CFFILE Upload in a CFC
I keep seeing people get tripped up over this, so here's what the deal
is. The biggest thing you have to remember about cffile's upload is that
no matter what, the filefield <b>has</b> to be the name of the form
field
that you're trying to upload.
Example:
<cffile action="upload" filefield="form.something" destination="c:\">
Note the lack of pound signs. That means that you're forcing cffile to go
look for form.something and grab the data stream out of it. So, what do you
have to do if you put it in a CFC? You can't pass the datastream into a
CFC (you can, but that's not the correct way to do it). You have to pass
the name of the file field into the cfc instead.
Example CFC:
<cfcomponent name="fileio">
<cffunction name="fileUpload" access="public" returntype="struct">
<cfargument name="fileField" required="true" type="string">
<cfargument name="destination" required="true" type="string">
<cffile action="upload" filefield="#arguments.fileField#"
destination="#arguments.destination#">
</cffunction>
</cfcomponent>
Not the pound signs around arguments.fileField. Why? Because you're
evaluating the value of arguments.fileField which is actually a string:
'form.something'. Example usage would be:
<cfscript>
fileObj = createObject('component','fileio');
fileObj.fileUpload('form.something','c:\');
</cfscript>

I had the same exact problem a while ago!
Didn't get a fix for it from the list either actually.
It would seem to be a bug.

You can only specify a form scope variable in cffile - however - you can
pass the 'name' of that form via argument.
Example!
ohfile('c:\','form.whatever');
<cffunction name="ohfile" access="public" returntype="any">
<cfargument name="thepath" type="any" required="true" />
<cfargument name="thefield" type="any" required="true" />
<cffile action="upload" filefield="#rguments.thefield#
destination="#ExpandPath('arguments.thepath')#">
<cfreturn cffile>
</cffunction>

I'm not sure exactly what you're trying to do, but I can upload via a cfc
with the following:
the form file:
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<form action="my_action_page.cfm" method="post"
enctype="multipart/form-data">
File: <input type="file" name="aFile"><br>
<input type="submit" value="Upload a File">
</form>
</body>
</html>
the component:
<cfcomponent displayName="Upload Foo">
<cffunction name="uploadFoo" access="public" returnType="boolean"
output="false">
<cfargument name="theFile" type="any">
<!--- uploadFoo body --->
<cfset var retVal = true>
<cftry>
<cffile action="upload" filefield="aFile"
destination="C:\mypath\uploadTest\">
<cfcatch>
<cfset retVal = false>
<cfrethrow>
</cfcatch>
</cftry>
<cfreturn retVal>
</cffunction>
</cfcomponent>
the action page:
<cfinvoke
component="dot_path_to_my_cfc_file"
method="uploadFoo"
returnvariable="uploadFooRet">
<cfinvokeargument name="theFile" value="#form.aFile#">
</cfinvoke>

I believe you are right. This is to prevent malicious access to the client
machine. Instead they must manually specify a file to be uploaded to the CF
server.

Ok, curious if anyone has some insight. I'm having delimmas with cffile and
a cfc. Basically I am using cffile in my base cfc so I can call on demand
for a project I'm working with. But everything I seem to do causes cf to
bail.
I've Simplified the function down to the nth degree hoping to get it to
work, but it for some reason still kicks out on me.
<cffunction name="ohfile" access="public" returntype="any">
<cfargument name="thepath" type="any" required="true" />
<cfargument name="thefield" type="any" required="true" />
<cffile action="upload" filefield="arguments.thefield"
destination="#ExpandPath('arguments.thepath')#">
<cfreturn cffile>
</cffunction>
The form field "FILE" did not contain a file. Is the lovely error I get.(
Its the same error I would get if I had #'s in the filefield on just a basic
action page.) If I do a cfdump on the variables I get
C:\CFusionMX\runtime\servers\default\SERVER-INF\temp\wwwroot-tmp\neotmp4204.tmp
or a variant on it (#'s of neotmp could be different).
Stan Winchester had a similar post that I found in the archives, though I
couldn't see a fix or a reasoning. Angel Stewart
Subject: CFFILE uploading within a CFC, with formfield as a CFC Argument.
Did as well, . though again no fix or reasoning.
I do, to a point understand what the whole "tmp" thing is, . but when I'm
passing to the cfc as an argument it just hasnt worked. my entype is
correct, (though obviously if it's set to text/ or /application it's dumping
correctly - but can't be used in cffile) The behaviour is sporatic, .
happens here and there, but not everywhere type of thing. More often does
than doesnt.
Anyone have a clue on why it's doing it? or what I can do to avoid it? I
don't have a problem using a cfm page just for the uploading, just blows
leaving out one bit. I've also tried uploading without the use of the
function that is calling it. But anytime it's in a function it's kicking.,
Sorry for the long post,. just wanted to give all *I* knew.
Thanks again ,
Robby
