Preview Image Path in Admin Section

So I have run into a little glitch. i have a custom path for uploads and it works. the files get saved to the right place, etc. The problem I have is the ‘widget box’ in the admin section. immediately after uploading and setting the uploaded image as the featured image, it show up in the preview, instead of
www.blog.com/blog/uploads/POST_ID/image_name.png
it is showing

www.blog.com/blog/uploads/image_name.png
The path is broken. Again I am new to WP… is there a filter for the admin ‘widget box’s?

The path I get back is:
<img width="266" height="145" src="https://mysite.com/blog/wp-content/uploads/image-350x192.png" class="attachment-266x266" alt="the title" title="the title">

But where the image resides is:
<img width="266" height="145" src="https://mysite.com/blog/wp-content/uploads/<POST_ID>/image-350x192.png" class="attachment-266x266" alt="the title" title="the title">

I cant add an image because of my rep so far… it appears in the same column as tags and categories in the admin area. It is a custom widget for this theme.

update

    function media_upload_dir($upload) {
        if(!isset($_REQUEST['post_id']))
        return $upload;
$id = $_REQUEST['post_id'];
        if (isset($_REQUEST['post_id'])) {
            $upload['path']    = "/path/www/blog/wp-content/uploads/" . $id;
            $upload['url']     = "http://site.com/blog/wp-content/uploads/" . $id;
            $upload['basedir'] = "/path/www/blog/wp-content/uploads/" . $id;
            $upload['baseurl'] = "http://site.com/blog/wp-content/uploads/" . $id;
            if (!file_exists("/path/www/blog/wp-content/uploads/" . $id)) {
                mkdir("/path/www/blog/wp-content/uploads/" . $id, 0777);
            }
        }
        return $upload;
    }
    add_filter('upload_dir', 'media_upload_dir');

This is not a answer, is an extended comment with the link to the solution.

First, while testing, one of my test sites wasn’t showing the Featured Image uploaded to the folder /wp-content/uploads/POST_ID/image_name.jpg. Same problem as the OP.

But, it was not displaying any path to the image. And the bug was that the installation where I was testing is full of hacks (my main WPSE testing base). As soon as I went to a stable installation everything worked.

So, if your problem persist, do a full troubleshooting:

Also, Robert, when asking a question please provide all the elements that a person who is willing to help will need to understand and effectively answer it.

Side notes to your code:

• mkdir is not necessary, WordPress handles this
• don’t hardcode the path or URL of wp-content, you can use the constants WP_CONTENT_DIR and WP_CONTENT_URL

Best regards and good luck!
