Question

In efforts to allow users to save their progress in my application, I’ve decided to allow them to save. In order to do this, I’d like to create an array with all the necessary information, and send that information to a coldfusion (.cfm) file and process the information from that page. Is it possible to send an array instead of a bunch of url variables? It is possible (and quite probable) that users would exceed the query string length of most browsers.

Answer 1

Yes, just use a post method instead of get. In ColdFusion this will come through the form scope instead of the url scope.

var request:URLRequest = new URLRequest(your-cf-page);
request.data = yourURLVariablesObject;
request.method = URLRequestMethod.POST  //this is the important part
urlLoader.load(request);

Put your info in the URLVariables like you usually do…

yourURLVariablesObject.whatever

will become

#form.whatever#

on CF

Just a note… if you really want to make this work well, I’d consider using AMF and an RemoteObject. ColdFusion has the advantage of being able to directly talk to Flex via AMF.

var yourService:RemoteObject = new RemoteObject("ColdFusion");
yourService.source = "yourCFFiles.yourCFC";

Now you can call any method in yourCFC
