How to Manage and Use Code Snippets in WordPress

In our previous discussions, we explored various WordPress customizations that involve adding code to the functions.php file to enhance theme functionality.

For instance, in our tutorial on customizing the WordPress Login Page, we demonstrated how to redirect users from the default wp-login.php to a customized login page and another page upon logout.

However, as you add more code, functions.php can become cluttered and hard to manage. If you’re facing this issue, we have some practical tips to help you organize your code better.

Organizing Code into Separate Files

To keep your code tidy, consider separating distinct functionalities into different files. For example, if you have several functions modifying the Login Page, store these in a new file named custom-login.php instead of adding directly to functions.php.

Create the file custom-login.php, add your code there, and then include it in functions.php with:

require_once get_template_directory() . '/inc/custom-login.php';

This approach keeps your code organized and minimizes the risk of errors. Make sure to name your files clearly so your team can easily understand their purposes.

If you’re not confident in your PHP skills or worried about potential errors, the following tip might be more suitable for you.

Using the Code Snippets Plugin

Code Snippets is a handy plugin by Shea Bunge that lets you manage your code snippets through a user-friendly WordPress interface, eliminating the need to directly edit functions.php.

After installing and activating the plugin, you’ll find a new menu option under Plugins where you can manage your snippets just like posts or pages.

Create a new snippet, activate it with a click, and it’s ready to use on your site. You can even export snippets as PHP files.

What makes Code Snippets particularly valuable is that your code’s functionality continues even if you change your theme.
