Throughout our Knowledge Base, you'll find pieces of code which add or modify functionality in the Mailchimp for WordPress plugin. To use these code snippets you will need to add them to your site in designated places, like the functions.php file of your active theme.
Use a plugin
The My Custom Functions plugin allows you to add custom code snippets to your site and comes with a few nifty features over the default WordPress theme editor.
Use a child theme
If you're using a theme that is built and supported by a third-party, it's a good idea to use a child theme. This will make sure that your changes will not be overwritten once your theme is updated. You can read all about how to do this in the WordPress.org Codex.
When you have a child theme in place, create a file called
functions.php within the child theme directory.
The code that you'll find throughout our knowledge base can be copy-pasted directly into your theme its
If there are any details that need to be changed before they work, we usually state this in the code snippet itself or in the article accompanying the snippet.
Make sure you copy the entire snippet of code to your file, as a missing character can lead to unexpected results.
