Header doesn't seem to work on web server

Question

    <?php
  session_start();
  if (empty($_SESSION['id'])) {
    $_SESSION['errMsg'] = '<div class="alert alert-danger" role="alert">
    <strong>Post:</strong> You must be logged in `enter code here`in order to post.
    </div>';
    header('Location: ../../index.php');
    exit;
  }
?>

It just doesn't redirect me to index.php, which is in the proper place, even though the session doesn't exist.

what have you tried? Did you checked your log-files? What happens, when you remove the "exit"? — Oliver, Feb 21 '17 at 07:45
Without the exit; it still doesn't seem to work. I will check if it works without GZip now, although this shouldn't be a problem. — Gouden Enderoog, Feb 21 '17 at 07:47
Yes, exit is mandatory on redirect. use a FQDN (means an absolute url like http://example.com/index.php) in your header function. — Oliver, Feb 21 '17 at 07:49
Silly question, but does `$_SESSION['id']` have a value? i.e. does your code get to the `header`? — JustBaron, Feb 21 '17 at 07:50
It has a value when you're logged in. Whenever you're not logged in it doesn't, that's why it checks if it's empty or not. If it's empty, you're not allowed to go to the page, so you'll be redirected to the index page — Gouden Enderoog, Feb 21 '17 at 07:54
So `$_SESSION['id']` IS empty? Can you echo/print something before/after the `header`? — JustBaron, Feb 21 '17 at 08:01

I understand your redirect problem

From the above code

header('Location: ../../index.php');

Your project is example.com/testfolder/view.php

Make change the Path and If your index.php is in previous folder means simply add

../index.php

Likewise monitor and set your path in the header.

It still doesn't work. On my localhost it DOES work, but it just doesn't work on Strato (Web domain host) – Gouden Enderoog Feb 21 '17 at 08:00
I think there is some problem in your code or your hosting. Ok just try it through Javascript – Sankar Smith Feb 21 '17 at 08:03

header('Location: http://myhost.com/mypage.php');

PHP header()

    <?php
  session_start();
  if (!isset($_SESSION['id'])) {
    header('Location: ../../index.php');
    exit;
  }
?>

I fixed it, I don't know how, but it works now. This is the code I use now
