How to Duplicate a Function in Wordpress

1. Open a Web browser on your computer and log in to your WordPress administrator console dashboard.
2. Click the 'Appearance' panel link in the left navigation bar. Click the 'Editor' link in the 'Appearance' drop-down options. The editor opens with a list of files you can edit on the right side.

3. Click the file that contains the function you want to duplicate. Highlight the function and press 'Ctrl' and 'C' to copy the function to your clipboard.
4. Click the file where you want to place the duplicated function. Click the section where you want it to execute in the PHP code and press 'Ctrl' and 'V.' This command pastes the function in the file.
5. Click 'Update File' at the bottom of the editor. The added PHP function saves to the file, and the changes take effect immediately.
