box. Like this:
<select name="modelname">
<option id="23" value="P123|23">P123</option>
</select>
Then on the action page, if you were allowing multiple selections you would
end up with a list like this:
P123|23,P124|24
Which you can loop over using the comma as the record delimiter and then
inside the loop break out the first and last value using the pipe char (|)
as the delimiter. All CFML list functions accept a delimiter.
Here is a working example:
<!--- this is the value passed from the form --->
<cfset form.modelname="P123|23,P124|24">
<cfoutput>
You selected #listlen(form.modelname)# items.
<BR><BR>
</cfoutput>
<cfset count=0>
<cfloop list="#form.modelname#" index="item">
<cfset count=count+1>
<!--- get the ID and name for each item using the pipe char
delimiter--->
<cfset itemID=listLast(item,'|')>
<cfset itemName=listFirst(item,'|')>
<cfoutput>
Item #count# ID:#itemID#<BR>
Item #count# Name:#itemName#<BR>
<BR><BR>
</cfoutput>
</cfloop>
