Why can't I upload an empty file?

[countdrak]

Is this a cffile issue? I can't upload an empty .txt file using cffile.

This is the error I get.

No data was received in the uploaded file "log.txt".
<br>Saving empty (zero-length) files is prohibited. <br>Verify that you specified the correct file.


Whats the workd around? Is there a way to check if there is no data in the file and still be able to upload an empty file?

why upload an empty file? There isn't much sence in that.
Use cffile to create a file one instead.

<cffile action="Write"
file="fully/qualified/path/empty.txt"
output="">


If output="" doesn't work try output=" "

But why would you need an empty file on the server anyway? If it's for something you'll use in the future just do a check to see if the file exists, if not make it with the data you need to insert. if it does, read or append to it.

Thanks. I am not trying to upload an empty file, but say one of the users might try doing that and then my system breaks! Was trying to find a way where I can check-- If someone tries uploading a file to the server and the file is empty, then the code doesnt do anything or sends back a message-- "File upload failed

Cfcatch and cftry should do the trick for you.

<cftry>
<cffile action = "upload">
<cfcatch>
<cfoutput>
File Upload Failed
</cfoutput>
</cfcatch>
</cftry>
