Wordpress Category Thumbnail List Plugin - php

Question

I'm trying to tweak a Wordpress Plugin - Category Thumbnail List to display "Coming Soon" when the shortcode calls for posts in a category but there are none.
I've tried contacting the developer but had no luck.
I've modified the original code using the following but it doesn't display. Any ideas?
foreach($myposts as $post) :
setup_postdata($post);
if ( has_post_thumbnail() ) {
$link = get_permalink($post->ID);
$thmb = get_the_post_thumbnail($post->ID,'thumbnail');
$title = get_the_title();
$output .= '<div class="categoryThumbnailList_item">';
$output .= '' .$thmb . '<br/>';
$output .= '' .$title . '';
$output .= '</div>';
} else {
$output .= '<p>Coming Soon</p>';
}
endforeach;
Here's the full code:
<?php

Update the thumbnail sizes here

<div>
You may need to update your css when changing the thumbnail size
</div>
</form>

Many Thanks,

Haven't tested your code, but a quick glance shows at least one problem... you're using this outside of the loop. When not used in the loop, has_post_thumbnail() doesn't know what post you're checking. With just that modification, your code should be this:
foreach($myposts as $post) :
setup_postdata($post);
if ( has_post_thumbnail( $post->ID ) ) {
$link = get_permalink($post->ID);
$thmb = get_the_post_thumbnail($post->ID,'thumbnail');
$title = get_the_title();
$output .= '<div class="categoryThumbnailList_item">';
$output .= '' .$thmb . '<br/>';
$output .= '' .$title . '';
$output .= '</div>';
} else {
$output .= '<p>Coming Soon</p>';
}
endforeach;
