This is a easy method to group custom posts by a date advanced custom field. I’m also going to sort by the date meta type.
<?php
$args = array(
'post_type' => 'calendar-event',
'posts_per_page' => -1,
'meta_key' => 'ce_start_date',
'meta_type' => 'DATE',
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_query' => array(
array(
'key' => 'ce_start_date',
'value' => date('Y-m-d'),
'compare' => '>=',
),
),
);
$the_query = new WP_Query($args);
$groupDate = null;
if ($the_query->have_posts()) {
while ($the_query->have_posts()) {
$the_query->the_post();
$startDate = DateTime::createFromFormat('Y-m-d', get_field('ce_start_date'));
if ($startDate->format('m') !== $groupDate) {
if ($groupDate !== null) {
echo "</section>";
}
$groupDate = $startDate->format('m'); ?>
<section date-group="<?php print $startDate->format('m'); ?>">
<h2><?php print $startDate->format('F') ." ". $startDate->format('Y'); ?></h2>
<?php } ?>
<!-- post data -->
<?php
}
} else {
// no posts found
}
/* Restore original Post Data */
wp_reset_postdata();
?>
</section>
