The above is a good start. But you can't just start typing "<form name..."
inside a function block. You need to use

print "<form name='cooler' ....";


I always do my web app logic like this:


<?
while (1){
if ($_POST["file"]){
# Do fancy stufff
break;
}

# output form
$dir = "/inetpub/wwwroot/templogs/";
# ...

break;
}
