Chapter 6:  Using Flash Remoting with ColdFusion MX

In your ColdFusion page, you access the parameter using 

Flash.Params

, as shown in the 

following example: 

<cfquery name="flashQuery" datasource="exampleapps" >
  SELECT ItemName, ItemDescription, ItemCost
 FROM 

tblItems

WHERE ItemName='#Flash.Params[1]#' 

</cfquery>

<cfset Flash.Result=flashQuery>

Because ColdFusion converts an ActionScript data type to the corresponding ColdFusion data 
type, you can perform CFML type-specific operations on the parameter. Therefore, if a parameter 
passed from a Flash application is an ordered array, you can perform all CFML array operations 
on the parameter. 

For example, suppose you pass an array using the following ActionScript:

var array1 = new Array(); 
array1[0] = "zero"; 
array1[1] = "one"; 
myService.myMethod(array1);

You access the elements in the array in your ColdFusion page using ColdFusion array notation, 
as follows:

<cfset arrayElement1=Flash.Params[1][1]>
<cfset arrayElement2=Flash.Params[1][2]>

Note: Although ActionScript indexes start at 0, ColdFusion array indexes start at 1. 

ActionScript also supports named (associative), arrays. These arrays have the following form:

var struct1 = new Array(); 
struct1["zero"] = "banana"; 
struct1["one"] = "orange"; 
myService.myMethod(struct1);

ColdFusion converts associative arrays into ColdFusion structures. To access the associative array 
elements from 

Flash.Params

, you use structure notation, as follows:

<cfset structElement1=Flash.Params[1].zero>
<cfset structElement2=Flash.Params[1].one>

Note: You can use most of the CFML array and structure functions with ActionScript collections. 
However, one CFML function, 

StructCopy()

, does not work with ActionScript collections.
