Adding Code Snippets in WordPress: A Quick Guide

How to Add Code Snippets in WordPress

Sometimes you want to change something in WordPress. This could be a design element such as social link placement on mobile, a core function like comments, or a monetization feature like ad placement. Often the solution is to use a plugin, but if all you need is to make one edit why go through all the hassle of installing and configuring a plugin? That’s where code snippets come in handy.

Code snippets are small pieces of code that can be added to your WordPress website to modify its functionality. They can be used to add new features, customize existing ones, or fix issues. In this article, we will show you how to add code snippets in WordPress.

Why Use Code Snippets?

Using code snippets instead of plugins has several advantages. First, it allows you to make specific changes without affecting the rest of your website. This means you can customize your site exactly the way you want without any unnecessary bloat.

Second, code snippets are lightweight and don’t require additional resources like plugins do. This can help improve your website’s performance and load times.

Finally, code snippets give you more control over your website. You can easily modify or remove them whenever you want without having to uninstall a plugin.

Adding Code Snippets in WordPress

There are several ways to add code snippets to your WordPress website. We will cover three methods: using a plugin, adding code directly to your theme’s functions.php file, and using a custom plugin.

1. Using a Plugin

The easiest way to add code snippets to your WordPress site is by using a plugin. There are several plugins available that allow you to add and manage code snippets.

One popular plugin is Code Snippets. After installing and activating the plugin, you can navigate to “Snippets” in your WordPress dashboard. From there, you can add new snippets, edit existing ones, and activate or deactivate them as needed.

2. Adding Code to Your Theme’s functions.php File

If you prefer not to use a plugin, you can add code snippets directly to your theme’s functions.php file. This file is located in your theme’s folder and contains all the functions that control how your theme works.

To add a code snippet, simply open the functions.php file in a text editor and paste the code at the end of the file. Make sure to save the changes before closing the file.

It’s important to note that editing your theme’s functions.php file directly is not recommended if you are using a parent theme. Any changes you make will be overwritten when the theme is updated. In this case, it’s better to use a child theme or a plugin.

3. Using a Custom Plugin

If you want more control over your code snippets and don’t want to rely on a third-party plugin, you can create your own custom plugin. This allows you to add and manage code snippets without cluttering your theme’s files.

To create a custom plugin, you need to create a new folder in the wp-content/plugins directory of your WordPress installation. Inside this folder, create a new PHP file and add the following code:



Plugin Name: Custom Code Snippets

Description: Adds custom code snippets to modify WordPress functionality.


// Add your code snippets here


You can then add your code snippets below the comment. Save the file and navigate to the “Plugins” section in your WordPress dashboard. You should see your custom plugin listed there. Activate it, and your code snippets will be applied to your website.


Code snippets are a powerful tool for customizing and extending the functionality of your WordPress website. Whether you choose to use a plugin, add code directly to your theme’s functions.php file, or create a custom plugin, adding code snippets allows you to make specific changes without the need for unnecessary plugins.

Remember to always test your code snippets on a staging or development site before applying them to your live website. This will help you avoid any potential issues and ensure that your website continues to function properly.

So the next time you need to make a small tweak to your WordPress site, consider using code snippets instead of installing a plugin. You’ll have more control, better performance, and a cleaner website overall.
