually need to store the data, however you did say date('Ymd') works. Either way, use the DateTime class:
<?php$x = new DateTime('2013-12-01T00:00:00-05:00');echo $x->format('d/m/Y H:i:s') . "\n"; // 01/12/2013 00:00:00echo $x->format('dmY') . "\n"; // 01122013
Here are the date formats https://www.php.net/manual/en/function.date.php
