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...

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 00:00:00
echo $x->format('dmY') . "\n";     // 01122013

Here are the date formats https://www.php.net/manual/en/function.date.php
