Safe Coding Guideline
How to safely edit your theme or plugin files
Most section of this knowledge base involve custom codes, that need to be implemented either via a code snippets plugin or placed in your theme/child theme functions.php
Before starting with any of the listed methods, make sure to have a full website back-up just in case. You never know what you may accidentally delete or change.
This method is much easier, most snippets should work all right with it.
This method is safer as you have direct access to the files and any issues can be undone quickly. However switching the theme will also turn off all custom codes, as they have to be carried over to the new theme.
- Optimally, you should use a child theme. Child theme files does not change during theme updates, leaving the changes in tact.
- Open up the functions.php file in your active theme/child theme directory via an (s)FTP file editor. Notepad++, Filezilla and WinSCP are great tools for that. We do not recommend using the theme editor that wordpress offers, for safety reasons. Tutorial here.
- The file is usually located at wp-content/themes/your-current-theme/functions.php
- Place the recommended code snippet at the bottom of that file.
- Save, and it is done
