The important point is that your code should check whether the file deletion has succeeded, and that if it has failed it should print an error message. 
$thef=param('f');
$ful="../../alpha/tempf/".$thef;
unlink($ful)  or die "Couldn't unlink($ful): $!";

The error message will show up in your webserver's error log. If the filename printed is what you expect it to be, and you can't work out from the error message what the actual problem is, we can help you with that. But you will have to tell us what the error message is.
