Why is this happening?

[solitario]

$err_message='#0';

header('Location: ../index.php?a=1'.$err_message.'');

Somehow, the # character and everything after it is disappearing? I tried to rawurlencode the # character, and rawurldecoded it's equivalent %23. No dice.
Anyone know what is going on here or how I could fix it?
Many thanks.

WHat do you missapearing? it can't just didsapear, something must either stop it being inserted ot has removed it.

Is that the old part of code related?

On another note the .'' at the end is nt required, this will work:

header('Location: ../index.php?a=1' . $err_message);

I know, it's very strange.
Here's the whole page.
Basically, I'm trying to put in some error handling in which if a user tries to upload an image which does not match specific dimensions, that user would then be redirected back with, e.g., "#0" in the URL. I would then use that to display an error.
Everything is working, except this $err_message variable.
Again, thanks to anyone who can figure this out.

Have you tried something like this:

<?php
  $err_message  = '#0';
  $err_string_full = 'Location: ../index.php?a=1' . $err_message;
  header($err_string_full);
?>

Also, have you debugged and made shure that $err_message is getting set?

Thanks sciguyryan.
Ok folks, the mystery deepens:
At the bottom of the processing page I wrote:

$err_message  = '#0'; 
$err_string_full = 'Location: ../index.php?a=1'.$err_message;

echo $err_string_full; die();

//The above worked just fine, producing "Location: ../index.php?a=1#0"

Now, on the index page (to which the above script redirected) I wrote:

echo $_SERVER["QUERY_STRING"]; die();

// Which produced "a=1". The anchor tag was gone.

Very strange.

[penagate]

The anchor location is not part of the query string

Does it not work at all? i.e. it does not jump to that anchor position?

The pound sign and everything after it disappears.
I've just found I'm not the only one:

#17067
Oh well, I guess I'm going to have to use javascript.
