First off, I'm not a php programer. Otherwise I know how to use some code and I do it frequently for fairly easy stuff.
But I don't understand what I have here or exactly how it's working. I'm using code that outputs posts in rows. I also have code that outputs all authors who have posts. I put them together and it works.
It appears to be using the main loop, and I've never done anything before which alters the loop without using query_posts in front of it.
It's getting authors through something called "global $wpdb"
then, it comes to what appears to be the loop. At that point it has the code which does the rows output.
A minimal expalnation of how this is working would be great. I'm trying to figure out if it can have paging. I added the code I normaly add for paging query_posts, but I have no idea how I would get the loop to accept arguments. I actually expect that if this is using "the loop" it should already have paging...?
Any help understanding how this works or how to get paging would be great. Thanks!
