The best way of doing this is to name the fields catid[]
The [] means that they are inserted into an array in the order they appear
on the page, so on the page with deals results you just have to cycle
through the array.
As a side point, there is no way of telling what has been modified and what
is not (well without comparing the variables to the db again).. so it is
usually quicker just to update the whole.lot.
