Hi,
I'm having trouble evaluating a dynamic variable. I want to check if the
variable $_POST["resolutions$i"] is an empty string, as you'll see from the
code. However, every way I've tried to check the variable so far (including
empty() and eval()) always returns a null value, even when the variable
should contain a value. I've probably been doing something wrong in my
previous efforts. Can someone recommend a way to reliably evaluate this
variable?

for ($i=1; $i<=$entries; $i++) {
if($_POST["resolutions$i"] !== ''){
do_something();
}
}

Thanks.
