What is wrong with this conditional statement?

Question

Hi I am trying to have the navigation highlights determined by what category or page you are looking at using wordpress. Can someone tell me what is wrong with a statement like this:

<?php if (in_category('b')){ ?>
<ul>
<li><a href="#">A</a></li>
<li><a class="current" href="#">B</li>
</ul>
<?php } else { ?>
<ul>
<li><a class="current" href="#">A</a></li>
<li><a href="#">B</li>
</ul>
<?php } ?>

I am trying to use something like this but my else statement is ignored and the 'b' is always current regardless of category.

read here.

You've got to write something like:

<?php if (in_category('b')): ?>
  <ul>
  <li><a href="#">A</a></li>
  <li><a class="current" href="#">B</li>
  </ul>

Answer 2

You are either not inside a post or everything is in category 'b'.

See http://codex.wordpress.org/Function_Reference/in_category for in_category() information.
