[RESOLVED] CSS Theme Switcher

Jareh

So I'm making this theme switcher for a website - and everything works just fine on IE7 - now, I'm using a php script to manage the cookies:

<?php
$theStyle    = $HTTP_GET_VARS["style"]; /* querystring */
setcookie("style", $theStyle, time()+36000, "/", "");
header("Location: $HTTP_REFERER");
exit;
?>

Now, as I said - it works just fine on IE7, but it does not work for me nor any of my friends on Firefox 3.0 (I have not tried other versions).

It saves the cookies, but it does not take me back to the site I was on before I got to the script.

It works like this:

User presses a button, user gets redirected to a site with the above script
IE7 user gets redirected back to the site with the button; theme changed.
Firefox user is stuck on the php page, stuck.

Any help would be greatly appreciated.

referer is populated by the browser. print $HTTP_REFERER to the screen to make sure it holds a value in FF3.

if not, find another way to set your new style. i.e. send a referer value in the url instead of relying on http_referer.

You could always use a line simular to this at the very top of the page that is used prior to going to the page with the script...

session_start();
$_SESSION['URL'] = $_SERVER['PHP_SELF'];

This would store the current url into a superglobal session variable.. then inside the page with the script, you can go back to your previous page like so:

header("location:".$_SESSION['URL']);
exit;

Hope that helps out..

Cheers,

mmilano, I'm not really sure what you mean by that, could you please explain?

nrg_alpha, thank you very much for your helpful reply, however it still doesn't work as it should. The new scripts works just wonderful on IE7 still, but it's still getting stuck at the firefox page. It does save the cookie, but it doesnt that you back to the page you were coming from.

Another problem is that, I cannot use any other scripts at the top of the page, since I'm already using a SSI include script for my forum - is there a way around this?

I tried to put your script at the top of the page, and do exactly as you explained; it did not work.

Also: I just got Firefox 3 so that I could test it myself - and it's with default settings, so it can't be that something is disabled - and if it were to be, I would have to tell all users to enable the setting.

I've been trying to fix this for hours now. Can anyone help, please?

I am not familiar with SSI scripts.. do they absolutely have to occupy the very first lines in your xhtml document? If not, then have my first snippet at the very top (and I do mean this literally.. as in when you open the xhtml document, the very first thing you see is the first snippet I offered). If however this SSI thing needs to occupy the very top, then I'm not sure what the solution would be.

What does your SSI script do? Perhaps there is another solution that doesn't require it? Also, just out of curiosity..if you removed the SSI script, but implemented my snippets, does it work? I have used my snippet on a site before and it worked perfectly. so I'm just curious as to how things work without the SSI script.

You should not require any special settings in a browser to accomplish what you are trying to do. Browsers like Firefox is superior to I.E (which in my opinion is complete trash). So you shouldn't need to rely on users having their browerser set up a certain way.

Yeah, it does. I have tried to do as you suggested. But, reading what you said, would the problem be that the files I'm working with are .php, and not .xhtml? Is there a difference? The SSI needs to be on the first line, but maybe there is a way around that, if we could code the two into one, maybe?

First line of index.php:

<?php require("forums/SSI.php"); ?>

stylechanger.php:

<?php
$theStyle    = $HTTP_GET_VARS["style"]; /* querystring */
setcookie("style", $theStyle, time()+36000, "/", "");
header("Location: $HTTP_REFERER");
exit; ?>

My SSI scripts manages the information from the MySQL database, from my forum so that the following scripts will work:

<?php ssi_boardStats(); ?>

and

<?php ssi_recentPosts(); ?>

Without the SSI include, the SSI scripts (the ones just above) wouldn't work.

Would it be possible to combine the SSI include script, and your script into one, so both are on line 1?

Do you have any instant messengers? Maybe we could look into the problem that way. Would make things a bit easier.

$HTTP_* are all deprecated.

Use:

<?php
  $theStyle = $_GET['style']; /* querystring */
  setcookie("style", $theStyle, time()+36000, "/", "");
  header('Location: '.$_SERVER['HTTP_REFERER']);
  exit; 
?>

Also, using $HTTP_REFERER without declaring it assumes register_globals is On, which is usually not the case (and is BAD anyways) and will not be an option in PHP6
