PHP-code for displaying ACF-fields on Wordpress post? - php

Question

I have a PHP-code snippet array showing a list of ACF-field values from posts. I would like to use that code on a single post and only show the ACF-values from the current post. So it´s no longer a list. I still need the date filtering.
What do I have to change for it to work like I intend?
<?php
$today = current_time('Ymd');
$args = array(
'post_type' => 'post',
'posts_per_page' => '20',
'meta_key' => 'kalenderdag',
'order' => 'ASC',
'orderby' => 'meta_value',
'meta_query' => array(
array(
'key' => 'kalenderdag',
'compare' => '>=',
'value' => $today,
'type' => 'DATE'
),
),
);
$children = new WP_Query($args);
?>
<?php if ($children->have_posts()) : ?>
<?php while ($children->have_posts()) : $children->the_post(); $fields = (object) get_fields(); ?>
<div class="event row">
<div class="event-logo col-sm-4">
<?php the_post_thumbnail( 'large', array( 'class' => 'img-responsive' ) ); ?>
</div>
<div class="event-details col-sm-8">
<h2 class="underline"><a href="<?php the_permalink(); ?>"><?php echo $fields->kalendertitel; ?> - <?php $date = get_field('kalenderdag'); ?>
<?php echo date("d M Y", strtotime($date)); ?></a></h2>
<h3 class="underline"><?php the_title(); ?></h3>
<p><?php echo $fields->kalendertext; ?></p>
<p class="call-to-action">Läs mer</p>
</div>
</div>
<?php endwhile; wp_reset_postdata(); ?>
<?php else : ?>
<h2 class="page-title">Just nu har vi inga bokade evenemang</h2>

Can you just put the current ID in as an argument with 'p' => get_the_ID() to your WP_Query?
$args = array(
'p' => get_the_ID(),
'post_type' => 'post',
'posts_per_page' => '20',
'meta_key' => 'kalenderdag',
'order' => 'ASC',
'orderby' => 'meta_value',
'meta_query' => array(
array(
'key' => 'kalenderdag',
'compare' => '>=',
'value' => $today,
'type' => 'DATE'
),
),
);
