Add a custom code in WordPress

WordPress is being used in the millions of websites on the web. People love this platform because of its flexibility, such as ability to add a custom code, and the vast array of plugins and themes available to site owners.

However, at times, you may find yourself in situations where currently available plugins on a web are not fully suitable for your needs. In such case, you will need to add custom code to WordPress in order to extend functionality of your site.

The thing is that even a slightest mistake in your custom code can break a WordPress site. In this article, you will learn an easy and safe way on how to add custom code in WordPress without breaking your site.

Wrong way to add custom code

Before providing you different ways of inserting custom functionality to a WordPress site without breaking it, let’s quickly talk what not to do.

You should never directly edit code in WordPress core, plugin or parent theme files. Changes made in such way are not viable for the long-term.

For example, if you’ve decided to add a custom code to functions.php file, or modify any other files in your parent theme, then these changes will be overridden when you update the theme.

The same thing applies for plugins and a WordPress core.

Some users use this as a reason not to update their WordPress site, including themes or plugins. This is a very bad approach. Updates keep your site running smoothly and efficiently because of security patches, bug fixes and new features.

Now, we cant talk about methods to add code snippets to your site in a safe way.

Possible ways to add code snippets

One of the possible methods of extending functionality of your WordPress site is to use a child theme. Child themes are often used for overriding functionality and layouts provided by a parent (main) theme.

When you use a child theme you’ll be able to update the parent theme without losing custom changes you’ve added to your child theme. Here more information about creating a WordPress child theme.

Note, if you are using one of our professional WordPress themes then you do not need to create a child theme. Our premium themes comes with a blank child theme that you can freely use on your WordPress site.

Another possible way to add custom code to WordPress sites is to build a custom plugin. Using a custom plugin is a great way to modify functionality of a WordPress site because you can keep these changes even if you change themes.

However, this method requires advanced coding skills. If you feel comfortable building your own plugin then you can refer the WordPress Codex for more information regarding plugin development.

Easiest way to add custom code snippets

The Code Snippets plugin is an easy way to add custom code to a WordPress site without a need to modify any files on your site. Moreover, your custom code snippet can be inserted to a site in an upgrade-safe way.

Once the plugin is installed and activated on your site, you should see the Snippets link in the main menu section in your dashboard:

  1. Click on Add New to create a new code snippet.
  2. Add a title for your code snippet.
  3. In the Code section, add your code.
  4. Below the Code section, find a section of asking where you want to run your code snippet.
  5. Add description of your code snippet (optional).
