--->
<cfcomponent hint="I handle AJAX File Uploads from Valum's AJAX file uploader library">
<cffunction name="Upload" access="remote" output="false" returntype="any" returnformat="JSON">
<cfargument name="qqfile" type="string" required="true">
<cfset var local = structNew()>
<cfset local.response = structNew()>
<cfset local.requestData = GetHttpRequestData()>
<!--- check if XHR data exists --->
<cfif len(local.requestData.content) GT 0>
<cfset local.response = UploadFileXhr(arguments.qqfile, local.requestData.content)>
<cfelse>
<!--- no XHR data process as standard form submission --->
<cffile action="upload" fileField="arguments.qqfile" destination="#ExpandPath('.')#" nameConflict="makeunique">
<cfset local.response['success'] = true>
<cfset local.response['type'] = 'form'>
</cfif>
<cfreturn local.response>
</cffunction>
<cffunction name="UploadFileXhr" access="private" output="false" returntype="struct">
<cfargument name="qqfile" type="string" required="true">
<cfargument name="content" type="any" required="true">
<cfset var local = structNew()>
<cfset local.response = structNew()>
<!--- write the contents of the http request to a file.
The filename is passed with the qqfile variable --->
<cffile action="write" file="#ExpandPath('.')#/#arguments.qqfile#" output="#arguments.content#">
<!--- if you want to return some JSON you can do it here.
I'm just passing a success message --->
<cfset local.response['success'] = true>
<cfset local.response['type'] = 'xhr'>
<cfreturn local.response>
</cffunction>
</cfcomponent>
