Each Webshop is different and they are also your desires for how your websites should work. You may already have chosen a Woocommerce theme that has almost all of the functions you need, but there are still regular adjustments to improve your website. Many of these adjustments can be done directly in your child’s subject Function.PHP. In this article, you will learn everything about this file and how to deal with it.

What is the Function.php file where can I find it?

WordPress has chosen a specific file structure for topics and the FUNCTIONS.PHP file is a part. As the name implies, this file must contain functions. When a subject is loaded with WordPress, the system also looks at what functions are called in the Function.PHP file. This is quite late in the process, so you can overwrite or even deactivate existing functions.

Therefore, each topic has a Function.php file. If the file is missing, the subject will not work and you will get an error message. You can find the file using a SFTP connection to your website in the/WP-CONTIN-CONTE/THEMES/YOURTHEME/

Note that you just have to modify the file in the subject folder if it is a subject specifically written for your website. In almost every case, you must use a childhood topic …

No WordPress website without childhood topic

If you use a topic chosen in WordPress deposit or bought a premium topic from a WordPress topics developer, you will receive regular updates. During this update, all the changes you have made to your topic will be overwriteed.

To avoid -always use a children’s topic. If you do not have a children’s topic yet, it’s time to create one.

How can I edit the Function.php file?

When you install WordPress in a predetermined manner, you can also edit the Function.PHP file through the board. We recommend you not. This way, you will not have a backup of the original version and, if you enter a bad code, you may even after a WordPress check that your website stops working. If you do not have SFTP access, you may not be able to fix the error quickly. You can do better in the following way:

1. Download the Function.php file on your laptop and save a copy as a backup.
2. Open the file in a PHP publisher. We recommend Claudators, a free text publisher that works with Windows and Mac.
3. Now edit the code and save the file.
4. Are you sure everything is right? Upload and replace the current file.
5. Try your website to see if everything works.

Are there any unexpected errors or behaviors after your update? Then it may be better to ask a web developer. Do you want to make important changes? Then try your new code first using a staging or testing location.

A WordPress children’s topic consists of at least the files “functions.php” and “style.cs”. In principle, you can also copy the other files on topics and modify them.

Your topics developer may also modify these files in future versions and you may lose significant improvements (or your website may not work properly after an update of topics).
