Coldfusion enctype multipart/form-data cannot access other form data

Hi,

I have created a form using the <cfform> tag and because part of my form requires a file upload I have set the enctype to multipart/form-data however when doing this the file is uploaded but I cannot access any of the other form fields data. If I remove the enctype I cannot upload the file but I can access the other form field data.

Any ideas ?

Thanks

Martyn

Is there a URL where we can look at the form?

Sadly no, it's an internal admin portal i'm creating. The company would not allow me to show / post etc. I think this maybe my downfall.

Just ran that scenario on my server and it's working as intended. Without being able to see your code, I can't really help diagnose your issue. :/

BTW, this is the code I ran:

		<cfif isDefined("form")>
			<cfdump var="#form#">
			<cfif isdefined("form.filefield")>
				<cffile action="upload" destination="test" filefield="FORM.fileField" nameconflict="makeunique">
					<cfdump var="#file#">
			</cfif>
		</cfif>
		<cfform method="post" enctype="multipart/form-data" format="">
			<cfinput name="textField" type="text" value="Test Text">
			<cfinput type="file" name="fileField" >
			<cfinput type="submit" name="submit" value="Submit"> 
			
		</cfform>

If it helps, I get a

struct: [empty]

on the result of a cfdump var = form.

Thanks

The cfdump routine allowed me to investigate more to find the cflocation tag I left in there causing the form data to be lost.

Many thanks
