thanks for reply. The add_query function work fine, but i need little more help. The problem I’m trying to solve is to get this modified link to main menu of the site. For example… when I create a page “test” the link for the page in main menu will be http://localhost/wordpress/page_id=1. But I need to modify that link, so when someone open “test” in main menu, the page links to http://localhost/wordpress/page_id=1?option=agument. Is there any chance to do that?
Thanks very much
