Form field value?

[alanzhao]

Hi, are fields of a form always set even if nothing is entered?

for example:

<form>
<input type="text" name="user">
</form>

is $_POST['user'] always set by isset() even if nothing is entered?

Thanks!

:rolleyes:

try it:

<?

   if(isset($_POST['submit'])) {

  if(isset($_POST['name'])) {
     echo "Name is set";
  } else {
     echo "Name is not set";
  }

   } else {

?>

  <form method="post" action="<?= $PHP_SELF ?>">

  Name: <input type="text" name="name"><br><br>

  <input type="submit" name="submit" value="submit">

  </form>

<?

   }

?>
