post_nav_link WordPress
- SOLVED
Hey,
I got a pretty simple and basic loop and I'm looking to tweak the previous/next_post_link
Here's what I have now:
<div id="postnavi">
<div class="alignleft"><?php previous_posts_link(); ?></div>
<div class="alignright"><?php next_posts_link(); ?></div>
</div>
And I would like to display a list of the previous posts, the ones that show up on page/2/ and page/3/. Basically what I'd like is to offset one list by 10 (or any other number) and the other list by 20 so I have 2 lists on each subsequent page.
A good example of what I mean would be http://www.treehugger.com/
See at the bottom where it says 'Keep Rolling. Hit the Next Page >' that whole section is what I'm looking for. I was able to get it to work on the homepage by create a WP query and offsetting the list, but then on page/2 it stops working (obviously)
Any help with this would be greatly appreciated ;)
EDIT: I think Lew's solution would work pretty well. Lemme just try it out and I'll select the winner shortly. Thanks!

Lew Ayotte answers:
At the end of your loop, you should run another query_post
something like:
query_posts('posts_per_page=10&offset=10');
and
query_posts('posts_per_page=10&offset=20');
after each query_posts you'll have:
if (have_posts()) : while (have_posts()) : the_post() :
<a href="the_permalink()">the_title()</a>
excuse the poor PHP/HTML formatting :)
You'll need a way to keep track of the actual offset too... let me think about it for a minute.

Lew Ayotte comments:
Ok, so the offset variable will need to be calculated something like:
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$offset1 = $paged * 10;
$offset2 = $offset1 + 10;
query_posts('posts_per_page=10&offset=' . $offset1 . '&paged='. $paged);
your loop...
then...
query_posts('posts_per_page=10&offset=' . $offset2 . '&paged='. $paged);
your loop...
does that make sense?

Lew Ayotte comments:
Actually, you know what...
you shouldn't need to calculate the offset if you're using paged...
so this would be it:
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts('posts_per_page=10&offset=10&paged='. $paged);
your loop...
then...
query_posts('posts_per_page=10&offset=20&paged='. $paged);
your loop...

Lew Ayotte comments:
You'll notice... to get the page/3/ link I used the get_pagenum_link function w/ the $paged var:
<div class="navigation">
<div class="alightright"><a href="<?php echo get_pagenum_link($paged + 2) ?>">Next 10 after that »</a></div>
</div>
Lew Ayotte comments:
You'll also need a way to handle the "last page"... so it doesn't try to go to a "next" page...
Tree Hugger's second to last page - http://www.treehugger.com/page11.php
Tree Hugger's last page - http://www.treehugger.com/page12.php
Something like:
global $wp_query;
if ( !$max_page ) {
$max_page = $wp_query->max_num_pages;
}
if ($paged <= $max_page) {
// do stuff
}
Erez S answers:
I don't realy understand what do you need,but in the end you said that you tried to create query but the pages don't worked,well the solution is simple:
query_posts("category_name=somecat&".((get_query_var('paged')) ? get_query_var('paged') : 1));
Enjoy

This is full code to your problem:
<?php
$pagenum = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts('posts_per_page=10&paged='. ($pagenum+1));
if(have_posts()): ?>
<div style="float:left;"><h2>The <?php next_posts_link('Next Page'); ?> Contains:</h2>
<?php while(have_posts()) : ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php
endwhile;
?></div><?php
endif;
query_posts('posts_per_page=10&paged='. ($pagenum+2));
if(have_posts()): ?>
<div style="float:right;"><h2>The Page After That Contains:</h2>
<?php while(have_posts()) : ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php
endwhile;
?></div><?php
endif;
?><br style="clear:both;" />

And here is improvment which will show random posts if it the last page or page before last:
<?php
$pagenum = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts('posts_per_page=10&paged='. ($pagenum+1));
if(have_posts()): ?>
<div style="float:left;"><h2>The <?php next_posts_link('Next Page'); ?> Contains:</h2>
<?php while(have_posts()) : ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php
endwhile;
?></div><?php
else: $nopost=true;
query_posts('posts_per_page=10&orderby=rand');
if(have_posts()): ?>
<div style="float:left;"><h2>Articles Beyond Include:</h2>
<?php while(have_posts()) : ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php
endwhile;
?></div><?php
endif;
endif;
query_posts('posts_per_page=10&paged='. ($pagenum+2));
if(have_posts()): ?>
<div style="float:right;"><h2>The Page After That Contains:</h2>
<?php while(have_posts()) : ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php
endwhile;
?></div><?php
else:
query_posts('posts_per_page=10&orderby=rand');
if(have_posts()): ?>
<div style="float:left;"><h2><?php if(isset($nopost)){ ?>And Also...<?php }else{ ?> Articles Beyond Include: <?php } ?></h2>
<?php while(have_posts()) : ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>

Are you adding this to single post, or the page that lists many posts? (index, page/2, page/3)?
Utkarsh Kukreti comments:
Try this code
<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts('posts_per_page=10&paged='. ($paged+1));
echo 'The next page contains';
if(have_posts()): while(have_posts()) : ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php
