Old answer about the question
So, I think (hope) that will do!
In the end I did it this way.
Looks not very genius, but works.
<ul id="navigation">
<li<?php if (uri_string()==FALSE) echo ' class="selected"'; ?>><a
href="http://localhost/codeigniter/index.php">Home</a></li>
<li<?php if (uri_string()==='about') echo ' class="selected"'; ?>><a
href="http://localhost/codeigniter/index.php/about/">About</a></li>
<li<?php if (uri_string()==='impressum') echo ' class="selected"'; ?>><a
href="http://localhost/codeigniter/index.php/impressum/">Impressum</a></li>
<li<?php if (uri_string()==='news') echo ' class="selected"'; ?>><a
href="http://localhost/codeigniter/index.php/news/">News</a></li>
<li<?php if (uri_string()==='news/create') echo ' class="selected"';
?>><a href="http://localhost/codeigniter/index.php/news/create/">Create
News</a></li>
</ul>
If u know easier and better ways please write it down.
Kind regards,
Jens
