Need a PHP clue

I really need some help with this one guys. I am trying to create an edit function for my poll script. Modifying questions is not a problem, only when it comes to editing, updating, and deleting the answers possible for the poll. I'd like to do it in one step. My table is organized with a unique id for each answer to the poll, a pollid column which is uses to see which answer will be shown for what poll, and the answer it self. Each poll has a max of 5 questions, so 5 text boxes are created. In each text box, the answer is prefilled. Now here's the problem. . . I cannot figure out how to pass the info to PHP so that it knows where to find the row and do either an update, insert, or delete. I was trying to have the name tag of each text box be the unique id and the value will be an answer to the poll. Problem is that I cannot figure how with PHP to know the variable name which is passed and hence, I cannot do the tasks needed. Basically I need to pass some how, an identifier for each of the 5 answer text box so I can perform a query using WHERE. Any ideas? Thanks.
