> Hello all,
   
> I have a dynamically generated form that I need to figure out how to 
> get the data from that form in to our database. Here is the way it 
> works.  First the client types in the number of machines they have and 
> the form generates the correct number of rows so that the info about 
> each machine is located on a separate row. That all works well until 
> they hit submit (or will hit submit if I figure out the next part).  
> How do I create a cfquery that has the correct number of values so 
> that each machines data is stored correctly?
> 
> For example I will have row one with lets say three fields (Type, 
> number, issue).  Lets say a client has a problem with 10 machines.  
> The form now has 10 rows with 3 columns in each.  Each field in row 
> one is named type1, number1, issue1 and row two is type2, number2, 
> issue2, etc..  The number next to the name is placed there by putting 
> the index of the loop in the name field.  So this is where I was going 
> to use a CFLOOP inside a CFquery to create field names dynamically.  I 
> can get it to repeate the information correctly, however the problem 
> is the index of the loop does not seem to get attached to the form 
> value I am putting into the database.
> 
> I am doing something like:
> 
> <cfquery datasource="#request.datasource#">
> INSERT into tbl_ballotOrder (type, number, issue)
> Values (
> <cfloop from="1" to="#rows#" step="1" index="LoopCount">
> 
> '#FORM.type##LoopCount#', '#FORM.number##LoopCount#', '#FORM.
> issue##LoopCount#'
> 
> </cfloop>
> )
> </cfquery>
> </cfif>
