i am making my first PHP based template and am having trouble finding a way of adding the "active" class to a menu. It would probably have to be based on the URL as the code is saved as an extra file and then included using <?php include"menu.php";?>
Any ideas very much appreciated
thank lirpa now what would you suggest i put between the <?php if .... ?>
ok. i ended up using
<?php $page = thenameofthepage?>
on each page and
<? if ($page = index) echo 'class="acitve"?> for the home page and
<? if ($page = downloads) echo 'class=?> for the downloads, ect...
