Some time we shows the posts and there comments in sidebar. But what to do for show the comments for custom post type.
It’s not well documented, but according to the codex, you can pass a ‘post_type’ variable in the get_comments function.
$comments = get_comments('number=10&status=approve&post_type=YOUR_POST_TYPE');
foreach($comments as $comment) :
// comment loop code will go here
Note: This code only useful after wordpress 3.1 version.
