trapping for null vs zero values from form input

[eleland]

Hi,

I am trying to trap for null values submitted from a web form to this script, but when the user submits the value of "0" for the $evaluatorScore, it fails the test below and sets the $error value. If I type in "00" then it works fine. I want to allow the user to submit a zero value.

if (!$evaluatorId || !$evaluatorScore || !$id || !$scored ) {

    $error = "I'm sorry. You did not fill in all of the fields.".$evaluatorScore;
if ($evaluatorScore == "0") {
	$error == "";
}
} else {

What am I missing here? I confirmed the zero value is passed correctly to the script by echoing the $evaluatorScore variable, what am I missing? Besides sleep?

Thanks,

Eric

You can use the === operator to prevent PHP from doing automatic type conversion.
