Hi @miksynder
You would need to query your posts to see if your custom field exists, something like:
<?php
$args = array(
'post_type' => array('post', 'page'),
'posts_per_page' => 10,
'post_status' => 'publish',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'start_date',
'compare' => 'EXISTS',
),
),
);
// query
$the_query = new WP_Query( $args );
?>
<?php if( $the_query->have_posts() ): ?>
<h2>Amazing Events List</h2>
<ul>
<?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
<?php $start_date = get_field('start_date');?>
<li>
<a href="<?php the_permalink(); ?>">
<?php if($start_date): echo $start_date; endif; ?>
<?php the_title(); ?>
</a>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
<?php wp_reset_query(); // Restore global post data stomped by the_post(). ?>
