Allow specific post_types to be specified in query

[prettyboymp]

Right now, wp_query only accepts a single post_type or 'any'. It would be nice to be able to specify an array of post_types to use.

This would probably help when using custom post types too. Wouldn't the SQL be better using

elseif ( !empty( $post_type ) && is_array( $post_type ) ) {
  $where .= " AND $wpdb->posts.post_type IN ('" . join("','", $post_type) . "')";
}

latest patch with IN statement

[prettyboymp]

Good call with the sql. I've updated this in attachment:ticket:10791:multiple-post-types.patch​.

By the way, is there anyway to delete an attachment in Trac. I forgot to check the replace file option when uploading a previous version, hence the multiple-post-types.2.patch.

Yes, But only Trac Admins have that ability.

In general, On the WordPress trac its considered best to not replace a existing patch, to allow for those who have downloaded the patch already to see theres a new one there.
