Include Post Excerpt ?

You want this plugin can count the post views times when you use the_excerpt(); function to display.
The most easy way is find
　add_filter('the_content', 'process_postviews');
and add the code
　add_filter('the_excerpt', 'process_postviews');
after what you find

I will do more test, and release a new version

What I really need to do is display the post content (ONLY before the <!–more–> tag). I am able to add the entire post content by using “post_content”, however I just want to display the content before the <!–more–>…

I have to edit something here (line 151 in postviews.php):

if($chars > 0) {
				foreach ($most_viewed as $post) {
					$post_title = htmlspecialchars(stripslashes($post->post_title));

					$post_views = intval($post->views);
					$post_views = number_format($post_views);
					$temp .= "<li><a href=\"".get_permalink()."\">".snippet_chars($post_title, $chars)."</a></li>\n";

				}
			} else {
				foreach ($most_viewed as $post) {
					$post_title = htmlspecialchars(stripslashes($post->post_title));

					$post_views = intval($post->views);
					$post_views = number_format($post_views);
					$temp .= "<li><a href=\"".get_permalink()."\">$post_title</a></li>\n";

				}

I cannot find add_filter('the_content', 'process_postviews');

Sorry To You!
I think you are using WP-PostViews From Lester ‘GaMerZ’ Chan.
It,s not the same.
