I use CFCs to upload files and it works well. Just place you cffile
calls in the CFC and use the form data passed in to do the rest.
You may need the whole form structure or just part of it, it just
depends on how you structure your CFC. You can make it as generic or
specific as you like.
I would suggest a design that has a high amount of reuse (that's one of
the reasons for using a CFC!) so instead of passing in the entire form
structure and depending on the form names, you may want to consider
passing in each attribute individually and returning the cffile variable
for additional processing. Here's an example:
<cffunction name="upload" access="public" output="false"
returntype="struct" hint="returns the cffile struct">
<cfargument name="fileField" type="string"
required="true" hint="This is the name of the form field that contains
the file">
<cfargument name="acceptType" type="string"
required="false" default="" hint="Valid File Types">
<cfargument name="nameConflict" type="string"
required="false" default="MakeUnique" hint="nameConflict value for
cffile">
... MORE CODE HERE ...
<cfreturn cffile> <!--- OR Whatever you name your return variable --->
</cffunction>

Try it out! CFCs do have access to the form scope, but generally I
think people tell you to only depend on a structure, and pass in the
form scope instead. I think I have actually tried uploading a file in
one, so assuming I'm not making up past experiences (which, on occasion
I probably have done), I'm pretty sure it will work.
