Bug not mentioned in the video

After setting up $section value in shirts and contact page, it is true that these pages are working exactly as expected, but if you switch the index page, you'll see a messed up header.

I inspected the element, found the cause of the bug: $section is undefined in index page. So I give the value like 

$section = "index";

I think it's important to include this in the video

Hi Zerui,

It's not mentioned in the video because possibly it wasn't discovered until afterwards. The fix is included in the project files though. I think it should be mentioned in the Teacher's Notes.

My solution was to do this:

<li class="shirts<?php if ( isset($section) && $section == "shirts") { echo " on"; } ?>"><a href="shirts.php">Shirts</a></li>
<li class="contact<?php if ( isset($section) && $section == "contact") { echo " on"; } ?>"><a href="contact.php">Contact</a></li>
<li class="cart"><a href="#">Shopping Cart</a></li>

By checking if it's set first you don't have to worry about setting the $section variable on pages that aren't going to use it.
