Archive Template in Wordpress - php

Question

I want to create an archive page template for Wordpress that will look like this:
August 2009
Post 4
Post 3
Post 2
Post 1
July 2009
Post 2
Post 1
So, basically, I want all the posts from the blog, ordered descending by date and grouped by month.
Can someone provide me the PHP code for this?
Thanks!
PS: Wordpress version is 2.8.2

Answer 1

This is a function I created a while back. It basically does what you want to do, but it's not a template. Maybe you can adapt it.
<?php
/**
* Displays a condensed list of the posts grouped by month/year.
*
* #param $order The order of the posts. Either 'DESC' or 'ASC', case sensitive.
* #param $date_prefix Whether to prefix the posts with the month/date.
* #param $display Whether to display the results or return it as a String.
*/
function condensed_post_list($order='DESC', $date_prefix=true, $display=true){
global $wpdb;
if( !in_array($order, array('DESC','ASC' ) ) ) $order = 'DESC';
$query = "SELECT ID, post_title, post_date FROM $wpdb->posts ".
"WHERE post_type='post' AND post_status = 'publish' ".
"ORDER BY post_date $order";
$results = $wpdb->get_results( $query );
ob_start();
$current_month = '';
foreach( $results as $result ) {
if( $current_month != mysql2date('F Y', $result->post_date)) {
if( $current_month ) echo '</ul>';
$current_month = mysql2date('F Y', $result->post_date );
echo '<h2>'.$current_month.'</h2>';
echo '<ul>';
}
echo '<li>';
echo ($date_prefix ? mysql2date('M j: ', $result->post_date) : '');
echo '<a href="'.get_permalink($result->ID).'">';
echo $result->post_title.'</a></li>';
}
if( $current_month ) echo '</ul>';
if( $display ) {
ob_end_flush();
} else {
return ob_get_clean();
}
}
?>

Answer 2

I used the above function, but replaced the SQL query with:
$results = query_posts('post_type=post&post_status=publish&cat=3');
This allowed me to use the excellent function #scompt.com wrote, but limit it to a single blog category.

Thanks a lot of the help. This is what I used with the code above.
function condensed_post_list($order='DESC', $date_prefix=true, $display=true)
{
if( !in_array($order, array('DESC','ASC' ) ) ) $order = 'DESC';
$args = array(
'numberposts' => -1,
'orderby' => 'post_date',
'post_type' => 'post',
'post_status' => 'publish');
$results = get_posts($args);
ob_start();
$current_month = '';
foreach( $results as $result ) {
if( $current_month != mysql2date('F Y', $result->post_date)) {
if( $current_month ) echo '</ul>';
$current_month = mysql2date('F Y', $result->post_date );
echo '<h2>'.$current_month.'</h2>';
echo '<ul>';
}
echo '<li>';
echo ($date_prefix ? mysql2date('M j: ', $result->post_date) : '');
echo '<a href="'.get_permalink($result->ID).'">';
echo $result->post_title.'</a></li>';
}
if( $current_month ) echo '</ul>';
if( $display ) {
ob_end_flush();
}
else {
return ob_get_clean();
}
}
