ColdFusion: get the name of a file before uploading

How can I get the filename of a file before I call the 

<cffile action = "upload">

? I can get the filename of the temp file, but not of the actual filename. In PHP land I can use the $_FILES superglobal to get what I want - but as far as I can tell no such thing exists in ColdFusion.

I can get the filename client-side but would really want to do this server side.

Thanks

Yes this is possible. You can use this function to grab the client file name before using the cffile tag:

<cffunction name="getClientFileName" returntype="string" output="false" hint="">
    <cfargument name="fieldName" required="true" type="string" hint="Name of the Form field" />

    <cfset var tmpPartsArray = Form.getPartsArray() />

    <cfif IsDefined("tmpPartsArray")>
        <cfloop array="#tmpPartsArray#" index="local.tmpPart">
            <cfif local.tmpPart.isFile() AND local.tmpPart.getName() EQ arguments.fieldName> <!---   --->
                <cfreturn local.tmpPart.getFileName() />
            </cfif>
        </cfloop>
    </cfif>

    <cfreturn "" />
</cffunction>
