Email validation on submit

[criterion9]

Use SESSIONs.

$_SESSION['errMsg'][] = "Invalid Email Address"; //add array of messages to the session 

if(isset($_SESSION['errMsg']) && is_array($_SESSION['errMsg']))  {
echo "<div class=\"msg\">";
      foreach ($_SESSION['errMsg'] as $e) {
        echo "* $e <br>";
        }
      echo "</div>";    
unset($_SESSION['errMsg']); //clear the variable from session       
} 

One thing to keep in mind is that each page will need a "session_start();" at the top in order for this to work.

Like this

echo $_GET['msg']; 

Sorry for my lack of knowledge on this but where exactly do I put that? Just where I want the message to appear? And delete the rest of the code I had in there?

$err = $_GET['msg']; 

You would also need to remove foreach loop, as it can be used for an array only. And as you changed it from array $err[] to variable $err use simple echo command

if(!empty($err))  {
echo "<div class=\"msg\">";
        echo "* $err  <br>";
      echo "</div>";    
       }

OK so I have put

<?php
if(!empty($err))  {
echo "<div class=\"msg\">";
        echo "* $err  <br>";
      echo "</div>";    
       }
?>

where I want the error to appear but still unsure where your $err = $_GET['msg']; or echo $_GET['msg']; goes

[tobias.wagner]

You can place it anywhere before that piece of code, like this

$err = $_GET['msg']; 

if(!empty($err))  {
    echo "<div class=\"msg\">";
    echo "* $err  <br>";
    echo "</div>";    
} 

or do it like this

if(!empty($_GET['msg']))  {
    echo "<div class=\"msg\">";
    echo "* " . $_GET['msg'] . "  <br>";
    echo "</div>";    
}
