Rock WPHow toHow To Override Plugin Function In WordPress

WordPress is a popular content management system (CMS) that powers millions of websites across the internet. One of the reasons for its popularity is the vast number of plugins available that enhance the functionality of WordPress. However, sometimes it’s necessary to override a plugin’s function to achieve a specific task or solve a problem. In this article, we will discuss how to override a plugin function in WordPress.

Here are the methods on how to override plugin function in WordPress:

Create a child theme

The first step in overriding a plugin function is to create a child theme. A child theme is a separate theme that inherits all the functionality of the parent theme. It allows you to make changes to the theme without affecting the original code. To create a child theme, you need to create a new folder in the /wp-content/themes/ directory and create two files: style.css and functions.php.

Copy the plugin function to the child theme

The next step is to copy the plugin function to the child theme. To do this, you need to locate the plugin function in the plugin’s code. Once you find it, copy the entire function and paste it into the functions.php file of the child theme.

Modify the function in the child theme

After copying the plugin function to the child theme, you can modify it to suit your needs. For example, you can change the function name or add new functionality to it. This step requires some knowledge of PHP programming, so if you’re not comfortable with it, you may need to seek help from a developer.

Add the modified function to the child theme

Once you have modified the function, you need to add it to the child theme’s functions.php file. You can do this by simply copying and pasting the modified function below the original function in the file.

Activate the child theme

The final step is to activate the child theme. To do this, go to Appearance > Themes in the WordPress dashboard and click on the child theme’s thumbnail. Once activated, the modified function will override the plugin function.


Overriding a plugin function in WordPress may seem daunting at first, but with a little bit of knowledge of PHP programming and following the above steps, it’s relatively straightforward. Creating a child theme is a critical first step in ensuring that your modifications don’t get lost when you update the original theme or plugin. Overriding plugin functions can be useful when you need to add specific functionality to your website that the plugin does not provide or when you need to fix a bug in the plugin’s code. However, it’s essential to exercise caution when making changes to a plugin’s code to avoid breaking the functionality of the website.

Things To Consider When Overriding Plugin Function

Here are some additional things to consider when overriding a plugin function in WordPress:

Check for updates: It’s important to keep track of any updates to the plugin you are overriding. When the plugin updates, it may change the function you’ve overridden, causing your website to break. Therefore, it’s essential to check for updates regularly and modify your code accordingly.

Test thoroughly: Before deploying your website with the modified plugin function, it’s crucial to test it thoroughly to ensure that it doesn’t break any functionality. Make sure to test it on different browsers, devices, and platforms to ensure that it works correctly.

Use child themes: As mentioned earlier, using a child theme is crucial when overriding plugin functions. Using a child theme ensures that your modifications don’t get lost when the original theme or plugin updates.

Consider alternative methods: Sometimes overriding a plugin function is not the best solution to a problem. It’s worth considering alternative methods, such as using a different plugin or writing your own custom function.

Backup your website: It’s always a good idea to backup your website before making any changes to the code. This way, if something goes wrong, you can restore your website to its previous state.

By considering these points, you can ensure that you override a plugin function in WordPress safely and effectively.
