Same image in the thumbnails

Hi hwuser

Try it with this in your (child) theme’s functions.php file:

add_filter( 'related_posts_by_taxonomy_post_thumbnail_link', 'rpbt_related_post_fallback_image', 10, 4 );
 
function rpbt_related_post_fallback_image( $image, $attr, $related, $args ) {
   	$featured = get_the_post_thumbnail( $related, $args['size'], $attr['describedby'] );
 
    return "<a href='{$attr['permalink']}'>{$image}</a>";
}

btw:
consider creating a child theme instead of editing your theme directly – if you upgrade the theme all your modifications will be lost. Or create a plugin with the code above.

Oh, I see now that code indeed does nothing 🙂

Try it with this

add_filter( 'related_posts_by_taxonomy_post_thumbnail_link', 'rpbt_related_post_fallback_image', 10, 4 );
 
function rpbt_related_post_fallback_image( $image, $attr, $related, $args ) {
   	$featured = get_the_post_thumbnail( $related, $args['size'], $attr['describedby'] );
 
    return "<a href='{$attr['permalink']}'>{$featured}</a>";
}

I think the reason the post thumbnails are all the same is because the featured image from url plugin filters the WordPress post thumbnail output. My plugin (at this moment) doesn’t use the get_the_post_thumbnail() function to get the post thumbnail image. I hope this makes sense.

You’re welcome 🙂
