pass an associative array containing data to form_upload

Was looking at the post Multiple File Upload in the forum. Apparently I'm missing a lot. Followed the code okay but don't really see how I could get there based on the info on the site. Like is the associative array supposed to be on the view page with the function call? Also not sure how to use the library properly. Where do I need to look to for that info? Are their other resources for learning code igniter?

Doing gee I don't know so let's try it 27 different ways is a non starter. For instance I already did the full application using just functions but wanted to put it in code igniter. What's the best way to attempt to master CI?
