Form field with comma delimited value list to cfc

Question

I have a form that passes a field to an action page with a
comma delimited value.
For instance the field name is: Program_ID
value for program_ID is: 31, 32
I am able to treat this variable as a list and check its
length, and loop over the list prior to passing it to a cfc using
the attached code:
When I try and pass the variable as a string to a cfc and
invoke a query, cf no longer recognizes my var as a list.
Therefore the code attached does not function...
Is there a specific var type that will pass through as a list
and allow me to run the code block attached?
thanks
Craig

Answer 1

Ok answered my own question.. Here is the answer for those
who are interested...
initialize var for cfc in cfinvoke statement
<cfinvokeargument name="Program_ID"
value="#Form.Program_ID#">
pass argument to cfc as a string
<cfargument name="Program_ID" type="string"
required="true">
use listqualify to parse list in cfc and set new var
<cfset selectedProgramID =
ListQualify(Program_ID,"'",",","CHAR")>
use the new var in the following statement in sql code:
((Program_ID) IN (#PreserveSingleQuotes(selectedProgramID)#))
The following code handles a form field with a single value
or a comma delimited value.
