This section deals with advanced use of The Loop. It’s a bit technical – but don’t let that scare you. We’ll start off at easy and work up from there. With a little common sense, patience, and enthusiasm, you too can do multiple loops.
First off, „why would one want to use multiple loops?“ In general, the answer is that you might want to do something with one group of posts, and do something different to another group of posts, but display both groups on the same page. Something could mean almost anything; you are only limited by your PHP skill and your imagination.
