Problem with index page

I think we have a problem with index page. When index.php is loaded, it includes header.php. But there is no $section variable definition in the index page, so an error occurs.

Well, I recommended myself to add

$section = "";

in the index.php

why do you think is that necessary to create that empty $section variable? does it mean that the page is loaded before the "include" command is executed? It wouldn't make sense.

I added $section = "index"; on index.php for consistency, but you could handle it a number of different ways.

Great find, I was just sitting here trying to figure that out!

or you could add isset($section) && to the if statement this will also work. if(isset($section) && $section == "shirts"){echo " on";}

Or you could make it equal to "home" since it is the home page. But great question, I was confused myself at first.
