OK below is the HTML from my church's front page with everything except the menu part cut out. How would you change at least the "TreeMenuNav" part to PHP so I don't have to update it the way it is now on 30+ pages? Thanks in advance.
whatever file you put the code into needs to be a .php file as well. Otherwise, the server won't process any php functions in the file. So if the homepage was originally index.html before you added that code, you'll want it to be index.php with that code in it so the server then processes the statement and includes the menu.php file.
