How does one upload a file from flex to a cfc

HI,

I'm tryin to do this now, did you figure this out?

thanks

Johnny

Will something like this not work:

<cfcomponent>

    <cffunction name="uploadFile" access="remote" output="false" returntype="void">
        <cffile action="upload" filefield="myFile" destination="C:\temp\" nameconflict="makeunique">
    </cffunction>
   
</cfcomponent>

(where myFile is the name of the formfield containing the uploaded file's name).

This works fine from an HTML-originated POST, so I would assume it would work from a Flash-originated POST too: the CF server won't care (or even know).

Also, I'm intrigued by what you mean by the "asnc capabilities of remote object calls" comment.  Just that I don't understand what you mean, I mean.  I'm not questioning it.

Hi,

The issue here is myFile. For flex we need to pass this name as paramenter becuase it's not html form item like:

<cfcomponent>

    <cffunction name="uploadFile" access="remote" output="false" returntype="void">

    <cfargument name="file" required="Yes" type="any">
        <cffile action="upload" filefield="#arguments.file#" destination="C:\temp\" nameconflict="makeunique">
    </cffunction>
</cfcomponent>

From flex I'm getting the file using fileReference like:

private function browseAndUpload():void
            {
                fileReference = new FileReference();
                fileReference.addEventListener(Event.SELECT,fileReference_Select);
                fileReference.addEventListener(Event.CANCEL,fileReference_Cancel);
                fileReference.browse();
            }
           
            private function fileReference_Select(event:Event):void
            {
                fileReference.addEventListener(ProgressEvent.PROGRESS,fileReference_Progress);
                fileReference.addEventListener(Event.COMPLETE,fileReference_Complete);
                fileReference.addEventListener(IOErrorEvent.IO_ERROR,onLoadError);
               
                //fileReference.upload(request);
                fileName = fileReference.name;
                myFile.htmlText = fileReference.name;
                SM_RO.importNSA();
            }

filerReference have an upload method to upload the file but I can't use that becuase I need to process my upload with my cfc.

I'm getting an error:

Failed to import the file. The cffile action="upload" requires forms to use enctype="multipart/form-data". Please also make sure the file is not open.

I can't find the way to setup the enctype becuase again i can have html form items in flex, or I can?

Thanks

Johnny

I'm making this up as I go along a bit, but I would not worry so much about the CF error message saying the form needs to have that enctype.  What it means is the HTTP request needs to have a content-type of multipart/form-data.  It doesn't matter how it gets to be sent like that... a form-tag attribute, or just setting the header via some other mechanism: neither the web server nor CF will know/care how it goes done.

A case in point is that one doesn't need to post to that CFC method via a form... one could just as much post if via <cfhttp>.  There's no forms involved in doing it that way; just CF creating an HTTP request.

Now... I don't know Flash from... err... Adam, but I'm "certain" that if CF received the request in the correct format (so the corrent content-type, and a field with a file in it), the CF side of things would work fine.

It's just a matter of coercing Flex to do that for you with Flash.  Which might be a question for a Flex forum, not a CF one..?  The question, I think, is more "how do I upload a file using Flex" rather than "... to a CF server".

Got it, I try flex forum but no help.

It works fine if I use a cfm file like this example:

But like I said before, i want to use the cfc.

Thanks
