I need to append each Post URL in my RSS feeds with the following:
?some-text-here
Therefore, a link back to a post in my blog in the RSS would look like:
http://www.mydomain.com/blog/post/?some-text-here
Is there a way to use the functions.php to add some code to automatically add that text to the end of all URLs? I know I can edit the code WordPress files, but that is not smart if I then need to change it each time I upgrade. It is best I think to make the change to functions.php
