I would have thought it would be like placing any other variable into it?
[code]$_POST[$filName];[/code]

it is

[code]
$foo['bar'] = 'test';

$a_key = 'bar';

echo $foo[$a_key];
[/code]

Rather than using the single quotes for the index/key you use double quotes, that way PHP will use the value stored in the id variable as the index/key. As currently PHP was treating your variable 'as-is' and so was tring to find a index/key called $id in the _POST array.

So eother of the following will work
[code]$_POST["$id"];
// OR
$_POST[$id];[/code]
