Would you like to display the total number of posts, comments, and categories for your WordPress-powered website? Here is the code that can make it happen ¹!

Update: The count posts part of this method should only be used for WordPress versions less than 2.5. For WordPress versions 2.5 and better, there is a built-in function for displaying the total number of posts. See The WordPress Codex for more information.

<?php
$numposts = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_status = 'publish'");
if (0 < $numposts) $numposts = number_format($numposts);

$numcomms = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments WHERE comment_approved = '1'");
if (0 < $numcomms) $numcomms = number_format($numcomms);

$numcats = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->categories");
if (0 < $numcats) $numcats = number_format($numcats);
?>
<p><?php printf(__('There are currently %1$s <a href="%2$s" title="Posts">posts</a> and %3$s <a href="%4$s" title="Comments">comments</a>, contained within %5$s <a href="%6$s" title="categories">categories</a>.'), $numposts, 'edit.php',  $numcomms, 'edit-comments.php', $numcats, 'categories.php'); ?></p>

Here is a modified version of the code, customized for our use here at Perishable Press:

<?php
$numposts = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_status = 'publish'");
if (0 < $numposts) $numposts = number_format($numposts);
$numcomms = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments WHERE comment_approved = '1'");
if (0 < $numcomms) $numcomms = number_format($numcomms);
$numcats = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->categories");
if (0 < $numcats) $numcats = number_format($numcats);
?>

<?php echo $numposts . ' posts and ' . $numcomms . ' comments in ' . $numcats . ' categories'; ?>
