Hi,
I am trying to figure out how to get the post object to auto fill for a post type.

So the logic would go like this. If the related posts are not set it would go and get 4 random posts in the post type.

here is what I have to set the post manualy. How do I get it to auto fill if I don’t put anything in?

<div class="row no-gutters">
    <?php $post_objects = get_field('testimonials_related');
    
    if( $post_objects ): ?>
    
        <?php foreach( $post_objects as $post_object): ?>
            
                <div class="col-xs-6 col-sm-3 ">
                    <?php $video_id = get_post_meta( $post_object->ID, 'youtube_video_main', true ); ?>
                    <a href="<?php echo get_permalink($post_object->ID); ?>">
                        <img src="http://img.youtube.com/vi/<?php echo $video_id; ?>/mqdefault.jpg" />
                    </a>
                </div>
    
        <?php endforeach; ?>
    
    <?php endif; ?>
</div>

Untested but here’s something to get you started:

$post_objects = get_field( 'testimonials_related' );

if ( $post_objects ) {
	// your normal stuff here..
} else {
	// no post objects found, query the post type for 4 random posts
	// you should cache this query with either the object cache or transients api
	// http://wordpress.stackexchange.com/questions/183698/way-to-cache-a-query-for-24-hrs
	$current_post_id = get_the_id();
	$testimonials = new WP_Query(
		'post_type' => 'testimonials',
		'post_status' => 'publish',
		'posts_per_page' => 4,
		'orderby' => 'rand',
		'post__not_in' => array( $current_post_id ) // exclude the current post
	);
	
	if ( $testimonials->have_posts() ) {
		while ( $testimonials->have_posts() ) {
			$testimonials->the_post();
			// display the posts...
		}
		wp_reset_postdata();
	}
}
