Loop over form values & insert into db

Question

Form
prod_id     prod_name       prod_price    prod_status
001         product 001     1.00          1            
002         product 002     2.00          1      
003         product 003     3.00          0      
004         product 004     4.00          0      
Form Dump
prod_name      product 001,product 002,product 003,product 004
FIELDNAMES     prod_id, prod_name, prod_price, prod_status
prod_price     1.00,2.00,3.00,4.00
prod_status    1,1,0,0
prod_id        001,002,003
I want to update a few fields, prod_price and prod_status. I submit these values to my update page but I'm not sure how to loop over these values and update by the prod_id. In my update page I'm using cfdump and I see the structure of the form, the fieldnames as well as the prod_id, prod_name, etc and their values.
My question is how do I loop over these form values so I'll be able to update by each prod_id? I've played around with looping over the form collection values but no luck.

Answer 1

When I do stuff like this, I append the "id" value to the end of each form field.  That enables me to ensure the other fields match up.
When processing the form, I generally do something like this:
<cfloop list="#form.fieldnames# index="ThisField">
<cfif left(ThisField, 9) is "prod_name">
<cfscript>
ThisID = removechars(thisfield, 9);
ThisName = form["prod_name" & ThisID];
same for other fields
Then do something with those variables.
