I want to display the list of related posts at the end of my blog post. I would like the main image to display if possible, but I can't seem to get this to work right. Any help would be a appreciated.

    You should be able to loop through the related posts like so:
    foreach($post->related_posts as $related) : echo $related->main_image; endforeach;

    Thank you for replying. And that piece of code helped me load one related post, but it's not displaying all the related posts.

    I also removed "endforeach;" because it caused an error.

    Here's what I have:

    php foreach($post->related_posts as $related)
    php if (!empty($related)) :
    php echo $related->thumbnail_image

    php endif;

    The code above was missing the ending semicolon after:
    echo $related->main_image;

    The semi colon is there in my version, I must have missed it when I cut and pasted.

    It still isn't showing all the images. It's only showing 1 image.

    Just to confirm, each post has a main_image value associated with it? What is showing instead?

    I have a thumbnail image in the database as well as a main image. They are different images.

    I tried the suggested:

    echo $related->main_image;

    but it gave me the same results with the main image. It only displays one.

    So when you execute that foreach loop above, does it loop through all the related posts for the selected post and output the main_image for each related post or does it output something different and if so what does it output for each related post main_image value?

    It only outputs one of the related posts, and returns the image for it.

    How many posts are associated with it under the Associations tab?

    One of the posts has 2, another has 4. Only one related post for each is showing.

    Hmm...I'm not able to replicate this issue. I tested it with the following and it behaved as expected:
    $related = $post->related_posts; foreach($post->related_posts as $p) : echo '<img src="'.$p->thumbnail_image.'"><br>'; endforeach;

    Awesome! That worked for me.

    Where it echo's the image src I had to include a path to the folder for the images to load.

    echo '<img src="/assets/images/blog'.$p->thumbnail_image.'"><br>';


    Thank you.
