Get Permalink of Network Blog Post

1. That sounds pretty simple.

   Use: http://codex.wordpress.org/Function_Reference/switch_to_blog

   To go back use:

   restore_current_blog();
   

   This allows you to switch from site to site.

   Then: http://codex.wordpress.org/Function_Reference/get_permalink

   My assumptions are that you have both the Blog ID and the Post ID.

   If that’s the case – using those two functions should solve your problem.

2. As per the suggestion above, I’ve gone for this:

   $html = '<ul>';
   foreach ( $recent_across_network as $post ) {
   
       switch_to_blog( $post->blog_id );
   
       $postURI = get_permalink( $post->ID );          
       $html .= '<li><a href="' . $postURI . '">' . $post->post_title . '</a></li>';
   
       restore_current_blog();
   }
   $html .= '</ul>';
   

   where $recent_across_network is a list of recent posts from across a multisite network, cached using the Transients API. There’s a related tutorial here.

   You could equally do:

   $postURI = get_blog_permalink( $post->blog_id, $post->ID );
   

   instead of switch_to_blog() / restore_current_blog() – not sure which is more efficient?
