Where Do I Add Code in WordPress?

In this article, we will be discussing where you can add code in WordPress. Whether you are a beginner or an intermediate WordPress user, there is likely a section of the WordPress codebase that you would like to explore.

The most popular places to add code in WordPress are in the WordPress codex, in the functions.php file, and in the theme files.

We will look at each of these in turn.

Adding Code in the WordPress Codex

The WordPress Codex is a central location for all of the official WordPress documentation. There, you will find documentation for the core WordPress codebase, as well as for many of the plugins and themes that are available for WordPress.

If you want to add functionality to your WordPress site, or if you just want to learn more about how WordPress works, the WordPress Codex is a great place to start.

Adding Code in the WordPress Functions.php File

The WordPress functions.php file is a central location for all of the WordPress code that is not located in the core codebase.

This file contains functions that are used by many of the core WordPress components, as well as by many of the plugin and theme files.

If you need to add a new function to your WordPress site, or if you want to use a function that is not currently available in the core codebase, you should add your code to the functions.php file.

Adding Code in the WordPress Themes Files

Themes are the visual elements that make up the look and feel of a WordPress site. If you want to create your own theme, or if you want to use an existing theme, you will need to add code to the theme files.

The theme files are located in the wp-content directory, and they contain the code that is used to create the look and feel of a WordPress site.

If you are new to WordPress, or if you are just starting to learn how to create themes, the theme files are a great place to start.
