How to set default archive image without overriding first attached image? [closed]
You could use get_attached_media() function to check if the post has any attached images to it. Also, you use wrong logic operator. Your code would look like this: $attached_images = get_attached_media(‘image’, $post->ID); if ( (get_the_post_thumbnail() == NULL) && empty($attached_images) ) { // show your default image } else { // do nothing, I guess? }
