No, what I said was that you would need to create a directory ahead of time in which those files will be created. The directory needs to have proper permissions most likely 777, but if the data that they are writing is somehow sensitive, you'll need to make the nobody user the owner of the directory and give it 755 permissions. Then, instead of
open(FH, "> $myfile") ...
do
open(FH, "> somedirectorytheycanwriteto/$myfile") ...
