I just hacked get_all_blog_posts() a bit for a friend so she can grab the blog ID, title, and URL right from the post objects. (I'm sure you could get all that later using just the ID, but for her purposes, this was much easier.) <code> function get_all_blog_posts( $num_per_blog = 1, $orderby = 'date', $sort = 'post_date_gmt' ) { $posts = array(); $blogs = get_blog_list( 0,'all' ); foreach ( $blogs as $blog ): switch_to_blog($blog['blog_id']); $newposts = get_posts('orderby='.$orderby.'&numberposts='.$num_per_blog); foreach ($newposts as $postobj) { $postobj->blog_id = $blog['blog_id']; $postobj->blog_name = get_bloginfo('name'); $postobj->blog_url = get_bloginfo('url'); } $posts = array_merge( $posts, $newposts ); restore_current_blog(); endforeach; return _quicksort( $posts, $sort ); } </code> This is a great plugin!

function get_all_blog_posts( $num_per_blog = 1, $orderby = 'date', $sort = 'post_date_gmt' )
{
$posts = array();
$blogs = get_blog_list( 0,'all' );
foreach ( $blogs as $blog ):

$newposts = get_posts('orderby='.$orderby.'&numberposts='.$num_per_blog);

$postobj->blog_id = $blog['blog_id'];
$postobj->blog_name = get_bloginfo('name');
$postobj->blog_url = get_bloginfo('url');
}
$posts = array_merge( $posts, $newposts );
restore_current_blog();
endforeach;

return _quicksort( $posts, $sort );
}

I wrote these for a couple of widgets, so I was looping over the results directly. <code> $posts = get_all_blog_posts(); foeach ($posts as $post): echo $post->post_title; endforeach; </code> The template tags may or may not work inside the foreach loop shown here.

$posts = get_all_blog_posts();
foeach ($posts as $post):
echo $post->post_title;
endforeach;

Both MU-Helper functions loop over a list of blog IDs, and use switch_to_blog/get_posts to query for each blog's posts. I used a quicksort algorithm to mash them together in an ordered list. You can take the same approach here. Just limit your queries, and pull back only what you need to keep the process manageable. If you are caching queries (at the mysql level) and caching your results, you can optimize it even further. Depends on the loop.

The quicksort algorithm is then applied to the array so that the list of posts are sorted correctly. There is one efficient query per blog, but it only pulls in what you need (i.e. limited to just <em>N</em> posts) and shouldn't be very expensive (even for a large number of blogs). The quicksort was used to avoid complex UNIONS and other MySQL nonsense that would have made getting this data use a lot more resources than it was worth.

Everything I've read seems to imply using switch_to_blog in a loop will devour resources. I suppose I'll just use switch_to_blog if you think that'd be the best route. Thanks again Eric!
