The trick is just finding the right one. :)<br /> I still think though that the reason that the previous and next post links are showing all posts instead of just one category is that you are calling thematic_previous_post_link() which by default refers to all the posts. We need to tell the previous_post_link function to only link to posts in the same category. Either filter the arguments to thematic_previous_post_link or use the wordpress functions directly in you own nav_below:</p> <pre><code>// ETC CODE function mgd_thematic_nav_below() { if (is_page_template('my-template.php')) { ?> <h3 class="additional-posts">Additional Posts</h3> <div id="nav-below" class="navigation"> <div class="nav-previous"><span class="nav-direction">Previous</span><?php previous_post_link('%link', 'Previous in category', true); ?></div> <div class="nav-next"><span class="nav-direction">Next</span><?php next_post_link('%link', 'Next post in category', true); ?></div> </div> <?php } // ETC CODE</code></pre> <p>Check out the wordpress codex at <a href="http://codex.wordpress.org/Function_Reference/previous_post_link" rel="nofollow">http://codex.wordpress.org/Function_Reference/previous_post_link</a> on how to format the link. </p> AnotherAndrew on "Conditional tag for nav_below" http://themeshaper.com/forums/topic/conditional-tag-for-nav_below#post-20242 Sun, 03 Apr 2011 01:58:14 +0000 AnotherAndrew 20242@http://themeshaper.com/forums/ <p>middlesister,</p> <p>Thanks for the suggestion but that didn't work. </p> <p>Is there not a way to use conditionals in the code I have above?</p> <p>It seems like this would work, but it doesn't:</p> <p>// ETC CODE<br /> function mgd_thematic_nav_below() {<br /> if (is_single() || is_category('10')) { ?><br /> <h3 class="additional-posts">Additional Posts</h3><br /> <div id="nav-below" class="navigation"><br /> <div class="nav-previous"><span class="nav-direction">Previous</span><?php thematic_previous_post_link() ?></div><br /> <div class="nav-next"><span class="nav-direction">Next</span><?php thematic_next_post_link() ?></div><br /> </div><br /> // ETC CODE </p> middlesister on "Conditional tag for nav_below" http://themeshaper.com/forums/topic/conditional-tag-for-nav_below#post-20235 Sat, 02 Apr 2011 08:04:26 +0000 middlesister 20235@http://themeshaper.com/forums/ <p>I don't think it is necessary to remove and replace nav_below.
