if !isset multiple OR conditions

Question

I cannot get this to work for the life of me, it is PHP.

Answer 1

When you work with POST, use empty(). because when your form send data. It async null for empty input! best way is that:

 if ((!isset($_POST['ign']) || empty($_POST['ign'])) &&
     (!isset($_POST['email']) || empty($_POST['email'])) {

YES! It's Ugly...

So you can use:

<?php
 if ( checkInput($_POST['ign']) || checkInput($_POST['email']) ) {

  echo "Please enter all of the values!";
    }

 else {

   echo "Thanks, " . $_POST['ign'] . ", you will recieve an email when the site is         complete!";

    }

 function checkInput($input){
     return ( !isset($input) || empty($input) );
 }
?>

Answer 2

You can try this code:

<?php
    if(!isset($_POST['ign'], $_POST['email'])) {
        echo "Please enter all of the values!";
    } else {
        echo "Thanks, " . $_POST['ign'] . ", you will receive an email when the site is complete!";
    }
?>
