            I remember reading that it is a good idea to achieve this by taking a whitelist approach in the handler function. So, don't just incorporate all the posted variables. Specifically create a variable for each posted value you are expecting. Then If data is posted which you are not expecting it will not be incorporated into your program. Now I have written this I can see it is pretty much the same as the first answer.
