header('Locatio n: ...') is not giving immediate redirect

[henryrhenryr]

I'm using Win2k with Apache 2, PHP 5.2 for my local test server.

My problem is that I think the header('Locatio n ...') function isn't sending the header immediately and the rest of my script is running before the page redirects.

I am using a $_SESSION array to transfer messages from one page to the next. I want the message available only once, then it should be deleted. I had been using the technique something like this:

if (isset($_POST['form_submitted'])) {
  //handle_form
  $_SESSION['message']=$errorMessages;
  header('Location: http://www.thissite.com/new_page.php');
}
if (isset($_SESSION['message'])) {
  $showMessage = $_SESSION['message'];
  unset($_SESSION['message']);
}
echo $showMessage;
echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post"><input type="hidden" name="form_submitted" value="v" /></form>
 

//What I want:
The form is submitted, the page reloads to itself. The form checks everything and records any errors to $errorMessages. It transfers these to the $_SESSION array and it reloads to a new page.

//What seems to happen:
As before... but after the form check, it seems to run the rest of the script, and as the $_SESSION['message'] variable is now set, it goes into the part which unset()s that variable. THEN after this it redirects. Now of course the $_SESSION['message'] is unset and I get no message!

Does this make any sense? It's a bit convoluted. This is a highly simplified version of my page just to illustrate the process. Any help is very much appreciated!

Thanks in advance!!

Heya, henryrhenryr.

Thanks for using CODE tags! Did you know that you can specify a language for your CODE tags to make your source code easier to read?

You will still need to use [/code] to close your code blocks, regardless of the language, but you can the use one of these tags to open your code block:

[code=html]
[code=javascript]
[code=php]

and so on.

Thanks!

Heya, henryrhenryr.

Call exit() after you set the redirect header:

header( ... );
exit();
