Need a solution to display error msgs over multiple pages / requests

[jhuesser]

For example jodel.php contains the following code:

if(isset($_GET['upvotejodel'])){
//....
if(!$voted){
//....
else {
$_SESSION['errorMsg'] = "Already voted";
}
header('Location: https://jodel.domayntec.ch/jodels.php');
}

// ...
/....
f(isset($_SESSION['errorMsg'])) {
 ?>

 <div class="alert alert-danger" role="alert">
  
  <strong>Holy guacamole!</strong> <?php echo $_SESSION['errorMsg'];?>
</div>

So we need to clear the php $_SESSION['errorMsg'] after each time it's displayed, or find another soloutin....
