If you have gotten a number of values for a variable how can you pass them in an <input type=hidden... from a form?
I know PHP knows about arrays from forms using $whatever[] How would a hidden contain array data?
I'm answering myself because I just found an answer after posting (and yes I had searched before asking... sorry) It has to do with imploding and exploding the data and even using serialize. See http://www.faqts.com/knowledge_base/view.phtml/aid/119
