How to navigate to “next post/previous post”

>>Would some WP PHP expert please explain how to use these navigation tags? – That disqualifies a lot of people, including me, who are no php experts. I will hazard an answer, though 🙂
The following, from “START” to “END”, in index.php is what is fondly called “the loop”:
<?php if ($posts) { foreach ($posts as $post)"START" { start_wp(); ?>
<?php the_date('','<h2>','</h2>'); ?>
<div class="post">
<h3 class="storytitle" id="post-<?php the_ID(); ?>">" rel="bookmark" title="Permanent Link: <?php the_title(); ?>"><?php the_title(); ?></h3>
<div class="meta">Filed under: <?php the_category() ?> — <?php the_author() ?> @ <?php the_time() ?> <?php edit_post_link(); ?></div>
<div class="storycontent">
<?php the_content(); ?>
</div>
<div class="feedback">
<?php link_pages('
Pages: ', '
', 'number'); ?>
<?php comments_popup_link('Comments (0)', 'Comments (1)', 'Comments (%)'); ?>
</div>
<!--
<?php trackback_rdf(); ?>
-->
<?php include(ABSPATH . 'wp-comments.php'); ?>
</div>
<?php } }"END" else { // end foreach, end if any posts ?>
If wanted to display reverse $#$ forward on the index page, I would use
<?php posts_nav_link('$#$', 'reverse', 'forward'); ?>
just before the </div> on the second last line of the code I have posted above(which is taken from the index.php file).

put this:
<?php posts_nav_link() ?>
below this:
‘<?php } } else { // end foreach, end if any posts ?>
Sorry, no posts matched your criteria.
<?php } ?>’

I agree with Alan
Once again… state. I’m using the apr 19th nightly.
I plastered the code all over the php file. Nothing gets echoed out. In or out of the loop. (other support threads says to put it outside, wiki says to put it inside, so i just put it everywhere)
So I proceed to change the code abit…. maybe i’m just calling it wrongly. but hey!! errors abound.
So basically the function SHOULD be calling correctly… but nothing is being echoed out. boohoo… :(:(
*btw… thanks to Sushubh for replying to all my problemetic posts all over the forums*

Ok. this is going to make me sound real stupid. But I can’t find any post paged options in the options for the lastest build.
But hey!! Mr X’s code works…. but <?php posts_nav_link() ?> returns blank. Ah wellz. as long as something works!
Thanks to alan and sushubh and mr X. woot

@tedfox, depending on what version you are running, the posts pages option is at different locations…
in 1.0.2 it’s under options->other options-> what to show
in 1.2 latest cvs/nightly it is under options->reading->show the most recent -> drop down menu.
Take it easy…:)

I’ve added:
<?php posts_nav_link(' :: ', 'previous', 'next'); ?>
… inside “the loop” at the bottom. The previous/next links are appearing at the end of each post. I want it to appear only at the bottom of the page.
Any ideas? Thanks.

Thanks, rboren. That worked. I’ll see if I can make this change to the wiki docs.
