Re: Comma separated list

$errors = "";
foreach($_POST as $key=>$val) {
	if(empty($val)) {
		$errors .= "Please enter ".$key."<br>";
	}
}
if($errors !== "") { //or check string length here
	return $errors;
} else {
...

then if they need individual checking like password or email I don't  
have to check to see if they are empty.

Best,
Karl
