This is my first PHP script, so please bear with me! :)

I have a table, with each row representing a row from a database table. Each of the fields in the table are editable, so when the user edits a couple of them and hits 'Save', the appropriate ones need to be saved.

As you can see from this pastebin snippet, users can create new rows and save them.

I need to be able to save the appropriate items into the database; I have commented in where the problem lies!

At the moment, it's just saving the last outputted row.
