$errors = "";
foreach($_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.

Hi all

I've moved on to learning checking forms for valid imput and when doing thing
that are repetive, like

if ($_POST['first'] == "") {
      $errors .= 'Please enter a valid name.';
if ($_POST['second'] == "") {
      $errors .= 'Please enter a valid name.';

I can think of a slightly better way like

if($_POST['first'] || $_POST['second'] || $_POST['third'] ==){
bla bla

I think I could also use empty(), not sure though, But I belive there are much
easier ways. What would anyone here do?

If it were me, I'd use the one that uses the or operator.
