Add support multiple comment types in get_comments

[borkweb]

Custom comment types are a nice way to categorize comments, however, if you wish to retrieve multiple comment types you cannot use get_comments. This enhancement request (patch attached) adds support for multiple comment types a la:

$comments = get_comments( array(
  'post_id' => $post->ID,
  'type' => array(
    'a-sweet-comment-type',
    'some-other-comment-type',
  ),
));

+1 I have a couple of use cases this would be very helpful for, e.g. displaying a custom comment type in a loop with regular comments, without doing multiple comment queries and then merging the resulting data. This is particularly important because I have more comment types than I want to display, so displaying all the types would not work.

I'd like to weigh and add my vote for this enhancement. I'm currently working on a plugin that uses custom comment types and this would definitely make querying multiple types in a single request a lot easier.

Also, I think it makes a lot of sense, because then it would reflect the logic in WP_Query which allows querying posts using an array of post types.

borkweb, thanks for the patch. As of [30096], the 'type' parameter accepts an array of types. We also now have a 'typein' param.
