Modifying perl upload script to handle 10 files instead of 1?
Hey there.
I've been trying to modify my file upload script so that it handles 10 files
instead of one.
i was thinking the most straightforward way would be to add a FOR LOOP?
placed strategically somewhere like just before the my variables get
declared???
the POST input name is "fileup" so maybe i could call them fileup1, fileup2
etc.
This is the upld.pl script itself.

Anyone know if i can simply wrap it in a for loop? and if so where & would
references would i need to change? I assume only the "fileup" texts?
