Hi @qhuit

In this case, you need to pass the total number of the products to the array_rand() function like this:

<?php
$repeater = get_field('products');

// get 4 keys of the repeater
$repeater_keys = array_rand($repeater, 4);

if($repeater):

	echo "<section class='shopThis'>
        <h3 class='title md-col-3'>Shop this in our store</h3>
        <!--<p>This article is available in our brand new online store.<br>-->
        <p>We brought a few things back from this trip, and it's now available in our brand new online store.<br />
        Gets yours by clicking here!</p>
        
        <div class='articles_container'>";
    
    // loop through the keys
    foreach( $repeater_keys as $repeater_key ){
        
        //get the post object using the repeater key
        $post_object = $repeater[$repeater_key]['product_image'];
            
        if( $post_object ){
            $post = $post_object;
            setup_postdata($post);
            ?>

            <article>
                <a href="<?php echo the_permalink();?>"><?php the_post_thumbnail();?></a>
                <a href="<?php echo the_permalink();?>" class="btn">shop this</a>
            </article>
            
            <?php
        }
        
    }
    
    wp_reset_postdata();
    
    echo "</div>
        </section>";

endif; ?>

Hope this helps 🙂
