I want to display posts links from a category group by year. Group by year becouse by default wordpress repeat the date for each post. I try use a code but I got all post in current year. How can I do it? Example I want to do:
2010
- post link 20
- post link 19
- post link 18
- ...
- post link 8
2009
- post link 7
- post link 6
- ...
The code:
<?php
query_posts(array('nopaging' => 1, /* desabilitar a paginacao pata obter todos os pots. O padrao e ordenado pela data */));
$prev_year = null;
query_posts('cat=27');
if ( have_posts() ) {
while ( have_posts() ) {
$this_year = get_the_date('Y');
if ($prev_year != $this_year) {
// Year boundary
if (!is_null($prev_year)) {
// A list is already open, close it first
echo '</ul>';
}
echo '<h2 class="titulo-conteudo">'. $this_year . '</h2>';
echo '<div class="barra-amarela-4"></div>';
echo '<ul>';
}
echo '<li>';
// Imprimi o link do post.
the_post(); ?>
<div class="entry">
<h2 id="post-<?php the_ID(); ?>">
<a href="<?php the_permalink(the_title()) ?>"><?php the_title(); ?></a></h2>
</div>
<?php
echo '</li>';
$prev_year = $this_year;
}
echo '</ul>';
}
?>

Reset to default 2I wrote that original code on Stack Overflow, but I didn't see your further replies because you posted them as answers and not as comments to my answer. I have tested the code now with a specific category and it works for me, but it needs one crucial change: the call to the_post() (which I completely forgot) must come right at the beginning of the while ( have_posts() ) loop, otherwise the year will always lag one post behind. I have corrected that in the original answer.
If you want to specify multiple criteria for your query, you must combine them in the same function call. So not query_posts('cat=27'); query_posts('nopaging=1');, but query_posts('cat=27&nopaging=1'). You can also use the array format (as in my original example), I prefer that for readability.
A last change: if this is not the main loop of your page (and I suspect this code will end up in a sidebar, so not the main loop), [it is better not to use query_posts()][2]. Instead, try get_posts() and use the result of that. I did not know this when I wrote the original answer, but hanging around on this site learns you a lot!
What you have looks to work well.. Since I was on here looking for solutions to another question I posted and came across this one, I thought I'd add how I accomplished this in one of my sites:
<?php query_posts('posts_per_page=-1&category_name=podcasts');
$dates_array = Array();
$year_array = Array();
$i = 0;
$prev_post_ts = null;
$prev_post_year = null;
$distance_multiplier = 9;
?>
<div class="post">
<!--h2 class="title">< ? php the_title(); ?></h2-->
<div id="archives" class="entry">
<?php while (have_posts()) : the_post();
$post_ts = strtotime($post->post_date);
$post_year = get_the_date('Y');
/* Handle the first year as a special case */
if ( is_null( $prev_post_year ) ) {
?>
<h3 class="archive_year"><?=$post_year?></h3>
<ul class="archives_list">
<?php
}
else if ( $prev_post_year != $post_year ) {
/* Close off the OL */
?>
</ul>
<?php
$working_year = $prev_post_year;
/* Print year headings until we reach the post year */
while ( $working_year > $post_year ) {
$working_year--;
?>
<h3 class="archive_year"><?=$working_year?></h3>
<?php
}
/* Open a new ordered list */
?>
<ul class="archives_list">
<?php
}
/* Compute difference in days */
if ( ! is_null( $prev_post_ts ) && $prev_post_year == $post_year ) {
$dates_diff = ( date( 'z', $prev_post_ts ) - date( 'z', $post_ts ) ) * $distance_multiplier;
}
else {
$dates_diff = 0;
}
?>
<li>
<span class="date"><?php the_time('F j'); ?><sup><?php the_time('S') ?></sup></span>
<span class="linked"><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></span>
<span class="comments"><?php comments_popup_link(__('0 comments', 'warp'), __('1 comment', 'warp'), __('% comments', 'warp')); ?></span>
</li>
<?php
/* For subsequent iterations */
$prev_post_ts = $post_ts;
$prev_post_year = $post_year;
endwhile;
/* If we've processed at least *one* post, close the ordered list */
if ( ! is_null( $prev_post_ts ) ) {
?>
</ul>
<?php } ?>
</div><!--entry-->
</div><!--post-->
This eliminates multiple query_posts calls and is really easy to control styling, etc.. hope this helps someone who may be wanted to see various solutions to this :)
Great work again, on your orig. solution.
You need to run a posts query that gives both the category and year values (as well as your nopaging, which is best done with posts_per_page=-1)
See the codex article for query_posts() for full details about prarameters you can pass into new WP_Query().
Here's the code for your question:
/**
* Run a query for a specific category (cat=$cat_id) and year (&y=2008)
* Also turn off the paging by setting posts_per_page to -1
*/
$year_and_category_query = new WP_Query("cat=$cat_id&year=2007&posts_per_page=-1");
/**
* Run the loop on your new query
*/
while ($year_and_category_query->have_posts()) : $year_and_category_query->the_post();
// Use the post with functions like the_title, or use the now global $post
endwhile;
Your code got very broken when posted. From what I can see multiple query_posts() are bad idea in most cases. Please correct your code if you want better assessment.
Personally I would use plugin for this, there are plenty of excellent archive plugins around. I currently play with Smart Archives Reloaded. It allows easily to get posts by month/year in specific category:
smart_archives( array(
'format' => 'list',
'include_cat' => 27
));
