Adding Classes to navigation

[dean5000v]

hi,

i need a way for zen cart to automatically add a class to the horizontal navigation list item depending on what page it is on. at the moment i have manually added a class to the home tab which gives it a orange background. only problem with this is when i click on other links they dont change background:

is there anyway i could grab the variable from the url and do a conditional statement.

e.g.

<li><a href="index.php?main_page=delivery_area"
<?php if ($main_page == "login") {
echo 'class="orangebackground";
}
echo '>'; ?>

i just quizkly typed something like that so u understand what i mean
