The functions file in WordPress is a template included in themes. It acts like a plugin and integrates with the theme to provide features or change default features on your website. The function.php file uses programming code that adds settings or updates your settings on your website.
For example, a theme might add some code to the theme’s functions.php file in order to provide you with widget areas in the footer, or variances for your dashboard with custom welcome messages. That’s only scratching the surface of what WordPress themes can do!
What Is functions.php in WordPress?
When you install and activate a new theme on your WordPress site, the functions.php file automatically loads to make sure all the necessary code is in place.
Customizing WordPress functions.php is an easy way to add new post types, taxonomies, shortcodes, and more to your website. With these customizations, you can give your website a boost in functionality and design.
Where Is the functions.php File Located?
If you want to add a code snippet, one option is to put that code in the functions.php file.
It’s tempting to combine design and functionality by using WordPress. But WordPress tries to separate these things as much as possible, which is why we use themes for the design and plugins for functionality.
If you want to change your WordPress theme or plugins, try to avoid adversely affecting the way your site functions. It’s best if you can be flexible with both design and function.
Though tutorials might tell you that you need to add code snippets to your theme’s functions.php file, it’s not usually a good idea to do so.
When you edit your functions.php file, it can be risky. Just keep these 3 things in mind:
- Edits to the functions file will be lost when the theme is updated.
- Edits will be lost if you change your WordPress theme.
- Making coding errors in the functions file can lock you out of your site.
Sometimes errors can lead to more serious problems. One of these problems is the WordPress White Screen of Death, which could cause your site to disappear entirely. In the case that this happens, we wrote a step-by-step guide on how to fix it so you can get back into your site and carry on with business as usual.
If you make a mistake in your functions.php file, there’s a chance that this will impact other areas of WordPress as well.
Although you may choose to include any kind of code in your functions.php file, it’s recommended that you only do so if you have more than one active child theme and the code snippets are relevant to your active child theme. For example, a code snippet for custom fonts or stylesheets may work well when they’re applied exclusively to the current child theme.
If you don’t want to mess up your functions.php, where do you eyeball snippets of code from online tutorials?
It’s important to make sure your site has the exciting features that customers want, and that can be tough as a WordPress beginner. Luckily, we have an awesome WPCode plugin that makes adding custom WordPress features easy. You don’t need to edit your theme functions.php file at all!
You can either code your own snippets or use the built-in library of my most popular WordPress code snippets. These will help to eliminate the need for separate plugins, making it a lot easier to get the results you want.
The WordPress snippets will help keep your website more secure, upload SVG images, choose your WordPress editor, and disable comments.
Installing and activating the plugin is easy. Once you’ve done that, you can head over to the Code Snippets page and add your first code snippet to WordPress.
This will bring you to the ‘Add Snippet’ page.
Here you can choose a code snippet from the pre-made library or add your custom code.
