The MU forums have moved to

Trying to add up all comments (7 posts)

    I copied the code from /wp-admin/index.php to get the comment count from one blog and tried making it add up the comments for all the blogs across my wpmu install, but its not working:

    require ('wp-config.php');

    $res = mysql_query("SELECT blog_id from wp_blogs");
    while ($line = mysql_fetch_array($res)) {
    $id = $line['blog_id'];
    $comments = (int) $wpdb->get_var("SELECT COUNT(*) FROM wp_${id}_comments WHERE comment_approved = '1'");

    echo $id;

    What am I doing wrong? If I replace wp_${id}_comments with wp_1_comments it will give me the correct value. I just dont know how to make it all add up :D

    im using this: (Credits to Stian, for helping sorting it out)

    $query = "SHOW TABLES LIKE 'wp_%_comments'";
    $result = mysql_query($query);

    while($row = mysql_fetch_array($result, MYSQL_NUM)) {
    $tables2[] = $row[0];

    $query3 = "SELECT SUM(antal) FROM ((SELECT COUNT(*) AS antal FROM ";
    $query3 .= implode(" WHERE comment_approved = '1' ) UNION ( SELECT COUNT(*) AS antal FROM ", $tables2);
    $query3 .= ")) AS temp";

    $results2 = mysql_query($query3);
    $comment_count = mysql_result($results2, 0);

    echo $comment_count; ?>

    Enjoy, naturaly it can be applied to posts aswell if u edit it.

    Hmm, made it work with posts as well and all is fine. Antal is a swedish word right?

    I wonder how much of a strain would adding this to the front page mean. I have to decide now if I should make a separate page for stats or not :)

    hehe yes sorry cleaned it from swedish but must have missed that one, "antal" means "amount" or "number of"

    i have a few plugins over at, calling all sorts of stats over there, the one thing im still looking for is amount of posts in each blog. but im getting there ;)

    print "<table>";
        #$blogs = get_blog_list();
        #print "<br>blogs: <br>";
        #print_r( $blogs );
        $most_active = get_most_active_blogs( 10, false );
        if( is_array( $most_active ) ) {
    	print "<caption>Most Active Blogs</caption>";
    	print "<tr><th scope='col'>ID</th><th scope='col'>Address</th><th scope='col'>Posts</th></tr>";
    	while( list( $key, $details ) = each( $most_active ) ) {
    	    $class = ('alternate' == $class) ? '' : 'alternate';
    	    $url = "http://" . $details[ 'domain' ] . $details[ 'path' ];
    	    print "<tr class='$class'><td>" . $details[ 'blog_id' ] . "</td><td><a href='$url'>$url</a></td><td>" . $details[ 'postcount' ] . "</td></tr>";
        print "</table>";

    This'll get the top ten blogs by number of posts. First line you can change the list. Someone else here wrote it, but I couldn't find the original thread.
