In my mind if you cannot avoid having those periods in the form-fields,
you have a design problem in your code. For example:

<input type="hidden" name="filename1" value="filename1.txt">
<input type="submit" name="SubmitStuff1">

<input type="hidden" name="filename2" value="filename2.txt">
<input type="submit" name="SubmitStuff2">

With this kind of stuff on the target page you get the filename by:

if( isset($_POST["SubmitStuff1"])) {
$MyFilename = $_POST["filename1"];
}

or

for($i=0;$i<100;$i++) {
if(isset($_POST["SubmitStuff".$i)) {
$MyFilename = $_POST["filename".$i];
}
}

and so forth. You never really need a period in the field name, unless
the form is produced by some other software, generator, or some
framework, but these are other issues then.
