Question

So my issue is that I’m setting a message in a session var to carry over in a page redirect.
And then setting the var to an empty string so it doesn’t redisplay everytime.
Like so:

if ($successMsgs || !empty($_SESSION['msg_success'])) {
 $success_block[] = '<ul id="success-block">';
 foreach($successMsgs as $success) {
  $success_block[] = '<li>'.$success.'</li>';
 }
 if (!empty($_SESSION['msg_success'])) {
  $success_block[]='<li>'.$_SESSION['msg_success'].'</li>';
  $_SESSION['msg_success']='';
 }
 $success_block[] = '</ul>';
 $success_block = implode('',$success_block);
}

The problem is that the clearing of the session var seems to have a retro-active effect so the message never gets displayed. It only works if I take out the line that re-sets it to an empty string. I’m thinking there’s something about when session vars are evaluated that I don’t understand?

Answer 1

It turned out that the code beneath the redirect was getting run, before actually redirecting. The solution was simply to add an exit to the redirect function.
