The beauty of WordPress is in how easy it is to adapt for different tasks. One can extend it with just a couple of lines of code. In this post, we’ll review 10 shortcode snippets that will tweak and optimize your WordPress theme. You can add all of these code snippets to the functions.php file in your WordPress theme.

Limit The Excerpt’s Word Count

One thing that can go wrong in WordPress magazine themes is when users include too many words before the more tag. Sure, they could handcraft the excerpt in the dedicated field, but on a website that has hundreds of posts and on which the text above the more tag has always been used as the excerpt, going back to create excerpts for all of those posts by hand would be cumbersome. In this case, we can limit the number of words shown in the excerpt by using this code:

1 add_filter('excerpt_length', 'ilc_excerpt_length');
2 function ilc_excerpt_length( $length ){
3     return 10;
4 }

Here, we’re using a WordPress filter hook, which is a function that parses and (usually) modifies data before it gets stored in the database or displayed on a page. In this case, we’re setting the number of words shown in the excerpt to 10.

Add A Favicon Using A WordPress Hook

Hooks allow us to insert custom code without touching the template. This gives us a lot of flexibility, because now, whenever we need to change something, we only have to change the function that’s plugged into a certain hook. For example, you can add a favicon to your website without touching the header.php file, just by plugging a function into the wp_head hook:

1 add_action( 'wp_head', 'ilc_favicon');
2 function ilc_favicon(){
3     echo "<link rel='shortcut icon' href='" . get_stylesheet_directory_uri() . "/favicon.ico' />" . "\n";
4 }

The favicon.ico file should be located at the root of your theme. We’re now using an action hook, which is a function that is triggered at specific points during an execution by WordPress’ core. In this case, the hook triggers any function that’s attached to it when a page is launched in the browser. But other hooks can be triggered when saving a post, registering a user and so on. Some themes even have their own action hooks, which, like WordPress’ core action hooks, can be used to launch functions at specific points of an execution.

Redirect WordPress Feeds To FeedBurner

It’s great that WordPress offers feeds out of the box. But if you want statistics about your subscribers, you’ll have to use FeedBurner or a similar service. To redirect your feed to one of these, use the following snippet. Thus, if you try to go to (, you’ll be redirected to FeedBurner’s feeds for Smashing Magazine (

1 add_action('template_redirect', 'ilc_rss_redirect');
2 function ilc_rss_redirect() {
3     if ( is_feed() && !preg_match('/feedburner|feedvalidator/i', $_SERVER['HTTP_USER_AGENT'])){
4         header('Location:');
5         header('HTTP/1.1 302 Temporary Redirect');
6     }
7 }

Replace with the URL for your own feed from FeedBurner.
