函数代码：
function recent_posts_mu($posttype = 'post',$number = 20)
{
global $wpdb;
$blogs = $wpdb->get_col("SELECT blog_id FROM $wpdb->blogs WHERE
public = '1' AND blog_id !='1' AND archived = '0' AND mature = '0' AND spam = '0' AND deleted = '0'
ORDER BY last_updated DESC");
if ($blogs) {
foreach ($blogs as $blog) {
$blogPostsTable = $wpdb->base_prefix . $blog . "_posts";
$wpdb->query("
CREATE TEMPORARY TABLE IF NOT EXISTS temp_table(
SELECT *
FROM
$blogPostsTable
WHERE
$blogPostsTable.post_status = 'publish'
AND
$blogPostsTable.ID > 1
ORDER BY id DESC
)
");
}
$thisposts = $wpdb->get_results("
SELECT *
FROM temp_table
WHERE
post_type = '" . $posttype . "'
ORDER BY post_date DESC
LIMIT 0," . $number . "
");
return $thisposts;
}
}
使用方法：
<?php
$posts = wpmu_recent_posts_mu('post',10);
foreach ($posts as $post):
$blogURL = getBaseDomain($post->guid)->domain;
$site_id = get_blog_id_from_url($blogURL);
?>
<li>
<a href="<?php echo get_blog_permalink($site_id,$post->ID) ?>" ><?php echo $post->post_title; ?></a>
<span><?php echo date("m-d",strtotime($post->post_date)); ?></span>
</li>
<?php endforeach;?>
