Hook Fundamentals: What Are Hooks?

In the world of WordPress, Hooks are the key to modifying core behavior without changing the core code. They create a bridge for developers to interact with default WordPress processes, or in other words, they act as a line of communication between your plugin or theme and WordPress. They provide developers the freedom to change the default behavior or functionality of WordPress without changing any core files which could lead to disaster when WordPress is updated.

Hooks are divided into two types: actions and filters. Action hooks allow you to add new functionality or data to your site, whereas filters let you manipulate the existing functionality or data. Understanding the usage of hooks and how they interact with your WordPress site can open up an entirely new world of customization opportunities.

Why Use Hooks?

Hooks have dramatically changed the way developers approach WordPress design — they’ve evolved from being just a tool in the developer’s toolbox to an integral part of WordPress’ DNA. If you ask why do you need to use hooks, the answer is simple: hooks offer a quick and easy way to add, modify, or remove functionality from your WordPress site, significantly boosting its functionality. They offer a flexible way to add, modify, and delete functionality, providing a method to create custom functionality without affecting the core code of your site, thus maintaining the stability and security of your website.

Using hooks also enables you to future-proof your customizations. Suppose, you’ve made changes to your site’s core WordPress code. What happens when you need to update WordPress to its latest version? The update would overwrite all your hard work, causing you to lose the customizations. However, with hooks, custom code can be created separately in plugins or theme’s functions.php file ensuring that your modifications are preserved even after WordPress updates. Simply put, hooks let you modify and extend your website safely and efficiently without breaking anything.

A Deep Dive Into feed_links_extra_show_post_comments_feed


While there are countless hooks in WordPress that you can use to customize your site, one that we find particularly interesting is ‘feed_links_extra_show_post_comments_feed’. But what exactly is this hook and what does it do?

The ‘feed_links_extra_show_post_comments_feed’ is a specific type of hook—a filter hook that gives you control over how to display feed links in your html header. By altering the return value of this hook, you can modify the behavior of the website’s feed links. It modifies the ‘feed_links_extra’ function, and can be incredibly beneficial for customization purposes.


Coding with hooks may seem daunting at first, but once you’re comfortable with the syntax, using them is straightforward. To help illustrate, let’s see how the ‘feed_links_extra_show_post_comments_feed’ hook can be used in a practical scenario.

Below is a simple snippet of code showing how ‘feed_links_extra_show_post_comments_feed’ is employed:

      function remove_comments_rss( $for_comments ) {
      add_filter('feed_links_extra_show_post_comments_feed', 'remove_comments_rss');

This piece of code disables the link in the header to the comments feed. This comes in handy if we don’t have comments on our posts – there’s no need for a link to the comments feed in the header in such a case.

Use Cases

Now that we’ve seen the basic application, let’s talk about specific use cases. Why would you want to use the ‘feed_links_extra_show_post_comments_feed’ Hook in a practical scenario?

The applications of ‘feed_links_extra_show_post_comments_feed’ are far-reaching. Here are a couple of instances where you could use this hook effectively:

  • Streamline website headers: If your WordPress site doesn’t have comments enabled, using this hook helps you declutter your website’s HTML header by eliminating unnecessary links to comments feed. This clean up not only makes your website code cleaner and more readable but leaves a good impression on anyone who might be examining your site’s code.
  • Boost website performance: Links to unused features — like a comments RSS feed when you don’t have comments enabled — add to the bloat on your website and can slow it down. Cleaner, leaner code means lesser load time for your website, which in turn contributes towards a better overall performance.

Best Practices

While it’s easy to get excited about the customization potential of hooks like ‘feed_links_extra_show_post_comments_feed’, it’s equally important to use these features responsibly. Here are some best-use practices when it comes to WordPress hooks:

  • Use a child theme: When making changes to your website using hooks, always employ a child theme. This way, if something goes wrong, you can easily revert to the parent theme without losing the design and functionality customizations you’ve made.
  • Always test on a development site: Before making changes to your live site, test the hook on a development or staging site first.
  • Write clean code: This makes it easier for others to understand your code and for you to debug if something goes wrong.


If you encounter issues when using the ‘feed_links_extra_show_post_comments_feed’ hook, here are a few solutions you can try:

  • Check your syntax: A small syntax error is often the culprit. Double-check your code to ensure it is correct.
  • Clear cache: Sometimes cache can create issues, particularly if you’re not seeing the changes you’re expecting. A good solution is to clear your cache – both of your browser and of your WordPress install.
  • Check compatibility: Sometimes, the WordPress theme, plugins or even WordPress core might have updates pending. Make sure everything is up-to-date and make sure that the changes you’re making are compatible with the latest versions of WordPress, your theme and any active plugins on your site.

Examples of Other Useful Hooks

Beyond ‘feed_links_extra_show_post_comments_feed’, there are countless other hooks that you can use to customize WordPress. Here are examples of a few hooks that can drastically change your website functionalities:

  • ‘wp_head’: This hook allows you to add custom meta tags, custom CSS, and more to the website’s header.

  • ‘the_content’: This filter hook is useful for modifying the content of your posts.
  • ‘widget_title’: This hook is used to change the title of widgets on your website.

Each of these hooks serves a unique function in WordPress development and provides vast potential for customization.
