for now i have 2 result, but if i choose the item "diamond" ,the session passed the "iphone4 by kokfui" to new php, i think this is because the looping have cleared the "diamond" information, anyone can help me solve this??thank you very much

certainly session don’t pass wrong id (it has nothing against you and will pass what ever you give). I would recommend reading any PHP tutorial don’t try to go to a stage when you don’t know the basics of a previous one.
