Question

How to pass a form field to a cfc on submission

Asked by: jtheriau

I have a form that gets submitted to itself and then calls a cfc in order to do the needed db work.  This cfc then calls another cfc to upload an image file onto the server.   However I am continually getting a fun message from CF saying that "The form field fileLoc did not contain a file. "

I am trying to figure out why the field which does contain a .tmp file fro mupload - does not pass through to the image upload script properly.

The form submits and then the code goes like this....

thanks all

Is form updating ...
<cfif request.BusinessError EQ "" AND isDefined("form.updatebusiness")>
<cfset bus.bus_ID = business.SetBusiness(argumentcollection=form)>
<cfset msg = form.bus_Name & " Updated Successfully.">
</cfif>
This returns the id of the business
SetBusiness cfc looks like this...
<cfquery name="rsInsert" > Do the form field data entry</cfquery>
<!--- upload image here --->
<cfif form.bus_Logo NEQ "">
<cfset img = uploadImage(#bus_ID#,#form.bus_Logo#)></cfif>
You can see here that the file field is getting passed to yet ANOTHER CFC and uploadImage looks like this...
 
<cffunction name="uploadImage" hint="send me the upload file and bus ID and I will insert it.">
		<cfargument name="bus_ID" required="yes" hint="business ID you goof! numeric of course :)">
		<cfargument name="fileLoc" required="yes" hint="send me the file field.">
			
			<!--- Search for existing business folder --->
			<cfdirectory action="list" directory="#request.folderStruct#memberLogos" name="findFolder" filter="#bus_ID#">
				<!-- If no folder exists, create one --->
			<cfif findFolder.recordcount IS 0>
				<cflock name="crDir" timeout="30" type="exclusive">
					<cfdirectory action="create" directory="#request.folderStruct#memberLogos/#bus_ID#">
				</cflock>
			</cfif>
			<!--- Insert uploaded file--->
			<cflock name="crDir" timeout="30" type="exclusive">
				<cffile action="upload" filefield="fileLoc" destination="#request.folderStruct#memberLogos/#bus_ID#/" nameconflict="overwrite" accept="image/*">
</cflock>
<cfset fileName = cffile.clientFile>
<cfquery name="update_image">Update the business record with the 'filename'
</cfquery>		
</cffunction>

It looks like you have an argument to your method for the form field and unless you are doing any manipulation with the neo-temp temporary file, this really isn't needed unless you want to check for length to see if an image was infact being submitted. However I wouldn't name it the same as your form field to avoid conflicts.

it really doesn't matter how many levels deep your file upload is, the form scope persists for the request and is available throughout your application code, therefore simply specifying the form field name in the cffile "fileField" attribute should suffice. I would check for naming conflicts and that your method is being called after the form is submitted.

Also since you are specifying all images in your cffile "accept" attribute I would wrap the cffile call with a try/catch, since cffile will always throw a hard error when a non-image type is attempting to upload.

So I would remove:
<cfargument name="fileLoc" required="yes" hint="send me the file field.">

And wrap your file upload in a try/catch to handle non-image types gracefully

That was GREAT !  It is amazing how simple that was - thank you so so much!!!  I simply removed the cfargument line and used bus_Logo as the filefield and all was well.

I will wrap the upload in the try/catch - for now I was jut trying to get it to work.

thanks again!!!!
