I have this SQL and it is working. but it only picks out the comments of the main blog. can anyone point me in the right direction?
<?php
global $wpdb, $wpmuBaseTablePrefix;
$blogs = $wpdb->get_col("SELECT <code>blog_id</code> FROM $wpdb->blogs
WHERE <code>public</code> = '1' AND <code>archived</code> = '0' AND <code>last_updated</code> != '0000-00-00 00:00:00'
ORDER BY <code>last_updated</code> DESC LIMIT ");
if (!is_array($blogs)) return false; // New Site?
foreach($blogs as $blogid)
global $wpdb, $wpmuBaseTablePrefix;
$sql = "SELECT DISTINCT ID, post_title, post_password, comment_ID,
comment_post_ID, comment_author, comment_date_gmt, comment_approved,
comment_type,comment_author_url,
SUBSTRING(comment_content,1,300) AS com_excerpt
FROM $wpdb->comments
LEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID =
$wpdb->posts.ID)
WHERE comment_approved = '1' AND comment_type = '' AND
post_password = ''
ORDER BY comment_date_gmt DESC
LIMIT 10";
$comments = $wpdb->get_results($sql);
$output = $pre_HTML;
$output .= "\n<ul>";
foreach ($comments as $comment) {
$output .= "\n<li> <a href=\"" . get_permalink($comment->ID) ."#comment-" . $comment->comment_ID . "\" \">" .strip_tags($comment->comment_author)." på " .$comment->post_title . "</a><br />" . strip_tags($comment->com_excerpt). "</li>";
}
$output .= "\n</ul>";
$output .= $post_HTML;
echo $output;?>
