I grabbed the standard WordPress gallery shortcode from line ~758 in wp-includes/media.php and pasted it into my_theme/functions.php for modification. For the more adventurous folks you can override the default WordPress gallery shortcode and then galleries you’ve inserted using the Media Gallery will be lightboxed.

Here’s the code I ended up with in functions.php (shortened for readability, you’ll need to C&P the entire shortcode function from wp-includes/media.php):

add_shortcode('my_gallery_shortcode', 'my_gallery_shortcode_function');
 
function my_gallery_shortcode_function($attr) {
	global $post, $wp_locale;
	...
	foreach ( $attachments as $id => $attachment ) {
		$link = isset($attr['link']) && 'file' == $attr['link'] ? wp_get_attachment_link($id, $size, false, false) : wp_get_attachment_link($id, $size, true, false);
 
		//add rel="prettyPhoto[pp_gal]"
		$link = str_replace('><img','rel="prettyPhoto[pp_gal]" ><img',$link);
 
		$output .= "<{$itemtag} class='gallery-item'>";
		$output .= "
			<{$icontag} class='gallery-icon'>
				$link
			</{$icontag}>";
		if ( $captiontag && trim($attachment->post_excerpt) ) {
			$output .= "
				<{$captiontag} class='wp-caption-text gallery-caption'>
				" . wptexturize($attachment->post_excerpt) . "
				</{$captiontag}>";
		}
		$output .= "</{$itemtag}>";
		if ( $columns > 0 && ++$i % $columns == 0 )
			$output .= '<br style="clear: both" />';
	}
 
	$output .= "
			<br style='clear: both;' />
		</div>\n";
 
	return $output;
}

My edit was small, I added $link=str_replace('><img','rel="prettyPhoto[pp_gal]" ><img',$link); to the gallery output so that PrettyPhoto can do it’s thing.

Now that you have that all you need to do is be sure you’re including the necessary files:

<link rel="stylesheet" type="text/css" media="all" href="<?=bloginfo('template_directory');?>/prettyPhoto/css/prettyPhoto.css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script type="text/javascript" src="<?=bloginfo('template_directory');?>/prettyPhoto/js/jquery.prettyPhoto.js"></script>

And be sure to call PrettyPhoto:

<script type="text/javascript" charset="utf-8">
	$(document).ready(function(){
		$("a[rel^='prettyPhoto']").prettyPhoto();
	}); 
</script>

Now all you need to do is upload photos to your gallery and use this shortcode on your page:

[my_gallery_shortcode link="file"]

And that’s it! A quick solution to adding a lightbox to your WordPress gallery.

I started with get_comment_excerpt() from line ~407 of wp-includes/comment-template.php and pasted it into my_name/functions.php to be modified.

Here’s what I ended up with:

function my_get_comment_excerpt($comment_ID = 0, $num_words = 20) {
	$comment = get_comment( $comment_ID );
	$comment_text = strip_tags($comment->comment_content);
	$blah = explode(' ', $comment_text);
	if (count($blah) > $num_words) {
		$k = $num_words;
		$use_dotdotdot = 1;
	} else {
		$k = count($blah);
		$use_dotdotdot = 0;
	}
	$excerpt = '';
	for ($i=0; $i<$k; $i++) {
		$excerpt .= $blah[$i] . ' ';
	}
	$excerpt .= ($use_dotdotdot) ? '...' : '';
	return apply_filters('get_comment_excerpt', $excerpt);
}

And here’s a little code to output a list of comments using this function:

<ul>
<?php 
	$comments = get_comments();
	foreach($comments as $c) :
?>
<li>
	<a href="<?php echo get_permalink($c->comment_post_ID); ?>">
		<?php /* output 10 words of comment */ ?>
		<p><?php echo my_get_comment_excerpt($c->comment_ID, 10); ?></p>		
		<span><?php echo $c->comment_author; ?></span>
		<span><?php echo date("m/j/Y",strtotime($c->comment_date)); ?> </span>
	</a>
</li>
<?php
	endforeach;
?>
</ul>

I cooked up a quick shortcode function using some of their product list code that will query the products by the passed category and output them using the product template.

First, place the following code in my_theme/functions.php:

function my_wpsc_products_shortcode($atts) {
	$number_per_page = get_option('use_pagination') ? get_option('wpsc_products_per_page') : 0;
	$query = shortcode_atts(array(
		'category_id' => isset($atts['cat']) ? $atts['cat'] : 0,
		'limit_of_items' => 0,
		'sort_order' => null,
		'number_per_page' => $number_per_page,
		'page' => 0,
	), $atts);
 
	return wpsc_display_products_page($query);
}
add_shortcode('my_wpsc_category', 'my_wpsc_products_shortcode');

Once that’s done you’ll be able to use [my_wpsc_category cat=6 /], where 6 is the integer ID of the category, on whichever page you want the products displayed on.

This list will be output using the wpsc-single_product.php template or the wpsc-products_page.php template, depending on whether you have multiple products in the category.

Google Analytics was showing normal pageview numbers, so we knew something was amiss. When we looked at the most viewed pages in awstats, it became obvious:

AWStats has always counted pageviews on the WordPress backend, but compared to the total pageviews the impact was negligible. However, now that WordPress 2.7 makes so many AJAX calls to admin-ajax.php (primarily for saving drafts), we must exclude these pageviews from our reports to leave meaningful data. Thankfully its very easy.

We’re going to instruct awstats to ignore hits on any page in the wp-admin directory. Alternatively, we could have AWStats ignore our IP address, which has its own merits, but this approach becomes cumbersome when multiple authors and dynamic IPs come into play.

Instructions:

1. Open the awstats .conf file which corresponds to your domain. On most shared hosting accounts this will be located in /tmp/awstats/. If you see more than one .conf file, choose the one which matches the domain of the site you are working on.
2. Look for the line which starts with:

   SkipFiles="

   AWStats is usually already configured to exclude robots.txt and favicon.ico, so the line probably looks like this:

   SkipFiles="robots.txt$ favicon.ico$"

3. Append the following string after the last filename listed (make sure to leave a space), but before the quote:

    REGEX[^/wp-admin/]

   If you’re file looks like mine, the line should now read:

   SkipFiles="robots.txt$ favicon.ico$ REGEX[^/wp-admin/]"

4. Save and upload the file. If you’re on shared hosting, you’ll want to CHMOD the .conf file to 444, otherwise your changes are likely to be overwritten.

That’s it! This change is not retroactive, but if all went well you should be able to write a new post in WordPress and the pageviews for admin-ajax.php will not increase.
